PIC Student Course Notes Welcome to the PIC Course This notebook has all sorts of information that can be used in conjunction with your classes. The book lists background information and further areas of research for your major areas throughout the year. It has links to other sources of information if your reading this on a computer connected to the internet. The course is broken down into four major areas of study. • Camera • Studio • Output/Darkroom • Folio Have a read if you have any suggestions for improvement let us know, [email protected] Camera The Eye and the Camera Looking at the human eye helps us understand how the camera works. The lens of the eye is like the lens of a camera. In both the eye and the camera: the lens focuses an image of the surroundings on a light sensitive surface - the retina of the eye and the film of the camera. the light sensitive material is protected within a light-tight container - the eyeball of the eye and the body of the camera. a mechanism shuts off the light passing through the lens to the interior of the container - the lid of the eye and the shutter of the camera. the size of the lens opening [aperture], is regulated by the iris diaphragm But there are important differences: The eye adjusts automatically to high and low light conditions in a dark room the iris of the eye opens wide to allow as much light as possible to enter. in bright light the iris closes down to prevent too much light from entering. The eye continually shifts it’s focus as you move your eye around Observe the pupil in your own eye in a mirror as you switch a bright light on and off. You will see the iris adjust the size of your pupil accordingly. Adjustable cameras don’t adjust for extreme light conditions automatically. You must regulate the light entering the camera. Some newer cameras have semi-automatic features to help you do this. The eye sees selectively, the camera sees indiscriminately. People observe only details relevant to them. Their minds filter out what they don’t need to see. The camera sees all details in the view and records all details on the film.e.g. when your photo has a pole or tree growing out of your subject’s head. The photographer saw only the subject but the camera saw all details in its field of view. As a photographer you must train yourself to see what the camera sees. Note : A detailed chapter on this topic is to be found in A.Feninger, ‘The Complete Colour Photographer’ ISBN 0 500 01061, Part iv, available in the PIC library Camera Care and Handling. Parts of the Analogue Camera Function of the parts of the camera How handle/shoot with a camera. Composition? Parts of the camera. A camera is a light tight box, with a lens attached. Today’s modern cameras have very sophisticated controls, that allow the operator many choices. Some of the controls are necessary others sometimes hinder creativity. The majority of modern handheld cameras have a built in light meter, a dial to control shutter speeds and a dial to control the aperture usually situated on the lens. This is all we need as creative individuals, any thing else is an add on. Handling cameras. Never, ◆ ◆ ◆ ◆ Always, ◦ ◦ ◦ ◦ Touch the lens. Touch the shutter curtains. Drop the camera. Expose the camera to sea, salt,water, extremes of heat and cold Wear the camera strap. Use a Lens hood Leave the UV filter on Keep the lens cap on when not in use Holding a camera to shoot. Assuming we want the most photographic quality of images we can possibly produce we need to follow a few basic guidelines. Pay attention to these points: • Grip Stance When holding a camera, tuck your elbows in, spread your feet squarely apart and try and make your whole posture as steady as possible. Support/s If possible use any or all extra support you can. This could be a tripod or a wall to lean on, Composition? Composition is one of the most important aesthetic considerations that is applied to all photography. It is a simple and powerful way to add all the extra emphasis you need to any image. There are only a few guidelines to making a good composition. but ultimately the guidelines are simply here to help us be better photographers. • Stance • Support/s Grip Hold the camera firmly in your hands, rest the camera in the palm of one hand and wrap the other around it, keep your fingers clear of the lens]. When pressing the shutter, gently stroke or squeeze it. Jabbing or stabbing ‘might’ produce camera shake. 5 Maintain & prepare photo equipment. Camera use - Do’s [Analogue] 1.

Once film is loaded in camera , check that rewind exposures on your film or getting all the exposures on the first frame only. Change the ISO speed and check that light metre indicates more exposure needed as ISO speed is lower and less exposure needed as ISO speed is increased. Always support camera when opening camera back so that back doesn’t swing out and flop open. This puts pressure on back’s hinges and can bend the actual back so that it does not close properly. Check inside camera for dust, particles etc. Gently blow out with blower brush. If they are visibly dirty or greasy, wipe film tracks or film pressure plate very Change speed and release shutter.

If light meter , shutter button, shutter speeds, apertures, ISO etc, are not functioning then camera must be sent for repairs Look through viewfinder to check that viewfinder is clear and that lens is not dirty. Check battery compartment is clean. Batteries should be replaced at regular intervals. If using a Flash, attach the flash and fire off a test flash. Check any other extra Camera Use Don’ts 1. Never point cameras directly at the sun. 2. Always attach the lens hood. 3. 4. 5. 6. 7. This will prevent flare and give some protection to the lens body from knocks. Wear the camera strap so that there is no danger of the camera being dropped. If moving from a cold area to warm, allow camera to warm up before shooting. You may get condensation on lens. Don’t touch lens with fingers or wipe lens with hankies, normal tissues etc. Don’t use any cleaning fluids on camera bodies. Blow off dust with blower brush or wipe gently with lint free cloth. Keep all photographic equipment away from food, smoke, gases, chemicals, heat, humidity, dust, water, especially salt water. Maintaining the Camera Lens. 1. Keep a UV filter on the lens at all times. This will protect the 2. 3. functions your particular camera may have. 4. 5. actual surface of the lens as well as filtering out the sun’s [blue] ultra-violet rays. Keep the lens cap on to protect lens when you are not shooting. Dust or small particles on lens should be gently swept off or blown off with blower brush. Greasy finger prints or other water or grease marks may be removed by special lens tissue. More stubborn marks may require the lens tissue to be moistened with lens cleaning fluid. 6 Camera Pre-Shoot Checklist Use this check sheet before you commence any planned shoot.

Pictures can be beautiful, powerful emotional and riveting. They can decorate a space like a gallery or home; be published in many formats including books magazines and now online. A well executed landscape can lift the viewer back to another time and place. A still life can evoke hunger, capture a mood of serenity, warmth. A powerful portrait of a person can look into their soul, and let you share their lives of smiles, anguish or tears. A great picture communicates. Think about it. There is a huge market out there for photographs because publishers know that the people who buy their materials will be drawn to good photographs that reach out to them. Visual communication is something that we’re all born being able to relate to. ‘Seeing comes before speaking’. Your subject matter is only limited by your imagination. But what makes a photograph successful? The answer is a fairly simple one, and you can improve your photography today by learning a few very basic rules. One disclaimer, though. As the old saying goes, rules are meant to be broken. Some of the best photographs very purposely break a lot of the basic “rules” of photography. But to break the rules in a way that enhances a photograph and effectively turns it into a great photo, you first have to know the rules and have a reason for wanting to break them. So today we’re going to talk about simple photographic rules that will make your pictures better.I call these rules guidelines and they are called the three P’s, Proximity, Position and Point of View. Proximity The first 3 rules for proximity are:Get Closer. Get Closer. Get Closer. Fill the frame with as much of the subject as you can, are able, dare or have time to. This will demonstrate what it is you are photographing, very quickly and clearly. Position Most really strong photographs position their main elements in certain specific places of the frame. When you think about where you put your subject in the photograph, you are composing your image. Think about it. When a painter starts out with a blank canvas, he or she has free reign to decide where to put that river, those mountains, the trees, clouds and anything else that needs to be included. Creating a photograph, you should go through the same process. Nine times out of ten when I see a photo of the flower with Barbie or some other object lying in the background, the flower itself has been dead centre in the frame. This is simply natural instinct for us to compose a photograph this way. When we are looking at the flower, our eyes are focused directly in front of us. We don’t put the flower on the table, bring our ear down to the flower and then try and shift our eyes to see the flower out of the corners of them. Some part of our brain knows that and wants to place the subject right there in the middle of the frame, where our eyes would normally look. The trick is to realise that when the picture is taken and all is said and done, you will have that small rectangle to hold out in front of you and look at, and then you can look at it by focusing your eyes straight forward. Until then, forget about centreing your subjects. This is a harder concept to master than you might believe at first. Once you try it a few times and see for yourself with your own images the difference that it makes, it will get much easier. There are several “classic” ways to compose a photograph. To use these methods, you will need to train yourself to see your subjects in terms of lines and shapes. Sometimes lines in a photograph are obvious, like the horizon in a sunset picture. Other times, the main lines in a photograph are not nearly so obvious. One way to see the main shapes in your photographs is by squinting your eyes until the image almost becomes a blur, then you’ll see any lines and shapes created by the shadows and light. This is a great way to look at a scene when you’re thinking about how to compose a photograph. You may notice how shadows blend together in a way that might not be immediately obvious otherwise, creating shapes and forms that the viewer may not consciously notice when looking at a photograph, but that will definitely impact their perception of the image, nonetheless. Composition: Rule of thirds The rule of thirds sometimes know as the golden mean. The Rule Of Thirds & The Golden Mean One of the most commonly talkedabout rules in photography is the rule of thirds. The concept is best explained by taking your canvas and dividing it up into thirds, both vertically and horizontally, so that you essentially wind up with a tic-tac-toe board. The rule of thirds should be used as a guideline for when you have vertical or horizontal lines in your image. You will probably hear more about this photographic “rule” than any other, so I’ll explain it fairly in depth here and try to give you an understanding of why it is so effective. The rule of thirds is 8 derived from another rule called the “Golden Mean” that says that the main subjects of an image should be placed at the intersecting points created [roughly] by the lines mentioned above, thusly: So if you are composing a photograph of a sunset, try placing that horizon line one-third of the way from the top or bottom of your image, to include either more foreground or more sky. You’ll notice a stronger landscape this way. I’ll interject a little art history and math lesson here to explain the theory behind the Golden Mean. The Golden Mean is a number sort of like Pi, from your high school days in math class. Whereas Pi is equal to 3.14-yadda-yadda-yadda [math was never my best subject] and is handy for all sorts of geometrical things, the Golden Mean is equal to 1.618-yaddayadda-yadda. Mathematicians use the Greek letter Phi when they’re talking about the Golden Mean. This is derived from something else you may or may not remember from your math days called the Fibonacci Series. Fibonacci was an Italian mathematician born around 1170 A.D. who, for reasons unbeknownst to me [What really possesses mathematicians to do anything, I wonder? Maybe the same thing that makes us take pictures?], decided one day to start with the numbers zero and one and add them together. Okay, that just gave him the number one again. Big deal. Then what? Then he added the last number he used [one] to his new resulting number [one] and got two. He did it again by adding one and two and got three. Then next time... Well, let me just lay it out this way, it’s easier to visualise: 0+1 = 1 1+1 = 2 1+2 = 3 2+3 = 5 3+5 = 8 5+8 = 13 8+13 = 21 13+21 = 34 21+34 = 55 34+55 = 89 55+89 = 144 89+144 = 233 144+233 = 377 233+377 = 610 And you can keep going like that forever. All right. What does that prove? Nothing, as far as I can tell. BUT, if you take the ratios created by these numbers, an interesting pattern appears. [I promise, this is all going to get back to photography... just keep reading...] Ratio = 1 to 0 = 0 Ratio = 1 to 1 = 1 Ratio = 2 to 1 = 2 Ratio = 3 to 2 = 1.5 Ratio = 5 to 3 = 1.6666 Ratio = 8 to 5 = 1.6 Ratio = 13 to 8 = 1.625 Ratio = 21 to13 = 1.61538 Ratio = 34 to 21 = 1.61538 Ratio = 55 to 34 = 1.61764 Ratio = 89 to 55 = 1.6181 Ratio = 144 to 89 = 1.6179 Ratio = 233 to 144 = 1.6180 Ratio = 377 to 233 = 1.6180 Okay - whew! - the boring part is mostly over. Now we’ll talk about what this actually means in the world of taking pictures. Let’s look at this diagram below. If you look at the grey lines in the image, they make up squares. When all of these squares are put together in the way they make up this picture, they come together to form a rectangle. The ratio of the squares in this rectangle is composed of our magic number, 1.618! Here’s where it actually gets interesting. If you’ve hung on this long, I commend you. This ratio is found all over in the natural world. Have you ever seen a nautilus seashell that’s been sawed open? Its growth rate follows the curve in this image, 1.618 - exactly. Same with the little spirals that compose the interior pattern of a sunflower, where the seeds are. Leonardo DaVinci based all sorts of his artwork, experiments and theories on the Golden Mean. The vast majority of flowers have petals that number 3, 5, 8, 13, 21, 34, 55 or even 89. Even symphonies by Mozart and Beethoven can be broken down into this ratio whether that was on purpose or coincidental is anyone’s guess. Mozart is rumoured to have been a hobbyist mathematician. A study was done a few years back on top fashion models. Their faces, interestingly enough, have a number of characteristics with exactly the ratio 1.618. These numbers are everywhere in nature, and on some basic, instinctive level, the human eye tends to find beauty in things that correspond with this ratio. So that tells us where the idea behind the rule of thirds came from. Technically, if you draw grid marks on your frame and break it up into eighths, then draw your dividing lines down at the mark of three eighths on each side, you’ve got the spots where the Golden Mean hits. However, when you’re looking through your viewfinder, it’s not like you’re going to get out your tape measure and divide everything into eighths, hence we use the rule of thirds, which is very close for all practical purposes. Point of View. The last thing we’ll talk about in this lesson is point of view. Specifically, your point of view, as the photographer. How many times have you seen something worth taking a photo of - maybe a barn, a tree, or your dog - and picked up your camera to snap a picture right then and there? If this is the way you go about taking photos, you can dramatically improve your technique with one simple 9 process. Walk around the subject. All the way around it. See how the background changes as you move 360 degrees around your subject. Then lie down on the ground and point the camera up at your subject. Okay, if it’s your dog, you might have to watch out so he doesn’t come over and lick the camera lens, but you get the point. Climb a ladder and look down, trying the same thing. Tilt the camera vertically, even diagonally. Take a whole roll of film [or fill a whole memory card if you use a digital camera] of the same subject from drastically different points of view and compare the results. You might surprise yourself. You’ll definitely surprise the viewer by trying something different and that will add impact to your photo. When you’re walking around your subject finding different points of view, watch out for what is in the background. Not “Barbie the distracting element” that we already covered, but if you’re taking a photo of your Aunt Sally sitting in the back yard knitting a sweater, watch out for that tree behind her. Many a photo has been ruined because Aunt Sally’s hair is the same color as the tree bark and when you’ve taken the pictures and are looking at the final product, you notice that it actually appears as if that tree branch is growing out of her head! The trick is to look - really look through that viewfinder before you snap the shutter. Make sure every single element is something you want in the photograph and that each element is in the exact spot that you want it.

Aperture, Camera to subject distance , Type of lens, Point of focus. Aperture The smaller the aperture the greater the depth of field Therefore, f2.8 gives less depth of field than f22 Some uses for these are shallow DOF for portraits and deep DOF for landscapes, this is not a RULE rather a beginning point. Camera to Subject Distance The closer the camera is to the subject the lower the DOF even at f22 Type of Lens The wider angle the lens the greater the DOF, [Wide Angle], Wide = shorter than “Normal“ The narrower the lens the shallower the DOF [Telephoto or Zoom]. Narrower =longer than “normal.“ Point of focus The closer the point of focus the shallower the D.O.F, Focusing on someone’s nose in a portrait at f2.8 may leave the eyes out of focus, it’s better to always focus on what you want in focus to achieve the correct focus. References:Horenstein, “Beyond Basic Photography” page 50, 221-225 Langford, “Basic Photography” page 178 Depth Of Field Control & Lenses Depth of field Distance between the nearest and furthest parts of a subject which can be imaged in acceptably sharp focus at one setting of the lens. Short focal length lenses. Also called wide-angle lenses, run from super-wide 15mm and fish-eye types, through 21mm, 24mm, 28mm and 35mm. Different manufacturers make some or all of the above focal lengths for their own cameras, or a variety of S.L.R’s. If you cannot get all of those listed for your brand of camera, don’t worry, they are so similar that 21mm or 24mm lenses are nearly interchangeable for practical use. Medium focal length lenses. These include the so-called normal range from 50mm through 55mm The normal label is applied when the focal length of the lens is close to the diagonal of the image area on the negative. 35mm negs are about 2" on the diagonal - approximately 50mm. This is considered a pleasant medium focal length for this picture size. Long focal length lenses. Also called telephoto lenses, begin about 85mm and run to 200mm, 300mm and as long as a strong man [person, photographer], is able to lift without a block and tackle. The importance of focal length for depth of field. Knowing that a wide-angle lens will give you more d.o.f. at any aperture than a telephoto lens will at the same aperture and from the same camerato-subject distance, you begin to conceive where and why certain lenses are more useful than others. In crowds, in small rooms or any tight space, or for more inherent d.o.f. when shooting a scene or still life, choose a wide-angle lens. Even without being stopped down to f16 the smallest opening on most S.L.R lenses [except for the macro close-up type], you get good to fantastic d.o.f. with 21mm, 24mm, 28mm and 35mm lenses. In situations where you want relatively shallow d.o.f. such as a portrait with an out-of-focus background, choose a medium or long focal length lens, and shoot at medium or large apertures. With experience you learn that a 135mm lens at f11 from a distance of about 5 feet will give you a nice sharp image of someone, but distracting objects behind the person appear softly focused. Of course, when you need the magnifying power of a telephoto lens, especially if you can’t move closer to a subject, there is no substitute for 135mm or longer. After about 200mm, S.L.R lenses tend to become pretty heavy and bulky to tote around casually, but these types are all sold with their own cases and shoulder straps to make them more comfortably portable. Focusing distance The closer you focus on any scene or object the less d.o.f. a lens produces at a given aperture and focal length. In reverse, as a camera to focusing point distance increases, d.o.f. also expands. Suppose you focus at 1.5 meters with a 50mm lens set at f8. d.o.f. is only about 50 cm from 1 metre to 1.5 meters”. Now move back to 3 meters and focus on the same subject. With the lens opening still at f8 d.o.f. has increased to more than 2.5 meters. Knowing about d.o.f. and how to control it helps you choose where you will place your camera, which lens will be most effective for a particular subject, and what lens opening will be feasible for the d.o.f. needed to accomplish the photographic feat you’re tackling. If you think in meters, you’ll be pleased to note the d.o.f. markings are in meters as well as feet. D.O.F. seems to be one of the least understood principles of photography, but it is neither tricky nor mysterious. Being able to control it gives you a lot more mastery of images than you could hope for with a less sophisticated camera. It becomes easy to visualise how much of a picture will be sharp. If you shoot a distant scene focused at or near infinity, you’ll have complete sharpness at any aperture if nothing is closer to your lens than about 100 feet. If you shoot a face in a crowd and want selective focus [or selective out-of-focus ] you’ll use a fairly large lens opening, depending on your distance to the person. This will blur the background so it is noncompetitive with the main visual interest. Hyperfocal Distance. When a lens is focused at infinity, the near limit of d.o.f. is called the “Hyperfocal” distance for that particular aperture [it will vary with each aperture setting as you have already experienced in the previous section on “Aperture”. In lens A aperture is f8 and lens is focused at infinity – d.o.f extends from 7 meters to infinity. However for maximum d.o.f., that is a greater hyper-focal distance, should set the distance scale so that the infinity mark lines up opposite your f-stop on the d.of. scale [see Lens B]. Now with lens still set to f8, d.o.f., extends from 3 1/4 meters to infinity, that is, everything from 3 1/4 meters to infinity will be sharp. Greatest hyper-focal distance is obtained by setting infinity at the smallest apertures - and even greater on a wide angle lens. Remember you set infinity to the f stop not the focusing mark on the d.o.f. scale. this is an effective method of getting in in focus both the foreground and background of a scene that extends to the far distance. Similarly you can pre-set a smaller distance on lens to a particular f-stop, to get a narrow area in focus. This is particularly effective when you don’t have time to focus. 13 Lenses & Lens Characteristics let pass when it is open to its widest aperture. Just as a large window allows much light into a room, a large lens opening allows much light into the camera. Smaller windows, like smaller lenses, allow less light to pass. The speed of a lens is expressed by the symbol f/-, such as f/2.8 or f/2.0. The more light the lens allows to pass, the “faster” the lens. Key concepts: Focal length [F], focal point, object at infinity, negative format, normal lens, telephoto lens, wide-angle lens, speed f/-, maximum aperture, f/=F/d Two major characteristics of the camera lens are its speed and its focal length. The focal length [F] of a lens is the distance between the lens and the focal point where a sharp image of an object at infinity is formed. Have you ever used a magnifying glass to focus an image of the sun on a piece of paper or a leaf? The focal length of the magnifying glass is the distance between the glass and the image of the sun when it is in sharp focus. The sun, of course, is very far away and we may consider it an object at infinity. Practically speaking, we may consider any object more than 15 meters away from the lens an object at infinity. You do not have to measure the focal length of a lens - the manufacturer inscribes this information of the lens barrel. The focal length of most lenses never changes because it is a characteristic of the design to which the lens is ground. [Zoom lenses are an exception - their focal length is variable and can be adjusted as needed]. Normally a camera is fitted with a lens having a focal length approximating the diagonal of the negative format used in that camera. Thus the normal lens for a camera using a 6 cm by 6 cm negative format would be approximately 8cm. The normal lens for a 35mm camera using a 24mm by 36mm film format would be approximately 43mm. Actually, the f/value of the lens is a precise way of expressing the relationship between the diameter [d] of the lens at its maximum aperture and the focal length [F] of the lens. The f/value of the lens is calculated as follows: focal length diameter of lens d = f stop Any given f/value defines an exact relationship between the lens aperture and the area of the negative format no matter what camera or lens is in use. The system of f/values provides a common standard of light measurement for all cameras under all conditions. The diagram above shows shows how this was calculated using the formula for finding the diagonal of a rectangle. Longer-than-normal length lenses are commonly known as telephoto lenses; their use will increase the image size on the negative. The effect is similar to looking at an object through a telescope. Lenses with shorter-thannormal focal length are known as wide-angle lenses; their use will reduce the image size on the negative. The effect is that more peripheral details are included in the picture at any given distance. Lenses with longer or shorter focal lengths also have differing angles of view. That is, they see less or more of the peripheral details in a scene than a normal lens at the same distance. Figure 2-2, below, shows the different angles of view associated with lenses of differing focal lengths. The second major characteristic of a lens is its speed. The speed of a lens expresses how much light the lens will The manufacturer inscribes the f/value on the barrel of the lens. An f/2.0. lens has a diameter that measures one half of its focal length, an f/4.0 lens has a diameter one fourth of its focal length, 14 and so on. The greater the diameter of the lens, the more light that can pass through it at its widest aperture. Thus larger diameter lenses for any given focal length are faster lenses; f/2.0. is faster than f/ 4.0 is faster than f/5.6 and so on Another diagram showing the differences in angle of view from many lenses on a 35mm film camera. 15 How Images Are Formed Pinhole Images When light reflects off a subject and passes through a pinhole, it forms an upside down image on a surface placed behind the pin hole. The light which reflects off the bottom of the subject passes through the pinhole and continues in a straight line to the top of the material placed behind the pinhole. The size of the pinhole determines how much sharpness there is in the image that is formed. The distance of the light sensitive material to the pinhole determines the size and angle of view of the image. A pinhole creates images with very small circles of light, which directly relate to the size of the pinhole. The resulting image is not formed by points of light, as it would be with a lens, therefore it has low sharpness which is equal from foreground to background [unlimited depth of field]. Small pinholes also have low image brightness resulting in long exposures. Refraction Light slows when passing from air to glass and slows even more when passing from air to water. If the light is traveling at an angle to the surface of the denser material it slows unevenly. The side of the light wave which hits the material first drags and alters the direction of the light. Resolving power Resolving power is the ability of an image - formation process, [i.e. camera lens, enlarging lens, printing materials etc ] to individually or in combination reproduce a test graphic [see diagram to the left] so that individual elements of the image can be seen distinctly. Targets used to measure resolving power have alternating light and dark lines at varying distances and widths. USAF and ANSI resolution targets are in the form of parallel bars forming a spiral. These bars decrease in size and increase in line frequency the closer they are to the centre. The RIT target is alphanumeric. The smallest set of numbers must be correctly identified to be correctly resolved. To test the resolving power of a lens, a target is placed on the lens axis at the specified distance [for example 21 times the focal length] to produce an image at a specified scale of reproduction. The image is viewed with a magnifier, a target is chosen, where the finest set of elements can be seen distinctly. This has a specific reference to lines/mm. Dispersion Refraction bends shorter wavelengths slightly more than longer wavelengths, creating dispersion of white light into an array of colours. Diffraction Stopping down [making the aperture smaller] increases the diffraction of light, which reduces image sharpness, outlines of objects become less defined. When the aperture is so small light hits the sides of the aperture and bounces outwards instead of in a straight line when it leaves the other side. It is because light travels in waves, that the wave edge hits the aperture and bows out. Resolving power values are based on an 8x10 print viewed at a distance of 10 inches. Minimum acceptable resolving power is 10 lines/mm. A lens stopped down to f64, has maximum resolving power of 28 lines/mm which is acceptable for an 8x10 neg because it doesn’t have to be blown up. But a 35 mm negative would have to be blown up 8 times to make an 8x10 print. Therefore if a 35 mm camera were closed down to f64 it would produce on the neg 28lines/mm, but blowing it up 8 times, for an 8x10 print, would divide that diffraction-resolving power by 8 resulting in3.5 lines/mm, which is unacceptable. F16 produces 112lines/ mm which when divided by 8 results in14lines/mm. This is why lenses for 35 mm cameras are not usually calibrated for smaller apertures other than f22 [which gives 10lines/mm]. 16 Exposure. What is exposure? The Macquarie dictionary defines exposure as:“the act of presenting a sensitive material to the action of light ”1 This definition does not offer us much at all? If we were simply to present our light sensitive material to light. We would have an out of focus black slab of exposed negative. We need to use devices such as lenses and light meters to produce an image! In fact an image can be made with out a light meter and lens, a pinhole and an estimate can be made, but we are now beyond this guesswork approach at photography and now should be aiming for the best exposure in any given situation. This can be achieved by the correct use of a light meter, the artistic choice of lenses appropriate the the desired or pre-visualised results. I would like to add the word measured to the above definition. Therefore the the dictionary definition reads, the act of presenting a sensitive material to a measured action of light. Measurement now enables some level of control over the final appearance of the negative which will then produce a reasonable print. To achieve this measurement we need some means of calculating the light levels around us. How do we measure exposure? Most photographers will use a light meter.There are two main types of light meter used today, reflective and incident. The reflective light meter measures the light reflected back from the subject and the incident measures the light falling on the subject. There are many light meters available on the market today but all have one thing in common, they measure light and give it a value that then is translated back into a useful shutter speed and aperture combination. What is this value? This value is a tone called middle grey. Middle grey because it resides in the middle between the two extremes of highlight and shadow. All light meters read for middle grey. Why aren’t all our pictures all grey then? So when we point a light meter at an object regardless of its colour, the light meter tells us to give it enough exposure to produce a grey photograph [ with black and white film]. As most situations have a mixture of tones, trees skin clothes of different colours, etc these items reflect different amounts of light. So the film receives more or less light depending on it’s colour, as indicated by the light meter in the camera. Who controls who? What happens when we present a scene to the camera that does not have a mixture of tones, with in it? It is likely that we will end up with a grey photograph. Fine if we are photographing a grey object, not so if it is something else. One way to measure a scene effectively is to get as close as possible to the subject and take a reading off it. This method works well when the person/subject is in shadow, for example. [ ie day or night ] Film sensitivity/speed Aperture Shutter speed As we can not control the quantity of light [ day or night ], we are left to the ISO, aperture and shutter to control the amount of light striking the film, guided by the light meter.1 This is called the exposure triangle. Where can I find more? Try these references, “Black & White Photography, a basic manual” chap 5 pg 43 by Henry Horenstein pub by Little Brown & company “Basic Photography”,chap 10, pg 186 by Michael Langford, pub by Focal press “The Negative” chap 3, pg 29 What other aspects of exposure do I need to consider? Alls well and fine but what about other things like movement, and Depth of Field? Each exposure setting given by the camera has an equivalent setting that will let in an equal amount of light. For example, f2.8 @ 1/500 is equal to f16 @ 1/15 of a second. The final choice then is either amount of depth of field, or the amount of movement in the shot, that you want. So how do I get it all to work? Exposure is tied in to several factors. Quantity of light 17 Aperture and Image Brightness Relationship between Aperture and Image Brightness. The Aperture is the opening in a lens which allows light to pass through to the film plane in the camera body. It controls the amount of light reaching the film thus enabling a correct exposure to be made under different lighting conditions. The aperture is made up of a moving diaphragm, in the form of a series of overlapping leaves, usually black metal blades. The diaphragm is usually controlled by a ring on the lens barrel. Turning the ring allows the aperture to be opened or closed from full open diameter to the smallest circular opening. Because the aperture is in the middle of the lens it dims or brightens the light from the image evenly. Different sized apertures are indicated by f numbers, also known as f stops. These are marked on the side of the lens. F numbers are an internationally agreed upon geometric sequence of numbers indicating the amount of light passing through the aperture. Each f number progressively double s or halves the amount of light reaching the film. the effective aperture. [ ratio of aperture to focal length ] Effective aperture is the diameter of the light beam that files the open diaphragm of the lens, [ maximum aperture ]. The effective aperture is slightly smaller then the real aperture because the diaphragm is usually positioned behind the very front of the lens and light is converged from the front lens element through the diaphragm. Because the aperture changes proportionally to the focal length of the lens, the same f stop will give the same exposure with different lenses that are focused on the same subject. For example: f4, lets in the same amount of light in a 100 mm and 50 mm lens. f4, is 1/4 the focal length of each lens. In a 100 mm lens the effective aperture is 25 mm f4 = 100/25 In a 50 mm lens the effective aperture is 12.5mm f4 = 50/12.5 The series of apertures on most cameras is: f 1.4, f 1.8, f 2.0, f 2.8, f4, f 5.6, f8, f11, f16, f22. Other cameras or lenses may also have f1, f 32, f64. Larger f stop numbers represent smaller apertures and smaller f stops represent larger apertures. As you stop down - increase numbers - you let more light in. Thus the amount of light passing through the aperture doubles as the aperture increases or halves as it gets smaller. For example, f 5.6, lets twice as much light through as f8, f16 lets half as much light through as f11, and 1/4 as much light as f8. The f number is the same as the relative aperture and is calculated by dividing the focal length of the lens by 18 Exposure & Light Meters. Exposure The function of exposure calculation is considered the most important function that you will have to carry out after you have visualised the image you are seeking. This visualisation is the concept of projecting the final image that you are creating in your mind, prior to carrying out any practical action to achieve this. You must be capable of assessing the tonal range presented to you and be able to measure accurately the reflectance values. type] that control the function of obtaining a correct exposure are the film speed, the aperture and the shutter speed. To become a competent operator of your equipment and not a slave to it, you should learn the f numbers on your aperture ring and the settings on your shutter dial. speed range, hence an exposure setting of: f4 at 1/60 = f8 at 1/15. How Aperture & Shutter Speeds Combine. Most photographers tend to use the dial calculator that is situated on the meter. With built in meters [T.T.L] there is no scale, only the ability to match both aperture and shutter speed to achieve the correct reading or setting of the meter in the camera. Therefore to achieve a print to the correct tones that you have visualised you will need to know what zone the tone falls into, which is called making zone adjustments. One method which is used to control the required tonal values is to use the ‘Middle Grey’ reading method. Take a selected light reading from a neutral test card to give you a correct reading for a mid grey value under the prevailing light conditions. However, if there are highlight areas and low light areas falling on the subject it will make it impossible to achieve a balanced exposure for all the areas of the scene being photographed. Another method used to achieve a balance of tonal range in your exposure is called “Averaging high and low values”. This is achieved by taking readings on the highlight areas and the low light areas and to then average the readings and take the middle scale to set your exposure. A final method which can be used, is to take a spot reading of the area of importance in your visualisation and to then place this into the appropriate zone, and leave all the remaining values to fall into their own zones, whatever they may be after processing and printing. As already mentioned, the settings on your camera [T.T.L Shutter Speed Range - expressed in fractions of a second. B, 1, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1000, 2000. “B” is reminiscent of when photographers used a round rubber air filled BULB to trigger the shutter. Most exposures were well in excess of one second duration. Hence “B” is used for long exposures where the shutter is required to be held open. This is done by either by keeping the finger on the shutter release or by using a cable release with a locking device which keeps the shutter release locked down. Lens Aperture Range [Pentax K1000, 50mm lens]. Apertures are expressed in terms of f stops. f2, 2.8, 4, 5.6, 8, 11, 16, 22. Exposure is controlled by a combination of shutter speed and aperture selection on the camera, according to the particular film speed being used. The number of units of light for each change in f stops doubles as the aperture increases or halves as it gets smaller. There is a direct relationship of this to the shutter 19 Exposure and Action [ Movement]. Very fast shutter speeds normally are thought necessary to stop or freeze the action of a fast-moving subject. Yet you don’t need a camera with a shutter speed of 1/1000 second to take good action photographs. You’ll bring home good action shots if you understand a few basics about speed, light, film and camera techniques. Speed is relative. Three factors affect the apparent speed of your subject:[1] the speed of the subject itself, [2] the distance between the subject and the camera, and [3] the angle of movement relative to the camera’s axis. Obviously you will need a faster shutter speed to stop or freeze the action of a speeding racing car or a football player streaking for the goal line than you will need for a person walking slowly down the street. To freeze the action of a moving subject, the shutter must open and close again before the image of the subject perceptibly changes position on the film. Consequently, normally we require faster shutter speeds to stop the action of faster-moving subjects. The camera-to-subject distance. As you stand by the highway watching speeding cars go by, you may observe them to zoom rapidly past you. But move back from the edge of the highway one hundred feet or so, and the apparent speed of the cars is considerably less. On the horizon, speeding cars may appear to be moving hardly at all. Translated into shutter settings, a general guideline for this effect might state: The closer the camera is to the moving object, the faster the shutter setting needed to stop or freeze it apparent movement. photograph a moving object moving more directly toward you than across your line of vision, and its action can be stopped with a slower shutter speed. Stopping fast-moving action most often does require fast shutter speeds, but fast shutter speeds in turn require larger aperture settings to maintain equivalent exposure. You will recall that large apertures decrease depth of field. Thus obtaining great depth of field tends to pose a problem in action photography as in any situation requiring a fast shutter. How Can You Use Both A Fast Shutter And A Small Aperture? One way is to select a faster film. As film speed is increased, the amount of exposure required is reduced, permitting the use of smaller apertures with your fast shutter setting. Another way is to use some form of supplementary lighting, such as flash or strobe. Additional light intensity also will permit smaller apertures with your fast shutter setting. Good action shots do not always require you to stop the action of your subject. You can enhance the sense of movement in your photography by using a slow shutter and deliberately blurring the movement of details. By using a very slow shutter and stationary camera, for example, you can make your fast moving subject appear blurred against a static background. Or you may choose to use another slow shutter technique known as panning. In panning, use your eyelevel viewfinder and spot your subject as it moves into view. Then pivot your head and shoulders so that you keep the subject in the viewfinder at all times. When your subject is in correct view, release the shutter without interrupting your pivot. Be sure to follow through, just as you would in a tennis serve, after you snap the shutter. The trick is to have the camera moving at the same speed and in the same direction as the subject. The resulting photography will show your subject - car, motorcycle, runner, surfer - frozen in clear focus. The background and foreground, however, will be a mass of blurs and streaks caused by the camera’s movement during exposure. Panning gives a nice sense of speed and you will have stopped the subject’s movement with a relatively slow shutter speed. Panning works best at shutter speeds under 1/30sec. The angle of the subject’s movement relative to the axis of the camera. Once again, a car moving directly toward you may appear to be moving hardly at all, whereas the same car at the same distance moving across your line of vision may appear to be moving quite rapidly.

Advantages and disadvantages of spot centre-weighted matrix/pattern/ evaluative meters Choosing the right metering type (also called pattern or mode) to use, is important for correctly setting camera exposure. The wrong metering type (or using the right meter in the wrong way), can result in over or underexposed photos. Metering type or mode should not be confused with exposure mode (aperture-priority, shutter-priority). Metering refers to how the SLR's built-in light meter measures the light coming in from the lens (TTL: Through The Lens) and calculates a brightness value to send to the exposure mode computer. Centre-Weighted Metering In most photographs, the subject (usually people) is in the centre. If the background is lighter or darker than the subject, a simple averaging light meter will give the wrong brightness value. This is where centre-weighted meters come in. A centre circle carries more "weight" when the light meter averages out the brightness across the scene, to come up with one overall brightness value. For example the Nikon D90 has a selectable 6, 8 or 10mm diameter circle (on a 24 x 16mm sensor) that is weighted at 75%, while the rest of the frame compensation (or using manual exposure mode), even tricky lighting situations can be quickly and reliably handled. For many situations metering off the floor or other mid-toned (medium brightness) area, then locking the exposure (pressing the shutterrelease button halfway), results in accurate exposures: Backlight, where the sun is behind the person (aim the camera at the ground with the sun and sky completely out of the viewfinder, then lock the exposure). Very light or dark clothing (aim the camera at the floor: most carpets, tiles and wooden flooring will give the correct exposure). If a suitable surface cannot be found, the camera can be aimed to straddle the border between a light and a dark area. Like a spot meter, exposure compensation can also be used together with metering off very dark or light areas (clothing, snow). How to Use a Spot Meter A spot meter measures the brightness of a small circle in the centre of the viewfinder. For example the Nikon D90 uses a 3.5mm diameter circle in the centre of the frame, for 100% of the brightness measurement. The simplest way to use a spot meter is to measure a mid-toned area. Unlike a centre-weighted meter, something as small as a person's face can be used. The disadvantage is that moving the camera a bit can cause a large change in the brightness reading. This makes the spot meter unsuitable for quick exposures. Like a centre-weighted meter, a spot meter can also be used to meter white clothing or snow (add +2 exposure compensation) or dark clothing (add -2 exposure compensation). Matrix (Nikon) or Pattern/Evaluative (Canon) Metering. Today's computerised DSLRs use smart light meters that try to add a professional photographer's judgment: The brightness and color of many different areas of the scene (10 to 100, often more) is measured individually. This pattern is compared ("evaluated") against a database of thousands of professionally exposed photographs, which also contains information on any exposure compensation used. Based on the closest match, an adjusted brightness value is output. This is supposed to handle tricky lighting situations such as backlight, snow, black clothing, candlelight etc. However, the results won't be perfect. Intelligent use of centre-weighted and spot meters will give more consistently good results. Let's say a photographer wants to photograph a man sitting in the shadow of a doorway, with a sunlit garden in the background (assume no flash is to be used): Portrait photographers will expose for the man and over-expose the garden. Landscape photographers will expose for the garden and leave the man in shadow, because we don't see overexposed areas in real life. Depending on the photographer, either solution can be correct. The matrix meter will choose one solution, which may or may not be what the photographer wants. The photographer can aim-off and use exposure-lock to choose the area to expose for, but that's just forcing the matrix meter to act like a centreweighted meter. contributes only 25% of the final brightness reading. It is a good default, general purpose mode to use for both beginners and professional photographers. By aiming-off and using exposure lock and 23 Metering modes, [Exercise] Exercise 3 Pair up with another student, use a camera on a tripod, take portraits of each other under varying lighting conditions. For example, find a place where you can stand in the full sun, make a portrait, with the sun, Behind you, with the camera in, spot, centre-weighted, matrix/pattern/ evaluative metering mode. [3 pictures] Behind the subject, with the camera in, spot, centre-weighted, matrix/ pattern/evaluative metering mode.

Download the 24 images to a computer in the computer lab and examine the differences. Write up a report on your conclusions, ask yourself, which ones look the way you expected, which ones look incorrect, are there some pictures where the differences are minute and some where the differences are large? Is there one general method of metering that covers all situations? Make a proof sheet using bridge. ISO/Noise Exercise 5 Indoors, at night, using a tripod set up a scene or a portrait using only the available light, set the ISO on your DSLR to it’s lowest, either, 50, 100, or 200 ISO, and your camera to manual mode.

These are best described as aesthetic controls, as opposed to all the technical issues we’ve looked at so far. Depth of Field or DOF, is best described as; Distance between the nearest and furthest parts of a subject which can be imaged in acceptably sharp focus at one setting of the lens. About DOF Part I DOF Part II Movement Depth of field is governed by 4 factors 1. Aperture 2. Camera to subject distance 3. Type of lens 4. Point of focus. Aperture The smaller the aperture the greater the depth of field Therefore, f2.8 gives less depth of field than f22 Some uses for these are shallow DOF for portraits and deep DOF for landscapes, this is not a RULE rather a beginning point. Camera to Subject Distance The closer the camera is to the subject the lower the DOF even at f22 Type of Lens The wider angle the lens the greater the DOF, [Wide Angle], Wide = shorter than “Normal“ The narrower the lens the shallower the DOF [Telephoto or Zoom]. Narrower =longer than “normal.“ Point of focus The closer the point of focus the shallower the D.O.F, Focusing on someone’s nose in a portrait at f2.8 may leave the eyes out of focus, it’s better to always focus on what you want in focus to achieve the correct focus. Short focal length lenses. Also called wide-angle lenses, these lenses run from super-wide 15mm and fish-eye types, through 21mm, 24mm, 28mm and 35mm. Different manufacturers make some or all of the above focal lengths for their own cameras, or a variety of S.L.R’s. If you cannot get all of those listed for your brand of camera, don’t worry, they are so similar that 21mm or 24mm lenses are nearly interchangeable for practical use. Medium focal length lenses. These include the so-called normal range from 50mm through 55mm, this is an analogue film camera’s diagonal measurement of the film, in digital it varies on camera models but is usually, 32~38mm. The normal label is applied when the focal length of the lens is close to the diagonal of the image area on the negative. There 35mm negs are approximately 50mm across the diagonal, the sizes varies on digital cameras. This is considered a pleasant medium focal length for this picture size. Long focal length lenses. Also called telephoto lenses, begin about 85mm and run to 200mm, 300mm and as long as a strong person/photographer, is able to lift without a block and tackle. The importance of focal length for depth of field. Knowing that a wide angle lens will give you more d.o.f. At any aperture than a telephoto lens will at the same aperture and from the same camera to subject distance, you begin to conceive where and why certain lenses are more useful than others. In crowds, in small rooms or any tight space, or for more inherent d.o.f. when shooting a scene or still life, choose a wide-angle lens. Even without being stopped down to f16 the smallest opening on most S.L.R lenses [except for the macro close-up type], you get good to fantastic d.o.f. with 21mm, 24mm, 28mm and 35mm lenses. In situations where you want relatively shallow d.o.f. such as a portrait with an out-of focus background, choose a medium or long focal length lens, and shoot at medium or large apertures. With experience you learn that a 135mm lens at f11 from a distance of about 5 feet will give you a nice sharp image of someone, but distracting objects behind the person appear softly focused. Of course, when you need the magnifying power of a telephoto lens, especially if you can’t move closer to a subject, there is no substitute for 135mm or longer. After about 200mm, S.L.R lenses tend to become pretty heavy and bulky to tote around casually, but these types are all sold with their own cases and shoulder straps to make them more comfortably portable. Focusing distance The closer you focus on any scene or object the less d.o.f. a lens produces at a given aperture and focal length. In reverse, as a camera to focusing point distance increases, d.o.f. also expands. Suppose you focus at 1.5 meters with a 50mm lens set at f8. d.o.f. is only about 50 cm from 1 metre to 1.5 meters”. Now move back to 3 meters and focus on the same subject. With the lens opening still at f8 d.o.f. has increased to more than 2.5 meters. Knowing about d.o.f. and how to control it helps you choose where you will place your camera, which lens will be most effective for a particular subject, and what lens opening will be feasible for the d.o.f. needed to accomplish the photographic feat you’re tackling. If you think in meters, you’ll be pleased to note the d.o.f. markings are in meters as well as feet. D.O.F. seems to be one of the least understood principles of photography, but it is neither tricky nor mysterious. Being able to control it gives you a lot more mastery of images than you could hope for with a less sophisticated camera. It becomes easy to visualise how much of a picture will be sharp. If you shoot a distant scene focused at or near infinity, you’ll have complete sharpness at any aperture if nothing is closer to your lens than about 100 feet. If you shoot a face in a crowd and want selective focus [or selective out-of-focus ] you’ll use a fairly large lens opening, depending on your distance to the person. This will blur the background so it is noncompetitive with the main visual interest. Hyper-focal Distance. When a lens is focused at infinity, the near limit of d.o.f. is called the “Hyperfocal” distance for that particular aperture [it will vary with each aperture setting as you have already experienced in the previous section on “Aperture”. In lens A aperture is ƒ8 and lens is focused at infinity – d.o.f extends from 7 meters to infinity. However for maximum d.o.f., that is a greater hyper-focal distance, should set the distance scale so that the infinity mark lines up opposite your ƒ-stop on the d.of. scale [see Lens B]. Now with lens still set to f8, d.o.f., extends from 3 1/4 meters to infinity, that is, everything from 3 1/4 meters to infinity will be sharp. Greatest hyper-focal distance is obtained by setting infinity at the Left a lens using hyper-focal distance, right a lens focused on infinity. smallest apertures - and even greater on a wide angle lens. Remember you set infinity to the ƒ stop not the focusing mark on the d.o.f. scale. This is an effective method of getting in in focus both the foreground and background of a scene that extends to the far distance. Similarly you can pre-set a smaller distance on lens to a particular ƒ-stop, to get a narrow area in focus. This is particularly effective when you don’t have time to focus. The lens on the left has a grater amount of DOF extending from almost 3 meters to infinity. The lens on the right only has a DOF from, 7 meters to infinity.

AV mode should also be selected on the mode dial at the top of your camera. Auto White balance is fine, however you may wish to manually select an appropriate WB setting according to the lighting conditions outside. Attach your camera to a tripod. Photograph some traffic moving across your viewfinder at a constant speed. Compose your image and focus on the point that the car will be passing. THEN experiment with panning. Then in Av Mode, choose the smallest aperture on your camera, usually ƒ 16 or ƒ 22. Your camera will automatically select an appropriate shutter speed to balance the exposure. PART TWO Use the same settings as in Part one. 1. Set up your tripod on a freeway overpass/ foot-bridge. 2. Then in Av Mode, choose the smallest aperture on your camera, usually ƒ 16 or ƒ 22, with your camera. When it is directly in front of you, press the shutter release button. Change your aperture by one stop, to ƒ 11 or ƒ 16, and take the same photo. 6. Keep going until you run out of apertures. Set your camera to Shutter Speed Priority Mode. (TV) Select 1/30 second.

The latent image is created by the camera or enlarger, and the action of that exposure is amplified/ developer change the exposed silver halides to metallic silver. The factors controlling the action of the developer "From its inception up to the present, photography has depended mainly on the response of silver compounds to light. With some exceptions, the effect of light has been to produce a converted by the development process.What is the difference between a latent image and a visible image? A latent image is the image formed on on the latent image are:- latent image on a light-sensitive surface that usually consists of an emulsion of one or more silver halides in gelatin. This image is made visible as the result of chemical process the film or paper by the action of exposure of light to the film or paper. This image stays invisible until the action of a developer is applied to the negative or paper. After the action of known as development. developer the image becomes visible. When a silver halide emulsion on film or paper has been exposed to a light image, a latent image is formed in the How does a developer contribute to the formation of an image? The developer chemically converts the emulsion; in most circumstances this image would not be visible because of the small amount of silver produced.The development process amplifies this image by a factor of up latent image into the visible image by a process called reduction. For a more thorough explanation of the concepts and principles of reduction see:"Photographic Materials and Processes" Stroebel, Compton, Current, Zakia pg 240. to 10 to the power of 9, producing the final silver image."† From the above we can see that development is a crucial factor in the What happens when we add developer? Reduction is a process where the production of silver photographic action of several components of the ◦ ◦ ◦ Time. Temperature. Type of developer.These three factors, affect the end result of the quality of the image. Time. The longer the image is in the developer the denser the highlights. For a negative this means an incrrease in contrast and in the case of the prints a lowering of contrast. Temperature. The activity of the developer is governed by its temperature. This activity increases as the developer gets hotter and decreases as it gets colder. Therefore a consistent approach to development temperature is required. Generally 20 degrees celsius is chosen as a bench mark. Any deviations from this will require an increase or decrease in time. Type of developer. Each developer on the market has it's own inherent characteristics that affect the development of the latent image. These characteristics can range from issues such as contrast, speed. In the case of negatives grain and in the case of prints print colour and tonality are modified by the type of developer used. The individual components of a developer and their proportion to each other are what make a developer work they way they do. There are many texts available that discuss this in depth, see the bibliography for further info. It is therefore important to develop ( no pun intended ) a consistent system of development that is controlled in all these areas. Processing B&W film The Chemicals Film Developer: The function of the developer is to change each exposed silver halide grain which is suspended in the emulsion into a black, metallic silver grain without significantly changing the unexposed grains. Many of these grains of black metallic silver together make up the image. Stop Bath: The stop bath immediately stops the action of the developer and neutralises the film in readiness for the fixer. Film Fix: The fixer makes the image permanent by changing the unexposed silver grains [which were therefore not changed to black metallic silver] into a soluble silver salt which is later removed in running water. This means that only the black metallic silver grains remain in the emulsion. Steps For Developing Films [Part One] Rinse between fixing and HCA to clear some of the fixer 2 REEL TANK - 600 ml 5 REEL TANK - 1250 ml Hypo Clearing Agent - H.C.A.: This chemical removes much of the fixer from the film and is a water saving aid. The film now needs only a minimal wash in running water [about 10mins. ] and makes the negative more permanent. Organise ALL chemistry in advance. Then test the Fixer. Water: fill tank and dump for 20sec then 10 sec 5sec Photoflo - wetting agent: This enables the film to dry without spots or streaks. Fixer Test: This must be done each time you process film. Hold the ‘tail’ from your film in the jug of fixer and agitate until the film is clear. Note the time taken. Your correct fixing time is 3 times the clearing time. If the film takes longer than 3 minutes to clear, discard the fixer, which is becoming exhausted, and use fresh fixer. [Check with a staff member first]. If some opacity [milkiness] remains it is not fixed.

To use this chart multiply the published time at recommended ASA by the factor in parenthesis (ie. If Tri-X rated at 400ASA is normally developed for 6 mins in a standard soup, then when Tri-X is pushed three stops to 3200ASA development would be: 6 x 4.5 = 27 mins). Standard Developer 1 stop push = (x1.5) 2 stop push = (x2.25) 3 stop push = (x4.5) TMax Films 1 stop push = no change 2 stop push = (x1.33) 3 stop push = (x1.66) Compensating Developer 1 stop push = (x1.4) 2 stop push = (x1.85) 3 stop push = (x2.5) *Compensating developers include Microphen, TMax, and any other developers which are specifically formulated for push processing Please use these recommendations as starting points only. In many cases these times will prove excessive, but when all else fails they can be a good guideline. Please note separate data for Tmax films. 36 Darkroom procedure. Darkroom Etiquette. 1. Move quietly and slowly to avoid vibration. 12. After packing up, switch off power and remove enlarger plug. 2. First person/persons in set up darkroom and prepare chemicals. (Fill trays and re-fill containers). 13. Cover enlarger with protective cover/pillow case. 3. Clean bench top with damp sponge to remove dust. 4. Prepare equipment before switching on safelights. 5. Report damaged or missing equipment to teacher. 6. Wash out developer measurer before starting. 7. Replenish chemical stock when empty (performed by duty group). 8. Place tag on enlarger number before starting. 14. Cleaning up is the responsibility of all those working in the darkrooms. 15. Use your initiative at all times and help your fellow students. BE TIDY! 16. Do not leave print viewing trays near the print drier. They belong in the darkroom in their racks. Note : Work areas, darkrooms, studios, etc. May not be used outside your scheduled times. (See timetable) 9. Always agitate prints and move them along, do not leave them in trays. 10. Keep all paper (test strips also) in your black carry bag. 11. Do not leave paper exposed to safelight, it will fog. 37 Introduction To The Enlarger The enlarger operates like a slide projector mounted vertically on a column. A lamp shines light through the negative and is focused through a lens to expose the negative image on the printing paper: • Image size is determined by distance between the enlarger head and the paper. • Focus is determined by moving the lens closer or further from the negative. • Exposure is controlled by the timer and lens f stops (similar to camera apertures). An enlarger should spread light rays evenly over the negative. A Diffusion enlarger scatters the light evenly over the negative and produces about one grade less contrast than a condenser enlarger and minimises faults such as scratches and dust. The Condenser enlarger gathers the lamp’s rays and sends them straight through the negative. A Diffusion enlarger scatters unfocused light over the negative. Black and white contrast is lower and the effect of dust on the film and other defects is minimised. In this simple diffusion system, light from an incandescent bulb passes through a sheet of cloudy glass onto the negative. Diffusion or Colour head enlarger, for colour and B&W printing A Condenser uses one or more inserts to collect light and concentrate it directly on the negative. Exposures are shorter and black and white print contrast higher than a diffusion enlarger. Another type of diffusion enlarger bounces light from a high intensity tungsten - halogen bulb into a diffusion chamber above the negative. In this colour head three colour filters are built into the head for colour printing or variable contrast printing. Condenser enlarger, for B&W printing 38 Darkroom Tray Set Up The sequence for processing printing paper in the wet darkroom is, Developer, Stop Bath, Fixer, Rinse, Fixer 2, HCA then Wash. Test sheets may be viewed after the 1st rinse. Once prints have been washed thoroughly they can be put in the driers. All information (concerning exposure details and filters used) must be written in 2b pencil only. All wet paper must be carried in trays provided. Proof Sheet Exposure Assignment. To determine the correct exposure for making proof sheets. Testing exposure 1. Set the height of the enlarger so that the light will amply cover a sheet of 8" x 10" paper. 2. Open the lens to widest aperture. 3. Focus the edge of the light. 4. Set the lens aperture to f 5.6 (this is a starting point). 5. Set timer to 5 sec, depending on height. 6. Cut a piece of paper 5 cm wide, from the end of a 10 x 8 sheet. 7. Place a clear film strip onto the paper, emulsion to emulsion. 8. Cover with Proof sheet glass. 9. Cover four frames with card, leaving one half frame to be exposed. 10. Expose the paper by turning on the timer. 11. Move card one centimeter at a time until the whole strip is exposed. Mark the test strip of paper with felt pens or pencil where you are to place the card. 12. Write your details on the back of your test strip, such as name date, exposure, enlarger No. Filter. • The exposure immediately before that is the ‘minimum exposure time for maximum black’. • Re-test if too light, by increasing time, or if too dark by reducing the time. • Once this test is done and you have determined the correct time there is no need to do this test again unless you change your system in the following areas: time/ temperature or film/dev combination. Keep an accurate RECORD: (in note book or back of unexposed paper) Name Group No Enlarger No. F Stop Exposure Time in secs 13. Process the paper. Exposure Test For Proof Sheet After completing a routine step test, you will notice a range of tones progressing from light to dark. Identify a point on the contact print where you cannot distinguish a tonal change. Summary As paper is progressively exposed to light it will gradually change from light greyish to black (similar to film). At first a visible difference will be seen between the steps in exposure. As the time increases, the changes will become less noticeable to a point where a change in the density (black) will become indistinguishable Steps In Making A Contact / Proof Sheet (even though there has been a change in exposure). Follow the steps as outlined on the instruction sheets on test exposure to determine the time for proof sheeting. When the correct time is determined, make a proof sheet by exposing a whole sheet of paper. 1. Place the strips of negatives (approx. 5 frames) onto the paper with the shiny side up (six strips per 8 x 10 sheet), cover with proof sheet glass. 2. Expose paper by pressing timer switch, use the time selected in ‘minimum exposure for maximum’ exposure test on previous page. 3. Process paper. 4. Unexposed paper must be kept in the black light proof bags provided. Processing steps for RC paper 1. Developer time 1-2 min., agitate all chemicals 2. Stop Bath (water rinse)- time 30 sec. 3. 1st Fixer time 1 min., maximum 2 4. Rinse time 1 min 5. 2nd Fixer time 1 min 6. Hypo Clearing Agent time 2 min., maximum 7.

Set height of enlarger to suit required image size (full negative image). Focus image. Set aperture to f8. Cut a piece of paper for a test strip, 40 x 250mm, use your pen to mark lines across the paper at 30mm intervals. Place paper on easel shiny side up (emulsion up). Set timer to 3 sec. (depending on the degree of enlargement and negative density). Select an area of the image which has both highlights and shadow areas. Cover test strip with a piece of card, expose and move card, 30mm at a time, to have at least six exposures. Process, (see sheet on Making a proof sheet for steps). Choose the exposure time that gives a correct skin tone. Cut a piece of paper for a test exposure. (A second test strip) Place on easel and expose for new time, using the same method as you used for test strip. Process and check results (re-test if not right). Place full sheet of paper into easel. Expose and process paper.Multi - Grade Filters And Printing Paper ‘In printing we accept the negative as a starting point that determines much, but not all of the final image. Just as different photographers can interpret one subject in numerous ways, depending on personal vision, so might they each make varying prints from identical negatives.’ Ansell Adams 1983 Evaluating Density And Contrast In A Print. Prints are judged by density and contrast. This can be measured objectively and subjectively. The goal in printing is usually to make a full scale print one that contains a good range of tones (rich blacks, many shades of grey, brilliant whites etc.). Assignment:- Using Multi-grade Filters. Exposure governs the appearance of the Highlights Changing filters changes the appearance of the Shadows. Multi-grade filters are used with variable contrast papers. Variable contrast paper is coated with two emulsions, one which is sensitive to yellow/green light which yields low contrast and the second emulsion is sensitive to blue/violet light which produces high contrast. The filters affect ‘the colour’ of the light that reaches the printing paper from the enlarger light source and thus control contrast. The lower the filter No. the lower the contrast. The higher the Filter No. the higher the contrast. Filters come in half steps. You can change the contrast in different parts of a photograph by printing them with different filters.Multi-grade RC Printing Test Learning Outcome To give students first hand experience in using multi-grade filters and variable contrast RC papers. Method In consultation with a teacher select a negative of medium contrast which has a wide range of tones. Select the middle filter grade 21/2 and do a tone test to select the required time. Make a print on 5" x 3 1/2" multigrade paper. Now make a print at the same time using each of the whole number filters. That is, 00, 0, 1, 2, 3, 4, 5. Print Density Refers to the overall darkness or lightness of the print. It is controlled primarily by the amount of exposure given to the paper the greater the exposure, the greater the density of silver produced and the darker the print. Exposure can be adjusted either by opening or closing the enlarger lens aperture or by changing the exposure time. 41 Print Contrast Is the difference in brightness between light and dark areas within the print. The contrast in a print is controlled mainly by the contrast grade of the paper or, with the variable contrast paper and by the filter you select. A Low Contrast Print Sometimes called a flat print seems grey and weak, with no definite blacks or brilliant whites. A High Contrast Print Sometimes called a hard print seems harsh and too contrasty - large shadow areas seem too dark and may print as solid black. Highlights (very light areas) seem too light and may be completely ‘blown out’ (texture and detail are missing in shadows, high lights or both. Note: By the time you are ready to make a print, the contrast of the negative has been set, mostly by the contrast in the subject itself, the type of film, and the way it was developed.

How to make good prints quickly? I encounter several reoccurring mistakes with students learning to ‘print’. Especially with fibre based silver gelatin papers. After time management which I think affects us all, maximising information garnished from a test strip is one of the next issues that can be addressed by any student quickly and easily. [Even I need to learn better time management skills!]There are others. They are:Making time count in the darkroom? How to learn as much as possible as quickly as possible, i.e. learn from our mistakes? How to learn when to go back and try again, but differently this time? Making time count. The best way to make time count is to get the most out of each test strip.So how does one get the most information from a test strip, in the immortal words of real estate agents the world over. ‘Position position position’! Careful placement of the initial test strip will allow you to make quick decisions based on the feedback you receive from the test strip, if that placement is optimised to give that feedback. So put the test strip in a position where you can give a trial exposure to BOTH the shadows and the highlights in a single test strip. These two main areas the HIGHLIGHTS and SHADOWS, govern decisions on exposure time and contrast or filter choice. If the test strip has both highlights and shadows then the choice made for the best exposure time can be checked against the corresponding shadow value, and if needed a change can be implemented at this stage saving one whole test strip. Of course the actual placement will vary from print to print, so long as the test strip includes the necessary tones the printer can save lots of time. Learning from our Mistakes. This may seem really simple but it takes a students a while to realise this, but the simple act of bringing the last test strip out with you each time you need to look at your work will help immensely It will have a two fold effect. You will learn more about printing quicker You will learn if you are making the right kind of decisions quickly. A. In the days before Photoshop extreme patience was needed here, now it’s not so tough. The quantity of imperfections though may even make Photoshop™ a no goer here. In the end you need to evaluate the quality of the shot and it’s suitability in your folio/job. Does it justify 4 days in the darkroom? Maybe you can justify continuing with it then if it is that ONE shot! Is it impossible for me to go back and re-shoot? Then - sigh - you’ll just have to keep slugging away at it. So bring each test strip or work print out of the darkroom every time you need to examine your results and before you know it you’ll be a ‘gun printer’ in no time. Writing on the back of your test strip as well helps immensely, use pencil though! Enough is Enough Sometimes it is better to face up to reality and just re-shoot or try another negative. If you have made your proof sheet to edge black, then maybe you wont even need to go in the darkroom, but sometimes this ‘judgment’ gets the better of us and we ‘think our negs are ok’. If you have been in the darkroom for many hours and have nothing concrete to show for it then perhaps it’s time to re-shoot.Learning when a neg is beyond printing is the hardest lesson to learn of all. Here’s some questions/answers to help you make that choice. Q. Have I tried both different aperture exposure combinations to get a good white and black? None of them come close less time makes the white too grey, a higher filter makes the print too harsh or not harsh enough? A. The neg is probably so badly exposed and developed that no end of work can fix it, time to re-shoot. Q. I am up to huge time say over 150% more time for burning in on this print? A. This neg is so over developed that no end of work will fix it time to reconsider it’s worth or re-shoot Q. Looks like some one tried to skate on this neg or did I really take that shot in snow storm? 43 Advanced Options for B&W Silver Gelatin Printing. Split Filter Printing, Making fine prints with todays Materials One of the most ignored aspects to Multi contrast papers is the ability to use more than one filter to make a print. As the main paper manufacturers are now cutting back or reducing the varieties of fibre based papers that they offer,a good understanding of how to exploit the current crop of Multi Contrast papers is essential. As a resource for further research I highly recommend Steve Anchell’s book, ’The Variable Contrast Printing Manual’pub Focal Press 1997. Multi contrast papers are are relatively recent innovation in the world of Black and White photography. It was first thought to have been introduced to the world around 1940 - the idea had existed for a lot longer since 1912 but the then current crop of emulsions could not support it - Frank F. Renwick a scientist at Ilford.1 Multi-grade papers didn’t really catch on when they were commercially introduced, they were considered ‘inferior’ to the more established graded fibre based papers. As someone who has only used modern fibre based papers I can’t offer an opinion here. My favourite papers; when they were available; had characteristics that I exploited with my film exposure and processing. I felt these graded papers were superior especially given my overall approach to printing papers and developers. However during my recent Masters project I discovered to my horror that Agfa has stopped making my favourite paper, ‘Portriga Rapid’. This means that I’m now going to have to think about using Multi contrast papers. The best way to ‘exploit’ the papers then is to use more than one filter to print them. There are several ways to do this, all have one thing in common though. The filters need to be in a position where they are easily accessible. This is usually under the lens - a word of warning keep the filter as close as possible to the lens to avoid possible image degradation caused by dust and scratches on it this then means at any point the filter can be changed with out disturbing the negative in the enlarger. The most simple and direct way to use more than one filter in printing is to use a higher or lower number to burn in areas locally in the print. For example, you can lower the contrast of the sky in an image by ‘burning in’ using a lower numbered filter than the one used to make the print. Or conversely you can burn in the shadow areas with a higher contrast filter to make the shadows more contrasty. A more complex approach is to combine both the highest filter and the lowest filter, to add more versatility to the whole process. Say you liked the 30 second exposure time for the ‘00’ filter this means that when you return to the darkroom and do your next test strip it will have an exposure time of 25 seconds on filter‘5’ and 30 seconds on filter ‘00’. If you are pleased with the results, proceed, however, and this where the advantages of this paper real kick in, try another exposure time at say 20 seconds on filter ‘5’ and 35 on filter ‘00’. This will give a different contrast to simply lowering the filter from 2.5 to 1.5 for example. Split filter printing will not create any contrast that the paper cannot. What it will allow is precise control over the values in the print. Here’s how it works. First place your highest number filter in your filter draw, say a number ‘5’filter. Place your paper in the easel and do a series of test times across the paper. Next change the filter, leaving the paper in the easel. Put in the lowest filter in the pack. Ilford make a ‘00’. Now do another test strip this time expose the paper at 90 degrees to the first test. Process as normal and examine the print. You should be presented with a print that has a dark and overly contrasty appearance on one corner, and the opposite on the adjacent corner. Counting across the paper in one direction, pick the time that best suits your intention. From that time count the other exposure time for the other filter. This combination of times will be your next test strip. What this means is this, say you counted across five exposure times on the test strip in the 5 filter direction, and they were 5 seconds each. This gives you an exposure time of 25 seconds with filter 5. 44 Fibre Based Paper Developers. Assignment. Objective. Evaluate the characteristics associated with a variety of printing materials. Use the following developers 1. Agfa Multi contrast Developer. 2. Agfa Neutol Developer. Print a well exposed negative in a variety of paper developers . Take a well Exposed Negative, print on 2 different papers. Get the paper from the store. Use the developers listed above. When you make your prints, match each print’s highlights carefully. Expose the paper as much as each developer and paper type needs and do not change filters. Develop each print for three minutes. Make notes on the back of the print as to the type of paper,type of developer and all enlarger settings, including exposure time, aperture and filter used before putting the paper in the developer. [Do this before you immerse the paper in the devlopers] File all results in your technical journal, and write up your conclusions. Points to look for are print colour, [is it warm or cool in appearance], contrast [local /global] differences in exposure time and rate of development. 45 Toning Silver Gelatin Prints. Toning silver Gealtin prints serves a two fold function. 1. To make the print more archival 2. To change or modify aesthetic values in a print. Here's a definition from http:// photography.about.com. Toning means any procedure used to change the colour of the black and white photographic image. It differs from dyeing, which is used to colour the base material on which the image is coated. Toning is used for two purposes, first and most obviously for aesthetic effect in changing the colour, but also some toners make the image more stable. Toners used for archival purposes include gold, selenium and sulphide toning. Gold toning is seldom used, largely because of its cost, but also the cold blue-black tones produced are seldom desirable. Selenium toning is widely used for archival purposes and also for the slight cooling of the image and the more intense blacks it produces. By far the most effective archivally is however sulphide toning, but it also gives a sepia colour. presence of various environmental pollutants. You should always take normal precautions - such as wearing safety glasses and avoiding skin contact by wearing gloves or otherwise - when handling chemicals, and store them in sealed labelled bottles out of the reach of children. Always read the MSDS safety information on all chemicals you use. Fixing: of Toned Prints Adequate fixing is necessary to remove unexposed silver halides, which, if left in place, would react with light and degrade the image. Most practitioners today use Ilford’s processing method for prints, which specifies rapid fix (with ammonium thiosulfate instead of sodium thiosulfate) at “film” strength, i.e., diluted 1:3 or 1:4 instead of the old “paper” dilution of 1:7, for about one minute (compared to the 5 to 10 minutes required in a sodium thiosulfate fix). The concentrated ammonium thiosulfate provides adequate removal of unexposed silver halides while reduced time in the solution prevents fix from penetrating into the paper base where it is very difficult to remove. Photographers would do well to remember that over-fixing of prints is equally detrimental to archival quality, in the long term, as under- Silver halides are the most sensitive materials available for use in photographic emulsions, but unfortunately metallic silver oxidizes very readily, so that silver images formed in our prints require protection or stabilization in some way. Archival processing involves fixing paper adequately to remove unexposed silver halides, washing appropriately to remove excess fixer, and preferably treatment with some sort of toning or sequestering solution to prevent the emulsion silver from oxidising in the fixing. My personal method for prints is to utilize two trays of rapid fix, agitating the print in each tray for 30 to 45 seconds. When the second tray of fix has reached half its recommended capacity, it moves to the first tray and I prepare a second tray of fresh fixer. The two-tray method increases the useful life of the fix by reducing contamination in the second fix, assuring adequate fixation. Kodak’s “Residual Silver Test Solution ST-1” may be used to determine if paper or film is properly fixed. I should note that the traditional method of fixing prints in a sodium thiosulfate solution for 5 to 10 minutes is perfectly acceptable, so long as fixing and washing times are adequate. Washing of Toned Prints Adequate washing is necessary to remove residual thiosulfates (fix) in the print, which could otherwise cause the print to deteriorate over time. With the use of a wash aid such as Kodak Hypo Clearing Agent, Orbit Bath, or Perma-wash, the time required for washing prints can be reduced to a half-hour or less, assuming that Ilford’s method of rapid fixing has been followed. Toning Affects. Sepia Toner Sepia in highly dilute forms can be used to tone only the highlights, it is a two part toner which if each part of the process is modified in terms of timing different results can be achieved. Sepia is a warm toned toner and will warm the print colour up. Selenium Toner. Selenium mainly affects the shadow areas of a print. It intensifies the blacks and cools the overall print colour down. Given this information it is possible to achieve an effect whereby the highlights are warm and the shadows cool in colour thereby achieving a rather interesting look. This look can affect the spatiality of the prints as warm colours come forward and cool colours recede. Both toners, will stabilise a print and make it more archival, and able to endure the ravishes of time. Tea Assignment Print Toning Time and Dilution Most toning is done by inspection this means, that the actual time that you leave the print in the toner will depend on the degree of the effect you require. Dilution also affects the results, the stronger the dilution the quicker you will see the depth and intensity of the print colour. We recommend lower levels of dilution thereby allowing easier control over the final results. Sepia & Selenium combined. Use the Sepia first!!! Sepia Soak in water first, then part “A” bleach 1 +32, 30 seconds. Rinse in the middle tray of water Part “B” toner 1+16, 1 minute. Give the print a very thorough rinse!! Selenium 1 + 3, 2 minutes. HCA the print for 3 minutes Set up the appropriate trays in a well ventilated area, get out all the tongs. Set up trays for the toners and a separate tray for HCA for each toner. One large tray of water is required to soak all the prints before starting. As a starting point for you we will give you a list of suggested starting times. Write these on the back of your prints Before you start toning. You have a spare print/s to use as an experiment. As always all solutions are at 20˚ Celsius. Sepia toner, steps. Set up three trays one with water in it, one with the bleach in it, and one with the toner in it. Soak in water first, then part “A” bleach 1 +32, 30 seconds. Rinse in the middle tray of water, then, part “B” toner 1+16, 1 minute. Finally HCA the print for 3 minutes Soak in water first, then Part “A” bleach 1 +32, 60 seconds. Rinse in the middle tray of water, then, part “B” toner 1+16, 4 minutes. Finally HCA the print for 3 minutes As long as you desire, at least 4 minutes though. Use the last print to experiment One print is to remain un-toned to allow you to compare the effects of the toners on your prints, some affects are subtle and this will enable you to “see” the results. Washing and drying. At tthe end of the toning session add the prints to the archival washer for a 60 minute wash, then hang in the processing room to dry.

Digital images can also be focused by the lens, as opposed to an used chemical photographic made by scanning conventional exposure on light sensitive film. The processing to develop and stabilise photographic images. captured image is then stored as a the image. By contrast, digital digital file ready for digital processing photographs can be displayed, (colour correction, sizing, cropping, printed, stored, manipulated, etc.), viewing or printing. transmitted, and archived using digital and computer techniques, without chemical processing. Digital photography is one of several forms of digital imaging. Digital images are also created by non-photographic Introduction to Digital Photography There are two main ways of making computer images: either raster or vector. Raster images or [bitmapped] are made up in a grid fashion of pixels. Paint programs use bitmapped images. Resolution is an important consideration when working with raster images because if it is too low, ie. 72 ppi when scanned or created, edges may appear jagged. The squares [pixels] that make up the image become bigger because there are less of them Vector images are made up of mathematically defined lines or curves. that refer to a specific shape drawn at a specific location on the page. The shapes may be moved enlarged or reduced without changes to the rest of the image or changing the clarity or sharpness of the lines. Resolution An important factor in bitmapped files is resolution. There are several types: image resolution, bit resolution, monitor resolution, screen ruling, and output resolution. Image Resolution This refers to the amount of pixels in an image when created or scanned., and is measured in pixels per inch. The image resolution you set determines the resolution of the image when it is exported into a desktop publishing program and the maximum resolution at which you can print the image. You need to be aware of how you are going to transport the image around and what kind of printing facilities you will use. The more pixels per inch in an image the greater the amount of data, which increases your file size. Bigger file sizes require more RAM, take longer to do manipulations and longer to print out, yet have greater detail. An image with a resolution of 72 ppi is 72 pixels x 72 pixels = 5184 pixels [1square inch] A 3 inch square image at 72 ppi is 216 pixels x 216 pixels = 46,656 ppixels A 3 inch square image at 360 ppi is 900 x 900 = 810,000 pixels. Bit Resolution This refers to BITS per PIXEL or how much colour information is available for each pixel. Also referred to as pixel depth or bit depth. Greater bit depth means more available colours and more accurate colour representation in the image. A pixel with a bit depth of 1 has 2 possible values, on or off. A pixel with a bit depth of 8 has 28, or 256 possible values. A pixel with a bit depth of 24 has 224, or 16 million possible values. Monitor Resolution This determines the size an image will be displayed. An image with 114 ppi is displayed at twice its actual size on a 72 dpi [dots per inch] monitor, because only 72 of the 144 pixels can be displayed per inch. Output Resolution This refers to the number of dots per inch [dpi] that the output device or printer is capable of. Laser printers usually have an output resolution of 300 to 600 dpi. High end imagesetters can print at 1200 dpi, 2400 dpi or higher. Generally though output devices are measured in lines per inch, including printers and film recorders. Image Size This refers to height, width and ppi. If you change any of these independently the file size will change. In Photoshop there is an option for changing the image size. The dialogue box for image size gives you information on an ability to change File size, Pixel dimensions (in height and width), Print size Height and Width (in pixels, cm, inches) Resolution (in ppi or ppcm) Height and width can be locked in together by checking the constrain proportions box, then, if height changes automatically width changes. Resolution can also be locked into height and width, by un-checking the resample image box. Un-checking resample image means the existing pixels are used to make up the image size if the height or width is changed. For example If the original image has a File size of 2.32 mb 900 pixels by 900 pixels Height 3 in, Width 3 inches Resolution of 300 ppi If you change the height to 4 in Width becomes 4 in Image is still 900 pixels by 900 pixels Resolution becomes 225 ppi File size remains 2.32 mb To change height or width without changing the resolution, the resample image box must be checked. Now if you make the height or width bigger Photoshop will check the range of the image for similar pixels to add. With this option, if you change the height to 4 inches Width changes to 4 in Resolution remains 300 ppi File size changes to 4.12 mb Pixel dimensions 1200 pixel by 1200 pixel This is however a less than satisfactory way of changing image size in Photoshop™. This method works well if you are making the image smaller but does not produce satisfactory results if the image is needed to be bigger. This is because Photoshop™ examines each pixel and “guesses” the value that the new pixel should be producing less than photo realistic images. The lesson here is that scan in your image at the appropriate size for your desired result. 50 Digital Photography Characteristics Some general characteristics of an analogue photograph:• mechanically produced origins • potential for mass reproduction • links with commerce • apparent lack of the need for ‘artistic’ skill. • in transition: always easily open to manipulation • in transit: transmittable, mobile, and viewed on screens • in a transient state: ephemeral, inherently erasable and can be destroyed with little physical effort Digital photographs offer a different experience to their analogue counterparts. Photography as a medium has gone through a process of ‘dematerialisation’. Digital files are virtual, rather than physical objects. As Batchen was arguing by 2001: [T]he substance of a [digital] image, the matter of its identity, no longer has to do with paper or particles of silver or pictorial appearance or place of origin; instead it comprises a pliable sequence of digital codes and electrical impulses . . . It is their reproduction, consumption, flow and exchange, maintenance and disruption, that already constitute our culture. (Batchen 2001: 155) Such photographic images are now as likely to be viewed on screens – via computer monitors, mobile phones, digital photo frames, shop displays, street advertising, plasmas – as they are in print. We live in what Manovich calls ‘the society of the screen’ (Manovich 2001: 94). This can be seen as changing the viewer or viewers’ relationship to the image, effectively disembodying the observer. Manovich contends that images on screens move, while viewers remain immobile (2001: 94–115; see also Chapter 3). Physical relationships with photographs alter as a result. For example, to look closely at a material photograph on paper, Joanna Sassoon notes, involves moving the photograph or moving the body nearer to it. A digital photographic image on a computer screen can be zoomed in taken than ever before. These images are captured with the instantaneity that has been part of photography for and out of via the mouse or keyboard with almost no movement by the viewer (Sassoon 2004: 192). Nevertheless, it can be countered that viewing digital photographs on hand- most of its existence – but there are also more photographs being instantly deleted than ever before too (see Rubinstein and Sluis 2008: 13). The erasing of a digital file can happen as held devices (mobile phones, iPods, portable digital photo frames in the form of key rings, etc.) often returns the image to a social object to be passed around and discussed quickly as its creation: it is much faster, more final and far less physically demanding than the material destruction of a fixed negative or printed photograph. (Manovich 2001: 114). Furthermore it is important to note that the simulation of physically connecting with pictures via the ‘touch screens’ of some digital devices (such as iPhones) now closely Mitchell has contended that digital files require no negative or print to exist and can, in principle, be endlessly replicated (Mitchell 1992: 6), although Manovich has pointed out simulates the materiality of physical photographs (Edwards 2009: 31–33). Photographs in digital form are more mobile than ever, being transmitted around the world (often within that duplication often leads to a loss of digital information via compression (for example by turning a file into a JPEG) (Manovich 2001: 54). Transmission online also means that seconds of being taken) from email to email, website to website, uploaded and downloaded. With smaller memory size images are used, resulting in images with an absence of fine detail (see Chapter 6). Digital cameras, memory cards and memory sticks can, of course, also be lost. © Bull, Stephen, Dec 15, 2009, Photography Routledge, Hoboken, ISBN: 9780203867297digital technology, electronic mass reproduction of photographs goes way beyond Benjamin’s idea of mechanical mass reproduction (Benjamin 1999). In this sense the digitally reproduced image shares some charac- teristics with the postmodernist thinker Jean Baudrillard’s idea of the simulacrum. Extending Benjamin’s ideas relating to the era of modernity, in the 1980s Baudrillard argued that we increasingly live in a virtual world of copies – simulacra – for which the real original has been lost. The simulacrum is a copy of a copy of a copy . . . ad infinitum (Baudrillard 1984: 253–281). Like the simulacrum, the digital photograph has no definitive original version, yet is capable of going anywhere. Digital photographs are simultaneously everywhere and nowhere. With digital cameras and camera phones more photographs are being However, the ability to endlessly backup digital images combined with the ease in which erasure can occur, mean it could be argued that the loss of a digital file no longer involves the potential trauma that Barthes identified with the physical destruction of the printed photograph, or of the unique negative Kodak’s First Digital Camera 1975 In December of 1975, after a year of piecing together a bunch of new technology in a back lab at the audiences throughout 1976. In what has got to be one of the most insensitive choices of demonstration playback system. I especially remember working with Jim for many hours in the lab bringing this concept Elmgrove Plant in Rochester, we were ready to try it. “It” being a rather oddlooking collection of digital circuits that we desperately tried to convince ourselves was a portable camera. It titles ever, we called it “Film-less Photography”. Talk about warming up your audience! After taking a few pictures of the to life. Finally, I remember my visionary supervisor, the late Gareth Lloyd, who supported this concept and helped enormously in its presentation to our internal world at had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable attendees at the meeting and displaying them on the TV set in the room, the questions started coming. Why would anyone ever want to view his or her pictures on a TV? How Kodak. In thinking back on it, one could not have had a better environment in which to “be crazy.” Many developments have happened between this early work and today. contraption, we shoehorned in a portable digital cassette instrumentation recorder. Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD would you store these images? What does an electronic photo album look like? When would this type of approach be available to the consumer? Although we attempted to Personal computers, the Internet, wide bandwidth connections and personal desktop photographic printing are just a few of these. It is funny now to look back on this project and realise that imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a address the last question by applying Moore’s law to our architecture (15 to 20 years to reach the consumer), we had no idea how to answer these or the many other challenges that were we were not really thinking of this as the world’s first digital camera. We were looking at it as a distant possibility. Maybe a line from the dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like. suggested by this approach. An internal report was written and a patent was granted on this concept in 1978 (US 4,131,919). I kept the prototype camera with me as I moved It was a camera that didn’t use any film to capture still images - a camera that would capture images using a CCD imager and digitise the captured throughout the company over the last 30 years, mostly as a personal reminder of this most fun project. Outside of the patent, there was no public disclosure of our work until scene and store the digital info on a standard cassette. It took 23 seconds to record the digitised image to the cassette. The image was viewed by removing the cassette from the camera and placing it in a custom playback device. This playback device incorporated a cassette reader and a specially built frame store. This custom frame store received the data from the tape, interpolated the 100 captured lines to 400 lines, and generated a standard NTSC video signal, which was then sent to a television set. There you have it. No film required to capture and no printing required to view your snapshots. That’s what we demonstrated to many internal Kodak technical report written at the time sums it up best. “The camera described in this report represents a first attempt demonstrating a photographic system which may, with improvements in technology, substantially impact the way pictures will be taken in the future.” 2001. The “we” in this narrative was largely the people of the Kodak Apparatus Division Research Laboratory in the mid 1970’s and, in particular, several enormously talented technicians - Rick Osiecki, Bob DeYager and Jim Schueckler. All were key to building the camera and 52 History of digital photography The beginning: You may be surprised to learn that the origins of digital photography lie as far back as the 1950s. Yes, it’s the time of the baby boomers, the cold war and the space race! These are events that do actually have significance in the history of digital photography. I’ll come to those later, but the first significant development in comes from another boom of the era – television! In 1952 the first video tape recorders were used to record TV programs. Before this, most television was either live, or was a broadcast movie. With video tape an image was recorded, not as an image in itself, but as a coded signal on tape. Later the coded tape was run through a decoding machine (i.e. a video tape player) and the machine converted the coded signal back into pictures. This is an important step in the history of digital photography. Video differed from the films that had gone before because film records an actual image, frame by frame. Pull out an old cinema reel and you’ll see the frames. Pull out cassette tape and you’ll see nothing! It needs to be decoded for you first. The effect is the same as comparing film vs digital photography. Look at a developed film (the negative or slide) and you will see an image. Pull a memory card out of a digital camera and there’s nothing to see. The image held on the card needs to be decoded first. The scanner appears History of digital photography – the scanner: Back to the history of digital photography rather than the history of the moving image. The next significant step would be the development of image scanners. These didn’t actually take photographs, but they did copy an image already created. In 1957 a “drum scanner” was developed by Russell Kirsch. The scanner picked up the different intensities of light and shade in a picture. It saved them as a binary, i.e. digital, signal. NB: Photocopiers stem from the development of this technology. The first one was made by Xerox in 1959. A huge thing, slow and expensive. But remarkably popular nonetheless. Up, up and away! History of digital photography – the space race! As I mentioned above, the space race has a big part to play in the history of digital photography. It’s 1957. Von Braun is in the American corner, and Sergei Korolev in the Russian corner. Both are trying to launch a satellite into space. The Russians win that round with the launch of "Sputnik" in October 1957. The race was really on! The next challenge was to launch a man into space. We’re bring the film back to Earth somehow. And if it didn’t make it back to Earth – no pictures at all! So a new system was invented that didn’t need film. Digital cameras were the answer. They could record photographs and ‘beam’ the digital signal back to Earth. The signal was then decoded and the image could be viewed. This then is clearly a big development in the history of digital photography. History of digital photography – digital cameras come to Earth! Following the exploits of digital cameras in space, the concept of photography without film came back to Earth in 1973. An engineer, Steven Sasson, working for Kodak used a CCD to produce a digital image. This camera weighed in at a hefty 8 pounds. And it only had 0.1 megapixels - not really designed for the consumer then! To be fair, it was experimental rather than commercial. Importantly though it truly was a digital camera in the way we are familiar, because it recorded images onto a solid chip (CCD) rather than onto tape. Clearly more development was needed. At this point people were beginning to realise that digital cameras may have a use back here on Earth. Nobody expected film to be replaced by digital cameras at this stage though. The first consumer digital cameras are still some way off. moving into the 1960’s now. Why was the space race important to the history of digital photography? Well, very early on politicians on both sides of the cold war realized that if a satellite could be launched into space it could carry a camera. With a camera on board it could spy on the enemy. The problem of course was this – there are no film developers in space! Taking pictures on film meant you had 53 The first consumer digital cameras: Following the exploits of digital cameras in space, the history of digital photography moves back to Earth here. This page covers the history of consumer digital cameras – the ones we are all familiar with. A new era in photography began on August 25, 1981 when Sony unveiled a prototype of the company's first still video camera, the Mavica (Magnetic Video Camera). It recorded analog images on two-inch floppy disks (memory sticks hadn’t been invented back then!) and played them back on a TV set or Video monitor. NB: The ‘Mavica’ name comes from Magnetic video camera. The Mavica was not a digital camera, but a still analog version of the video cameras of the time. The difference between still video images and digital images is a bit like the difference between analog vinyl LP records and today’s digital music. The analog version is a physical representation of music; while the digital version is an encoding of the music. Various companies produced still video cameras throughout the ‘80s. In 1988 Fuji marketed the first consumer all –digital camera, the DS-1P. In 1990 Dycam marketed the first consumer digital camera sold in the United States, the Dycam Model 1 (also sold by Logitech as the Fotoman). Storing images on floppy disks was an important development because it meant that, the number of photographs that could be stored was, effectively, limitless. If you filled the floppy disk up with photographs you just inserted a new blank disc. The capacity of these blank disks was less than 1MB. Back in 1981, and with a Mavica, you could store about 25 photographs on one disk. NB: A high quality photograph from today's digital cameras is easily 1mb. At best you'd only be able to store one photograph on a floppy disk! Thankfully, the memory card has been invented since then, capable of storing hundreds of digital photos. From this point forward the history of digital photography is one of improvement rather than new development, with the possible exception of the Foveon X3 image sensor. The race for more megapixels History of digital photography – sensor improvements: The improvements of digital imaging sensors is an important part of the history of digital photography. In 1981 Sony’s Mavica, with 0.3 megapixels, was never going to be enough for good quality digital photography. Viewing photographs on screen was possible, but prints were lousy! To get good quality photographic prints the resolution had to be improved. To get a good quality snapshot print you need to have at least 2 megapixels, and ideally 3MP. So, although Sony were first through the door of the digital photography party, their first digital camera was limited in both its use and popularity. For consumers, the history of digital photography springs to life with the introduction of 2 and 3 megapixel cameras. Nikon were first past the post on this one, introducing two 2 megapixel cameras at the start of 1999. One camera had a zoom lens (the “Coolpix 950”, shown here), the other (“Coolpix 700”) had a fixed focal length. History of digital photography – The Foveon sensor: In 2002 Foveon started producing a new image sensor. The reason why this is an advance is that up until this point digital camera sensors have recorded only one type of light at a given location. Individual ‘photosites’ (these are the pixels of the sensor) collect information about either red or green or blue light. The difference with the Foveon sensor is that it collects information about Red, green and blue light at every photosite. The image below illustrates the difference: A Rebel with is born NB: Kodak had already introduced “professional” digital cameras with 6 megapixels before 1999, but their camera could hardly be considered one for the consumer – it weighed 3.75 pounds and had all the style of a house-brick! It's not just about the size of your megapixels, it's what you do with them! 54 History of digital photography – consumer SLRs: The development of digital cameras continues from this point with the cameras steadily improving all the time. They now have even more megapixels and cost even less. The next significant step in the history of digital photography is the introduction of the digital SLR. Digital SLRs had been available up until now, but they were strictly for the professionals. Costly and heavy they were never going to become mainstream. Canon changed all that in August of 2003. In the summer of 2003 Britain was recording its hottest day ever (101.3 degrees at Faversham in Kent) and the lights went out on 50 million North Americans – the result of a massive power outage. Canon was launching the Digital Rebel. This camera is of huge significance in the history of digital photography because it was the first affordable digital SLR. Suddenly keen amateurs with film SLRs, who had built up a lens collection, could just take their lenses from their old film cameras and attach them to the new Canon. The camera also offered fast response times unlike the compact cameras up until this point. For film, the end is nigh What of the future history of digital photography . . . The improvements in film photography led to smaller and better cameras; the improvements made throughout the history of digital photography have led to more pixels, smaller cameras, lower costs and greater memory capacity. Today it’s possible to buy a reasonable 8 megapixel camera for under $300. Technology never stands still though. Few would have predicted the stunning growth of digital photography, even ten years ago. And now digital cameras outsell film. Some manufacturers have already pulled out of the film market completely. So, with film cameras going the way of the dodo, perhaps the history of digital photography truly starts now? Sub 3 megapixel cameras are now very hard to come by. The starting image resolution for a "bottom of the range" digital camera is now around the 6 megapixel mark. An interesting development is now the growth of digital cameras aimed specifically at children. Last year (2007) Fisher Price and Vtech have both recently launched digital cameras aimed specifically at children. These models are robust, and cheaper than the "adult" versions. As I said earlier, the history of digital photography continues to evolve. The Lytro camera is in 2011 the camera of the future 55 Film compared to Digital As a starting point it is worth remembering how a photograph is taken in the first place. In simple terms, light focused through a lens hits some sort of light sensitive material. In the case of film the material it hits is the film itself. For digital The light sensitive particles of an image sensor are called photo-sites. These record the intensity of light at a certain point. There are millions of these photo-sites on a sensor. They are effectively the pixels in “megapixels”. In film the light sensitive particles are colour sensitive emulsions. These contain fine particles. The particles are seen in the final image as film “grain”. Film vs Digital - Practical differences: The table below illustrates some of the practical differences of film vs digital cameras. Negative points are in green, positive in red, neutral in purple Film: Digital: Image captured and stored on the film itself. Image captured on the image sensor and recorded onto a memory card. Once film is exposed to light it cannot be used again – more film has to be bought. Once a memory card is full of images, they can be downloaded onto a computer. The memory card can then be wiped and used again. To view photographs the film has to be developed using special chemicals. Photographs can be viewed instantly, either on the digital camera or on a computer. Editing photographs can very difficult to master and requires a darkroom. Editing of photographs is faster and can be done on a home computer. Batteries last a long time in a film camera. Digital cameras eat batteries at a fair rate of knots! Film cameras are usually very responsive quick to start up, quick to focus and no delay on releasing the shutter. Compact digital cameras take a couple of seconds to start up, can be slower to focus and some have a fraction of a second shutter delay. [NB: Digital SLRs suffer far less than compacts] It’s worth having a look at these practical differences because the issue of film vs digital is not only about picture quality. There's more to film vs digital than just the quality If a digital camera is slow to start and focus you may well miss photos that a film camera would have captured. The quality of digital cameras may impress. But that’s of little consequence if the subject you were photographing has moved on before the camera was ready to take the picture! How does the quality of film vs digital vary? Film vs Digital – differences in quality: It used to be the case, not that long ago, that digital cameras never matched the quality of film cameras. Slowly the gap narrowed. Good (and very expensive!) digital cameras began to take better quality photos than cheaper film cameras. Then the more affordable digital cameras improved. To get better quality with film you had to start spending more money on better line is near, and digital is edging ahead all the time. Film vs digital and the tonal range For a balanced film vs digital discussion we have to realise that there is more to quality than just producing a sharp picture. The tonal range also matters. In simple terms, tonal range is the number of grades of light to dark in a photograph. Digital photography is generally limited to 256 grades. Film is effectively an analogue medium so theoretically can produce limitless grades of light to dark. In the issue of tonal range, film seems to win the film vs digital debate. How does this limited tonal range affect digital photography? With a digital camera, bright areas of an image can record as pure white. Even though there are actually some shades within that area. These parts of an image are said to be burnt out or blown highlights. equipment. The film vs digital pendulum was swinging in favour of digital. The same applies to dark, but not quite black areas of pictures. Digital cameras will record the whole area as pure black. This is less of a problem as the human eye doesn’t notice these These days the quality of digital dark areas so much. Digital camera quality is often measured in megapixels. More megapixels means every individual pixel (or dot) in the final picture will be smaller. The smaller they are, the sharper the picture will be Be careful though! The number of megapixels alone doesn’t always make a good camera. For film, the equivalent "pixels" are actually film "grains". The size of the grains depends on the speed of the film used – faster film (more sensitive to light), has larger grains. These grains will be visible in the final print. Concerning film vs digital, a good quality 4 megapixel digital camera equals fast film, pixel for grain. Most people would use slower film though, so this is what we should compare for a balanced film vs digital comparison. For standard film it is generally considered that a good 8 megapixel digital camera is about equal, pixel for grain. cameras outstrips all but the most specialised film cameras. And by specialised I mean large and medium format cameras. I took the photograph below at the Chinese New Year Celebrations in London (great day out by the way!). The evidence for this lies in the sale of cameras. Kodak has already pulled The clouds in the photograph clearly show the differences in tonal range from film vs digital. out of the film market. Even Nikon’s professional film cameras are going, with the sole exception of the Nikon F6 – their highest spec film camera. The first image shows what film can produce. The second shows the blown highlights that can sometimes result from digital photography. Professional photographers demand high quality. If the professionals are leaving film cameras behind then it’s safe to assume that digital cameras have come of age. If anyone thinks digital hasn't won the film vs digital competition, they must at least acknowledge that the finish Film vs digital - what about the "grain"? Film vs Digital – "grain" vs "megapixels": Finally, you may be interested to find out how “megapixels” fit into the film vs digital debate. 57 Film vs digital - conclusion Well, that's a tough one. No matter what people say, when it comes to film vs digital there will be fans on photographers will ever notice the difference. both sides of the fence. One of the easiest ways to think about the film vs digital issue is to relate it to vinyl records and CDs. CDs are convenient - easy to find a track, play well, no scratches or rumble. With CDs people have access to good quality music that's in a format that's easy to use. Butvinyl records are still on sale. Hardened music fans insist that the quality of vinyl can never be matched by the quality of a CD. And in theory they are right. An analogue record has all the tones, the digital CD only has some. Can the average person tell the difference? Nope! They prefer the convenience of CDs, and well, they sound just fine, don't they? The same can be said of film vs digital. Film is analogue. It has all the tones. But digital is easier to use, and can most people tell the difference? Nope! As a final conclusion about film vs digital then - film will always have its fans, but digital will be the most popular. And as for quality - only the really, really pickiest of 58 Colour and computers The properties of colour can be mathematically defined using one of several colour models. Four of the most common models are1. hue, saturation and brightness [HSB]; 2. red, green and blue [RGB]; 3. cyan, magenta, yellow, and black [CMYK]; 4. CIE L*a*b* 1. HSB HSB is based on human perception of colour. Hue is the wavelength of light reflected from an object. Saturation is the strength and purity of the colour. Brightness is relative to the darkness or lightness of the colour, and is usually measured as a percentage from 0% [black] to 100% [white]. 2. RGB RGB model is based on the three primary colours red, green, and blue. When the three primary colours overlap they create secondary colours, cyan, yellow and magenta. Adding all the colours together creates white, thus they are called additive colours. Additive colours are used for lighting, film, video, film recorders and monitors. A monitor creates colours by emitting light through red green and blue phosphors. 3. CMYK CMYK model is based on the absorbing quality of ink printed on paper. In theory, pure cyan, magenta and yellow pigments should combine to absorb all colour producing black, for this reason they are called subtractive colours. Because printing inks contain some impurities they actually make a muddy brown, a black ink must be added to get a true black. The letter K is used for black so there is no confusion with calling it blue. 4. L*a*b* L*a*b* colour is designed to be device independent. It creates consistent colour regardless of the specific devices, such as monitor, printer, or computer, that you use to create or output the image. Lab colour consists of a luminance, or lightness component [L], and two chromatic components: the a component, which ranges from green to red, and the b component which ranges from blue to yellow. 59 File Formats in digital Photography. File formats are the way data is saved to a disk. Particular file formats are required for specific uses. RAW Most professional level DSLRs and some high end point and shoot cameras allow images to be captured in a raw unprocessed format. Each camera maker and sometimes even each camera model may have a different proprietary format. Convert your files to DNG the universal format to archive and make them future proof. Shooting in RAW has advantages over JPEG most of the time. So unless you are pressed for time or disk space it is better to shoot in RAW and use a computer to convert them to a useable format, after the shoot. PSD Photoshop format is the default file format and the only format that supports most Photoshop features besides the Large Document Format (PSB). Due to the tight integration between Adobe products, other Adobe applications like Adobe Illustrator, Adobe InDesign, Adobe Premiere, Adobe After Effects, and Adobe GoLive can directly import PSD files and preserve many Photoshop features. TIFF Tagged Image File Format. A graphics file format developed jointly by Microsoft and Aldus as a format for desktop publishing and scanner applications. This format is used for taking files from one platform to another (Macintosh to IBM to Macintosh). It comes with LZW compression (A loss-less compression), which saves in Macintosh or IBM byte order. PICT Bit-mapped file format EPS Encapsulated Postscript Format. A picture file format that depicts postscript accurately on a computer screen display, and provides high resolution output. EPS consists of two files: A bitmap file for screen display, and the postscript code for output. JPEG Joint Photographic Experts Group. An image compression standard. It has scalable algorithm- compression factors between 7:1 and 50:1. It’s symmetrical - compresses and decompresses in the same number of operations in the same amount of time. When pixels are discarded when compressing the file exactly the same ones are not necessarily replaced when opening and decompressing the file. GIF CompuServe’s Graphics Interchange Format. For on-line services and to pass documents between other types of computers. Greyscale and Indexed colour files only with a maximum of 8 bits per pixel. 60 Photoshop The Photoshop Desktop. The Photoshop desktop consists of three main components. ✤ The menu bar, ✤ The toolbox ✤ The palettes The menu always appears at the top foreground and background colour icons, which provide access to the colour picker. The default colours icon and the switch colours icon are also in this area. If you look closely, some tools has a small black triangle in the lower right corner. This is a visual cue given to us by the programs designers to tell us through where others have a clear space. Layers allow you to have a number of images in one file. When pasting in a new selection to a file it automatically becomes a layer. If an image is made up of a stack of layers the editing capabilities are far more flexible. Individual layers may be edited separately. Once the layers are flattened (become one layer) editing becomes more difficult, because there is only one component. of the screen. Press on a menu name to access the list of commands associated with it. The commands are actions which apply to either, all of the image, or to a selection, or layer. Except for the select menu which alters a selection. Before you can apply most of these commands the computer needs to know what you wish to work with by selecting it. The toolbox contains icons for Selection, Painting & Editing tools. Each of the tools have different options in the options palettes. When a new tool is selected the options palette changes to the appropriate specifications. The tools in the upper portion of the toolbox are used for selection. The tools in the middle section of the toolbox are used for painting. The tools are connected to the brushes and colour pickers palettes as well as the options palettes. The tools in the lower portion of the toolbox have various uses. Below the tools are that there are more tools situated under this tool. Click and hold on these tools and you will be shown various other tools that maybe accessible beneath it. Photoshop Layers Layers are like animation cells, a clear acetate sheet with an image on it. These sheets [layers] can be stacked on top of each and their stacking When working on a particular part of an image you must make sure that the layer you are working on is selected. Failing to choose it is a mistake that often happens, and you find you can’t do what you wish to. Layers may be accessed either through the layers palette or the layers menu, on the menu bar. order changed around, deleted or added to [see right]. When looking down into the stack parts of some images can show 61 Opening And Saving Files On The Macintosh To open an application - Double click it’s icon in the dock found at the bottom of the screen. Opening A File With this application open, go to [ from the menu bar] file and open A dialogue box appears. At the top of the box there is either a strip with name of the application you are using, or depending on the application the last person to use the computer used, with an open folder symbol in it. This strip indicates to you which location you are in, on the hard drive of the computer. It is from here that you move around to other locations, by clicking on the strip a drop down menu appears and you click on the file or location, that you wish to go such as desktop or disks. Saving A File Go to FILE and SAVE AS At the top of the box there is a strip with the name of the last folder saved to you. This strip indicates to you what location you are in, and it is from here that you move around to other locations, eg, disks and drives. Saving There are three methods of saving : Save, Save As & Save As A Copy Save, will save changes to an already existing file - in the same location, name and file type replacing the existing file. Save As, allows you to save changes you have made - in a new location, a new name or different file type - without affecting the original file. The original file is still in its original place with no changes. Save As A Copy, allows you to save a copy in any location or the same location. Click on the strip to find your way to the desktop, where your zip or cd is located. A short cut to the desktop is to click on the button marked desktop. In the dialogue box it will now show a list of what is on the desktop. Choose the disk you wish to save to, by double clicking on it in the list. Rename your file and click on the save button. Close the file and application. 62 Colour Modes, in Photoshop & Digital Photography Colour Mode In photoshop is accessed via the Menu bar. Image>Image Mode. Greyscale Greyscale mode uses up to 256 shades of gray. Every pixel of a greyscale image has a brightness value ranging from 0 (black) to 255 (white). Greyscale values can also be measured as percentages of black ink coverage (0% is equal to white, 100% to black). Images produced using black-and-white or greyscale scanners typically are displayed in Greyscale mode. Indexed Colour Indexed Color mode produces 8-bit image files with at most 256 colors. When converting to indexed color, Photoshop builds a color lookup table (CLUT), which stores and indexes the colors in the image. If a color in the original image does not appear in the table, the program chooses the closest one or uses dithering to simulate the color using available colors. CMYK In Photoshop’s CMYK mode, each pixel is assigned a percentage value for each of the process inks. The lightest (highlight) colors are assigned small percentages of process ink colors, the darker (shadow) colors higher percentages. For example, a bright red might contain 2% cyan, 93% magenta, 90% yellow, and 0% black. In CMYK images, pure white is generated when all four components have values of 0% L.A.B. In Photoshop, the Lab Color mode has a lightness component (L) that can range from 0 to 100. In the Adobe Color Picker, the a component (greenred axis) and the b component (blueyellow axis) can range from +7 to - In the Color palette, the a component and the b component can range from +0 to -0. Channels Every Photoshop image has one or more channels, each storing information about color elements in the image. The number of default color channels in an image depends on its color mode. For example, a CMYK image has at least four channels, one each for cyan, magenta, yellow, and black information. Think of a channel as analogous to a plate in the printing process, with a separate plate applying each layer of color. RGB Photoshop’s RGB Color mode uses the RGB model, assigning an intensity value to each pixel ranging from 0 (black) to 255 (white) for each of the RGB (red, green, blue) components in a color image. For example, a bright red color might have an R value of 246, a G value of 20, and a B value of 50. When the values of all three components are equal, the result is a shade of neutral gray. When the value of all components are 255, the result is pure white; when the values are 0, pure black. 63 Photoshop The Photoshop Interface. Let’s look at some elements of the work space in Photoshop™. A quick glance shows us that the screen has a series of words running across the top, [Menu bar] a tool palette running down the left side of the screen, [Tool Palette] and a series of palettes running down the right side of the screen [Palettes]. Directly under the Menu bar is the options bar/palette. All this is modifiable to your own preferences, we will however, start with the default settings from the program, feel free to move them around as you see fit, if at any stage you wish to reset them go to [click and hold on] Window [scroll down to] Reset Palette Locations. This will reinstate the default palette settings for the program. In the world of computer texts, this series of steps is commonly written as this Go to Window>Reset Palettes Locations Photoshop’s Menu bar The menu bar always appears at the top of the screen. Press on a menu name to access the list of commands associated with it. The commands are actions which apply to either, all of the image, or to a selection, or layer. Except for the select menu which alters a selection. Before you can apply most of these commands the computer needs to know what you wish to work with by selecting it. The most important of these is the help menu, if you get stuck or need help at any time, this will help you solve problems and pages can even be printed out for future reference. Tool palette The tool box contains icons for SELECTION, PAINTING and EDITING tools. Each of the tools have different options in the options palettes. [Situated under the Menu bar]. When a new tool is selected the options palette changes to the appropriate specifications. The tools in the upper portion of the tool box are used for selection. The tools in the middle section of the tool box are used for painting. The tools are connected to the brushes and colour pickers palettes as well as the options palettes. The tools in the lower portion of the tool box have various uses. Below the tools are foreground and background colour icons, which provide access to the colour picker. The default colours icon and the switch colours icon are also in this area. If you look closely, some tools have a small black triangle in the lower right corner. This is a visual cue given to us by the programs designers to tell us that there are more tools situated under this tool. Click and hold on these tools and you will be shown various other tools that maybe accessible beneath it. Photoshop Layers/Layers Palette Layers are like animation cells, a clear acetate sheet with an image on it. These sheets [layers] can be stacked on top of each and their stacking order changed around, deleted or added to [see right]. When looking down into the stack parts of some images can show through where others have a clear space. Layers allow you to have a number of images in one file. When pasting in a new selection to a file it automatically becomes a layer. If an image is made up of a stack of layers the editing capabilities are far more flexible. The Layers palette lists all layers, layer sets, and layer effects in an image. You can accomplish many tasks such as creating, hiding, displaying, copying, and deleting layers using the buttons in the Layers palette. You can access additional commands and options in the Layers palette menu and the Layers menu. Individual layers may be edited separately. Once the layers are flattened (become one layer) editing becomes more difficult, because there is only one component. When working on a particular part of an image you must make sure that the layer you are working on is selected. Failing to choose it is a mistake that often happens, and you find you can’t do what you wish to. Layers may be accessed either through the layers palette or the layers menu, on the menu bar. Paths Palette This is the palette that show you any paths you have made, useful for making complex selections and storing them. The Paths palette lists the name and a thumbnail image of each saved path, the current work path, and the current vector mask. Decreasing the size of thumbnails or turning them off lets you list more paths in the palette, and turning thumbnails off can improve performance. To view a path, you must first select it in the Paths palette. 64 Channels palette. This is where all the information for each images channels is displayed, as well as extra channels created by Alpha Masks. The Channels palette lets you create and manage channels and monitor the effects of editing. The palette lists all channels in the image composite channel first (for RGB, CMYK, and Lab images), then individual color channels,spot color channels, and finally alpha channels. A thumbnail of the channel’s contents appears to the left of the channel name; the thumbnail automatically updates as you edit the channel. Info Palette. This palette can be used like a densitometer and is indispensable when measuring certain elements in an image such as colour, density and size. You can use the Info palette and the Color palette to see the color value of pixels as you make color corrections. This feedback is useful while you make color adjustments. For instance, referring to the color values can help when neutralizing a color cast or can alert you to whether a color is saturated. When you work with a color adjustment dialog box, the Info palette displays two sets of color values for the pixels under the pointer. The value in the left column is the original color value. The value in the right column is the color value after the adjustment is made. History Palette The History palette lets you jump to any recent state of the image created during the current working session. Each time you apply a change to an image, the new state of that image is added to the palette. For example, if you select, paint, and rotate part of an image, each of those states is listed separately in the palette. You can then select any of the states, and the image will revert to how it looked when that change was first applied. You can then work from that state Histogram Palette The Histogram palette offers many options for viewing tonal and color information about an image. By default, the histogram displays the tonal range of the entire image. To display histogram data for a portion of the image, first select that portion. The Options Bar/Palette Most tools have options that are displayed in the options bar. The options bar is context sensitive and changes as different tools are selected. Some settings in the options bar are common to several tools (such as painting modes and opacity), and some are specific to one tool (such as the Auto Erase setting for the Pencil tool).You can move the options bar anywhere in the work area using the gripper bar, and dock it at the top or bottom of the screen. Tool tips appear when you hold the pointer over a tool. Actions Palette You use the Actions palette to record, play, edit, and delete individual actions. This palette also lets you save and load action files. In Photoshop, actions are grouped into sets you can create new sets to better organize your actions. Navigator Palette If the entire image is not visible in the document window, you can navigate to bring another area of the image into view. In Photoshop, you can also use the Navigator palette to quickly change the view of an image. 65 A Closer Look At The Photoshop Tool Bar Far right is the tool bar with some of the more common tools shown.Some tools have a small black triangle on the bottom right corner They show what other tools are under the existing tool when the small black arrow is clicked on and held. Also if you hover the mouse over each tool you will get the listing of each tool’s name and it’s shortcut key They are in order from top to bottom. Basic Selection Tools Rectangular marquee tool, Elliptical marquee tool, horizontal single pixel tool, vertical single pixel tool. All used to make simple selections based on the shape of the tool chosen. Advanced Selection Tools Free hand Lasso Tool, Polygon Lasso tool, Magnetic lasso tool. Used to make more complicated selections than the Marquee tool based on freehand drawing. Burn Dodge & Sponge tools. Burn and dodge are used to darken or lighten local areas of an image, the sponge tool for desaturation, locally. The Photoshop Toolbar Basic Cloning Tools This are simple tools that copy pixels directly from one are to another Intelligent Cloning/Healing Tools Rubber stamp tool, rubber stamp pattern tool. Used to repair or clone areas of an image, in a way that mimics the surrounding area that is being repaired. 66 Scanning It is important to tailor your scan to the desired quality of the final output of the image. If the image is to be used only on the screen. The resolution of the image need only be 72 ppi, the same as the screen. If the image is to be output to a printer the resolution depends on the quality of output you need as well as the resolution of the printer and the size of the original document to the scanned image. Another consideration would be the file size as it directly affects the time required for the printer to process the image. Screen Frequency, also known as screen ruling, refers to the number of halftone cells per inch in the halftone screen used to print a greyscale image or colour separation. Screen frequency is measured in lines per inch [lpi]. The detail in a printed image results from a combination of resolution and screen frequency. To produce a quality halftone image, the image resolution should be twice the lpi value of the halftone screen used to print the image. A screen ruling of 177 lpi has more detail than 85 lpi. Typical screens for common usage would be 65# for newspaper, 85# for small offset printing, 100# for medium black and white, 150# for normal quality process colour printing. Scanning a general overview. Software varies from scanner to scanner, so it is difficult to document all scanner interfaces. There are however several consistent sets of value that need to paid attention to, sometimes known as, Input Values. The settings that are important are:Output size ◦ Bit Depth ◦ Resolution ◦ Screen resolution should be at 72 dpi, the lowest common denominator available world wide, this also applies to CD Rom. If you send the file to any other “Output device” consult with the Bureau/Laboratory that is outputting the file. Always scan enough data to make a print the size you want it to be. Always scan at a bit depth of 48 bits for colour and 16 bit for Black & White. Always set the resolution for the appropriate device that you are sending your output to. Some output devices are, Screen/ Monitor, Inkjet, CD ROm, Pegasus, Lambda. All have their own output resolutions. We use Inkjet printers here at PIC and they require a resolution of either 180 dpi, or 360 dpi, other printers may require different resolutions so consult a Teacher if you’re not sure. 67 Scanning Guide, or how big should my scan be? Physical Sizes & File sizes When scanning a negative, slide or other art work, before turning on a computer or scanner, answer the following questions. How big do I want the final piece to be? Where am I sending the image to be output? What is the resolution of the output device I am sending too? Is it a colour image? What bit depth do I need to have the image set to for the output device? Answering these questions will help you read the table below to scan in the best possible image for the best possible output. Use the scanning interface to then get the needed values for your output. Digital files [Sizes in Megabytes]* Physical Output Size 5 x7 8 x 10 11 x 14 12 x 16 A4 21x29 cm A3 29x42cm Resolution 12 Bit colour 24 bit colour 8 bit b&w 16 bit b&w 180 3.24 16.49 1.08 2.16 360 13 26 4.33 8.65 300 9 18 3m 6 180 7.42 14.8 2.47 4.94 360 29.7 59.3 9.89 19.8 300 20 41 6.8 13.7 180 14.3 28.6 4.76 9.52 360 57.1 114.2 19 38.1 300 39.7 79.3 13.2 26.4 180 17.8 35.6 5.93 11.9 360 71.2 142.4 23.7 47.5 300 49.4 98.9 16.5 33 180 8.75 17.5 2.92 5.83 360 35 70 11.7 23.3 300 24.3 48.6 8.1 16.2 180 17.5 35.0 5.83 11.7 360 70 140 23 46.7 300 48.6 97.2 16.2 32.4 As any good image maker knows an image can be made to look better or suit your intentions with some manipulation. The degree of manipulation and desired final look of the image is limited only by your imagination when using a program like ‘Adobe Photoshop™’. Some of the approaches used in the traditional darkroom can be easily applied in this software package. Techniques like burning and dodging, bleaching, toning, hand colouring, spotting, local contrast control and overall contrast control are all easily achieved in ‘Photoshop™’. Surprisingly selections are not always the best way to undertake these tasks, and we will show you a few tips on how to achieve this. Move the mouse over the tool bar if you leave the mouse there for a moment or two the name of the tool will pop out as well as the shortcut key to access it. Look art the picture displayed with in the dialog box [right], If there are gaps on the ends of the image drag these all inwards, [check each channel by holding down on the channels drop down menu and drag these inward], and click ok. Save this image ready to begin your creation. Levels Depending on the job at hand will depend on where the tool we choose. However as a first move it’s often a good idea to check the levels of the scan/digital file/capture you have just completed. Go to image> adjust>levels 69 What and How to Edit in Photoshop? Photoshop is a powerful industry standard image editing tool. Like all tools of this nature “with great power Spend quality time with your images first, use a tool like Bridge, or Lightroom to sort and organise, then comes great responsibility”. Photoshop is a destructive editing tool that destroys pixels as it works, as a consequence to produce the best prints we can, we must use everything when you are happy with your selection study each image closely use tools like the eye dropper tool to measure key areas in your image. Key areas could be:Highlights, the bright areas Shadows the dark areas Skin tones, or any area you feel is important to the final piece and what you are trying to say The zone ruler will help you decide what areas need attention if yo need to make a print as some areas may look ok on screen but be blocked up at our disposal to minimise this. Fortunately photoshop provides the very tool to allow this. Adjustment Layers. Anything you could possibly want to manipulate in an image in photoshop can be done using either adjustment layers or layer masks, this includes but is not limited to: Brightness/contrast ✴ Levels ✴ Curves ✴ Montage ✴ Toning ✴ Spot Colour How to commence editing an image in photoshop depends primarily on your own ideas and vision in how you want the image to print, and to a lesser extent by the limitations imposed by on paper, particularly values under 25RGB or over 252 RGB. For specific instructions on how to use these tools refer to the section of the book for each Remember Photoshop is a pixel editing program and destroys pixels as you work. A series of adjustment layers used to manipulate an image to our intended vision. the output media, and by media I mean paper or screen for example. A screen has more contrast and is backlit making colours rich and delightful to look at. Paper prints on the other hand have other outside influences that change the way our images look, just choosing the wrong type of media in the print dialog box will have drastic affects on how our pictures will look. 70 Creating a Zone Ruler inPhotoshop Follow these instructions, 1.

Many devotees of photography have romantic notions when they set up studios in their homes, in the garage, in fact, any space can become a possibility when you are keen to follow your passion. However, it is this approach that creates a serious risk to the user. Without question working with powered light sources is the most danderous part of a photographer’s job. It is important therefore that you develop good work practices and never allow familiarity to lead to complacency and poor practices. Electricity is dangerous. It can kill you. It cannot be stressed strongly enough that when designing your own studio, that the lighting equipment and studio power supply be either installed, or checked in the case of existing supply, by a qualified and licensed electrician. Consideration must be given to the total number of amps drawn by lamps, to avoid exceeding the fuse rating. Remember:This means that one 250 V socket fused at 13 A will only power 3250 W of lighting. When servicing the equipment check that your lighting units and plugs are all properly grounded (earthed). Ensure extension leads are placed so as not to become an intrusion to movement and possible accident.. Finally, don’t jolt lamps while they are hot - especially tungsten-halogen types which easily short out their closely coiled filaments, and are expensive to replace. If something goes wrong with your equipment never attempt to repair lights or wiring unless you are absolutely confident that you know what you are doing. • • • • • • • • • Always turn off the power and disconnect the cable before changing a globe.

Ensure adequate ventilation of the studio area. Equipment / Essentials • An area devoid of external light sources, preferably a room with no windows or one capable of being darkened by the use of heavy curtains or blinds. • An AC power supply with circuit breakers, distribution boards and extension cables. • Camera, lenses, accessories • Two 500W flood lights (diffuse tungsten light source), and associated stands. • Heavy duty tripod, preferably with rising central column or arm. • Hand held light meter capable of measuring flash and ambient light. • Film and Polaroid, Memory Cards. • 18% grey card. • First Aid Kit. • Appropriate Fire Extinguisher. • A system of stands and poles from which to hang background material. • Stands (C-stands, vertical stands with adjustable arm) to support reflectors, diffusion material, colour filtration. • Table top. • Preparation or work bench. • Gaffer tape, heat resistant tracing paper, reflectors, Stanley knife, heat resistant gloves. 79 Studio Book. Learning Outcome The purpose of this exercise is to assist you in the production of a studio book that forms a tangible base in which to experience, accumulate props and ideas, having time to previsualise sets/concepts you may intend to photograph. Hence the importance of the setup and the maintenance of your studio book lies within the context procedure of Plan > Enactment > Record Assessment Criteria You are required to present your studio book to provide evidence of your ability to: 4.1 Ensure your work space is adequate for purposes and available for duration of shoot. 4.2 Select desired background, appropriate to mood and concept 4.3 Construct any necessary supports. 4.4 Ensure all necessary props are available. 4.5 Determine legal responsibilities. Method You are required to maintain a book that records your learning experiences including: 1. Studio - Equipment and Layout. 2. Lecture notes, assignments, demonstrations, your personal research, workshops etc. 3. Development and translation of your ideas / concepts in visual form sketches and diagrams. 4. Your PLAN for each shoot. Within the studio procedure, technical considerations must be documented, planned and adhered to, especially while you are at this stage in your learning curve. 5. Your ENACTMENT for each shoot. Sketches and diagrams of all equipment set up (lighting, camera positions and props) must be clearly and accurately recorded. The success of the shoot will hinge on how accurately the studio book procedure has been followed through, and will act as a future reference. 6. Your RECORD for each shoot. Exposure, proofs and examples. (Recording your learning experiences allows to evaluate your progress more accurately and assists in developing both ideas and skills). 80 Studio Lighting In the early days of photography the main function of subject lighting was to give enough illumination to get a reasonably short exposure. Today, faster lenses and films allow you far more options, so that lighting can be used to express ( or repress ) chosen aspects such as texture, form, detail and mood. The way you select and organise your lighting is highly creative and individualistic - in fact you will find lighting one of the most stimulating, exciting aspects of picture making. The illumination of your subject relies on the characteristics of light including its straight line of travel, effect of size of source, diffusion, reflection etc. You can use each of them in various practical ways to alter the appearance of a subject, and they apply to any light source, whether the sun, a flashgun, a studio lamp or even a candle. By far the best place to learn lighting is in the studio. Once you have experienced how lighting works with everything under your control, it is easier to understand the cause and effect of the many ‘existing light’ situations you will meet. Light is light, and the image is composed of the effects of reflected light whether it is natural or “artificial.” Within the natural world the light is used as found, with few exceptions, in a process that is essentially analytic. The use of artificial light, on the other hand, may be thought of as a process of synthesis, where you are free to control the amount and nature of the light and direct it as you wish Light in relation to photography, is: Absence of darkness. You do need the activity of light in order to see. Without this activity all would be dark. Contrary to painting, in studio photography you do not start with a white piece of canvas but with a black one. The moment you shine a light onto your subject you bring into view some details of that subject. How much and which details will come into view is strictly related to the position, and the quality, of the light-source you are using.The simplest form of light is the: Point light-source. You know this light very well because it is equivalent to sun-light on a cloudless day. give you relief, all you would be able to see would be two-dimensional shapes. For all intent and purpose, light, in relation to photography, travels in straight lines. A Point light-source will only illuminate (remove darkness from) those surfaces that are exposed to it. Not being able to go around corners this light will ‘leave darkness’ on all surfaces that are not directly facing it. This we call creating a shadow. This is very important because, by controlling the value, shape and intensity of those shadows, you can create the three-dimensionality and the mood you want. You can control the properties of light in different ways but the underpinning principle is: Light creates shadows Shadows create dimension Imagine a model draped in white frontally lit, with a white backdrop. With all the shadows falling behind the model and out of sight, you have a scene with the same visual values right across the frame where the model is barely visible. By moving your light source to the side you would bring the shadows into full view on the opposite side to provide contrast for your eyes to distinguish. The shape and texture of the model would now be quite visible. As you can see Shadows are very important because they help you draw your subject. It is a fundamental principle: you give value to your highlights by the placement of your shadows. It is the shadows that make you see in three-dimensions. Without shadows to 81 Exposure / Light Meter Studio photographers have traditionally made use of the incidentlight exposure meters, both because their subjects may be too small to read with a general-purpose reflected light meter and as a means of measuring separate light sources. The incident meter is increasingly being replaced by the spot meter because of the greater precision it affords in maintaining full control of the subject contrast and luminance values. We will study this later in depth but now we will look at an overview of several systems used for accurate film exposure. Each system works well, in most conditions, for either throughthe-lens or hand-held light meters. Incident And Reflected Light When light strikes a surface, it can be transmitted through it, absorbed, or reflected. If the substance is transparent, like window glass, most of the light will be transmitted, although some is inevitably lost to reflection and absorption. A translucent material, like white tissue paper, has a considerably lower transmission and diffuses the light passing through it, while opaque substances transmit no visible radiation. The proportion of light that is transmitted, absorbed, or reflected is often a function of wavelength; if some wavelengths are transmitted or reflected in greater amounts than others, we perceive a characteristic colour for that object. Incident Light Objects that we see and photograph are illuminated by incident light falling on them from sun and sky, or from artificial light sources. The incident light, or illuminance, can be measured in units of foot-candles, which originally referred to the illumination provided by a “standard candle” located one foot from a surface. An incident light meter is used to measure the amount of light falling on a subject as one means of determining camera exposure. Such meters contain a diffusing hemisphere or disc over the photocell to “average” all the light falling on them. The incident light meter is held at the subject and usually directed toward the camera, so that all light incident upon the side of the subject being photographed is integrated in the single reading. For an incident-light reading, you slip the white plastic diffusing dome over the meter’s measuring window. Then the meter is held in the same lighting conditions as the subject, pointing towards the camera. It therefore takes into account all the (scrambled) light reading the subject, rather than the subject’s reflective properties. The plastic dome transmits 18% of the light, so you end up with much the same situation as a grey-card reading, but in a more convenient form. Reflected Light. Reflected light is the light that reflects off the subject and bounces back to the meter. To read reflected light, the meter is pointed directly at the subject. Most light meters read reflected light. This is undertaken with the invercone removed. The meter’s light sensitive cell has an angle of acceptance approximately equivalent to a normal lens. With a spot meter attachment this angle can be reduced to five degrees for precise measurements within the subject. The exposure that the meter recommends is an average of the reflected light from the light and dark tones present. When light and dark tones are of equal distribution within the frame this average reading is suitable for exposure. It must be remembered the meter assumes everything reflects light at the same level as an 18% grey card. The total luminance of a surface is determined by the amount of light incident upon it and a property of the surface known as its reflectance. The reflectance of a substance is expressed as a percentage that indicates the proportion of incident light that is reflected by that material. It is because of differences in reflectance that we perceive some objects as “white” and others as “black,” regardless of whether we are viewing them under bright daylight or low-level illumination. A deep black material may reflect less than 2% of incident light, while a white substance may reflect over 95%; no material, however, has 100% reflectance since some light is inevitably lost to absorption and scatter. Tonal Contrast Leonardo Da Vinci was the first one to recognise and apply the play of light and shadows that in painting is called Chiaroscuro (light and dark). In Photography we call it Tonal Contrast. The shadows cast by a particular light-source will always have the same quality and intensity; quite apart from the position of the light-source in relation to the subject and the camera. You can however control the shadows’ visibility by changing the position of the light-source relative to the subject and the camera, as you have seen in the example of the white model. The Point light-source casts welldefined shadows of high intensity. This gives your subject the greatest degree of dimension (relief) because of the high level of contrast between the shadows and the highlights. On an overcast day a scene would definitely not have the same level of contrast and would appear somewhat softer (tonally flatter) than the same scene on a sunny, cloudless day. The main reason for the softer appearance is due to the change in quality (size) of the light-source. Shadow’s Edge Transfer A bank of thin clouds over the sun acts very much like a diffuser. It scatters the highly directional rays of the sun across the sky making the entire canopy a huge, multi-directional light source. In this situation all the surfaces not facing the sun directly will still receive a degree of illumination from the edges of the clouds. This reduces the 82 intensity the shadows would have had on a sunny, cloudless day. Increasing the size of your light source has also an effect on the quality of your shadows’ edge. While the Point of light-source creates shadows with a sharp, well defined edge, a broader light-source, being more diffused, will give your shadows a softer, undefined edge.The quality of the line separating the shadows and the highlights is known, in photography, as the Shadows’ Edge Transfer. The Sun and the Overcast Sky are the two extremes types of light sources: The point light source (the sun) and the broadest, diffused one (overcast sky). Any size in between these two will offer you different qualities and characteristics that you can exploit to your advantage. The choice of size of a light-source will then be determined by the visual and emotional effect you want to create. The ‘drawing qualities’ of a smaller light-source will chisel your subject, as in painting, with minute, very accurate and definite shadows. A larger lightsource will render the same subject in broader, more impressionistic strokes having less definition in its shadows. 83 Studio - Equipment & Layout Learning Outcome This exercise is designed to help the student to learn where all the equipment is located and what function it has within the boundaries of the studio. Method. You are required to make a sketch of the studio layout, and to label all of the equipment using a sketch and description of the part and its function. During the lesson, make rough sketches and then transfer these into your Studio Book. Work Requirement. This is to be presented for assessment in your studio book as being your introduction to the studio. Specularity As we have said, light, for all intent and purpose, travels in straight lines. From any point within the light source a straight line of light (ray) will travel to illuminate a surface. Once that ray hits the surface it is reflected back at the same angle of incidence. Some of the light rays will be absorbed by the surface’s qualities, that is the reason why you can see different tonal values as well as colours - while the rest will be reflected back to the eyes. A smooth surface: the body of a car, the smooth surface of a lake, the shiny skin on a sweaty face, etc. works like a mirror and will reflect all or most of the light back to the eyes. A rough surface: the sand on a beach; the sandstone bricks of a building; the matt surface of a face full of make-up, etc. works like a diffuser and will scatter most of the light’s rays in all directions. The rays coming back to the eyes will not have the same concentrated intensity. A rough or matt surface is made up of infinitesimal smaller surfaces not facing in the same direction as the overall surface, very much like pebbles on a beach. Although the beach is facing the sky at a slight angle, each pebble has its own orientation to the sky. Obviously the pebbles will reflect the rays of light according to their own orientation and not necessarily to the orientation of the beach. In turn the surface of each pebble will scatter the light again according to its own peculiarities. Characteristics of Lighting. There are three features of lighting (black & white) to bear in mind: quality, direction contrast. Start by looking at these one at a time, then see how they are combined in different kinds of equipment and techniques. Quality of Lighting: This is mostly concerned with the type of shadow the light source causes objects to cast - hard and clear cut, or soft and graduated. Lighting quality depends on the size of the source relative to its distance from the subject. Hardest light comes from the most compact, point-like source, such as a spotlight or projector bulb, a small flashgun, a clear glass domestic lamp, a lighted match or direct light from the sun or moon. The sun however, although “compact”, is a very bright light source, providing a huge variety of light qualities. These light qualities will depend on latitude, time of day, atmospheric and climatic conditions. (The sun and moon are vast in size, but because of their immense distances they form relatively small, compact sources in our sky.) All these light sources are very different in other respects, such as intensity, but you will find they all give sharp-edged shadows. bounced from this for subject illumination. The opposite conversion is also possible. You can make a large soft source give hard illumination by blocking it off with black card leaving only a small hole. Indoors, if you almost close opaque window blinds you can produce fairly hard light even when the sky outside is overcast. The size and closeness of your light source also change the character of reflections from gloss-surfaced subjects. A hard light source gives a small, brilliant highlight. Typical of this is the catchlight in the eyes of a portrait. Soft light gives a paler, spread highlight, which may sometimes dilute the underlying colour of an entire surface. Softest light comes from a large, enveloping source. You can make any hard light source give soft lighting by placing a large sheet of diffusing material, such as tracing paper, between it and the subject. The larger and closer your diffuser is to your subject the softer the lighting. Similarly you can direct a hard source on to a large matt reflector such as a whitelined umbrella, card, the ceiling or a nearby wall, and use only the light 84 Sekonic Handheld Meter 1.

Often this means that when you expose to get detail in the featureless, even though you could these changes of direction work with see details there at the time. both hard and soft light sources, but Alternatively, exposing to suit they are more marked with hard light because of its sharp-edged shadows due to increased brightness contrast range. shadows ‘burns out’ details in the lighter areas. The problem is greatest with side or top lighting, although the lit surfaces then show excellent form and texture there are often large When another light is added to your lighting set up, you need to determine the balance of exposure between the shadow areas. If you want to improve shadow detail you could add an extra direct light from the opposite direction lights. You need to choose which light ( be careful not to form an extra set of is to the main light and which are to cross-shadows which can be be the fill lights. Refer to lighting ratios confusing and unnatural ). Another solution is to use a reflector board near the subject’s shadow side to 86 High Key Lighting in the studio. High key portraits have predominantly lighter tones, with very little below Zone V. resulting in an image that has a white background and light face with no shadows, the only dark areas are the outline of the eyes and mouth.The way to get this look is through a combination of overexposure, plus development and diffuse lighting. The Setup A white background that is illuminated separately from the subject. Cutters between these lights and the subject to prevent flare and to prevent light falling on the subject. Position the subject a few meters in front of the background making sure no light from the background lights are falling on the subject. Position two lights, each with reflective umbrellas, at a 45˚ angle to the subject.Use reflectors if there are any shadows still on the face. Take an incident meter reading from the subject. Take reflective readings from various parts of the background and ensure that it is even and 3.5 stops brighter than the incident reading taken at the subject. The incident reading is used as a reference to set your aperture and shutter speed. Overexpose by two stops to push all the values up (i.e. if the reading was f11 @ 1/60 second, expose at 5.6 @ 1/60 second) and when processing give the film +1 development to push up the highlight values. 87 Low Key Lighting in The Studio. Low key portraits have mostly darker tones. Black background and dark tones on the face with a few specular highlights. The look can be similar to the film genre of film noir, Mostly dark with only a few selected areas highlighted. Generally the setup is this, a black background place one or two spots to the rear and side of the subject. This light is for the highlights, without any other lights the subjects face will be in deep shadow. A little illumination is needed to reveal more detail. Reflected or diffused light needs to be placed to the front of the subject. There are two qualities of light being used here. The spot, which is illuminating the highlight, is a harder light than the front reflected lights. The Setup For the purpose of learning this technique we will use a specific lighting setup. A black background. Position the subject a couple of meters in front of the background so that the lights on the subject don’t illuminate the background. Place a spot at 45˚ to the left at the rear of the subject. Place a cutter between the spot and the subject. Position two lights with reflective umbrellas at 45˚to the front of the subject. Take an incident reading from the spot. Take an incident reading from the front lights. Make the left light the same reading as the rear spot, and the right light one stop less (i.e. if the spot reads f8@ 1/60 make the left front light f8 @ 1/60 and the right front light f11 @ 1/60) 88 Flash photography, a brief history In the 1850’s it was discovered that magnesium burned with an intense white light, a characteristic that early photographers were quick to adopt for “seeing in the dark”. From the 1880’s an explosive mixture of magnesium cut with gun cotton was used to illuminate night scenes. The shutter was opened on “b” or bulb and the powder touched off, emitting a flash of light and distinctive clouds of choking smoke. Flashbulbs became smaller, first with “peanut” bulbs filled with finely spun zirconium wire, then flashcubes [Four bulbs in one rotating head, each with it’s own reflector]. The father of electronic flash was Dr. Harold Edgerton of the Massachusetts Institute of Technology, [M I T], who used flash and precisely timed stroboscopic lights to freeze bullets and capture sequential images of humans and animals in motion. In 1925, Dr. Paul Vierkotter invented the flashbulb, a magnesium wire encased in glass, which was triggered by passing a low voltage current through it. Reflective foil was subsequently added, and parabolic reflectors placed behind the bulb to improve the direction of the flash’s output. A high voltage charge, collected in a capacitor, passes through an inert gas- filled tube when the shutter is released. The brilliant flash of light that results has a very short duration, typically 1/500 to 1/1000 of a second, [compared with around 1/60 of a second for type “M” flash bulbs] which effectively becomes the fastest allowable shutter speed. The light output is at a colour temperature, of around 5500 kelvin the same as daylight. The great advantage of these lightweight portable units is their main types: The manual flash, that fires at full or half power and requires calculation for correct exposure settings. The automatic flash that once set to a designated f-number, calculates the flash duration from light reflected off the subject. The dedicated flash unit. These flash units link the camera’s metering systems with the light output to give extremely accurate exposure in most lighting conditions Measuring Exposure, for Flash Control and exposure of electronic flash differs in several ways from continuous light source techniques. When a flash unit is switched on, a steady current is drawn into electrical storage tanks, called capacitors, which cause a ready signal to appear when fully charged. The exposure settings for the camera are dependent upon the distance between the subject and flash and the film speed used, the closer the flash or more sensitive the film the smaller the aperture that is used, conversely the less sensitive the film, or the further away the flash from the subject the wider the aperture used. Shutter speeds do not affect the exposure, however, most camera manufacturers have a flash sync speed marked on the shutter speed dial, usually marked in red, this is the fastest shutter speed you can use, you may use lower for creative effects but a higher shutter will result usually in half exposed or unexposed negs. How Electronic Flash Works Most electronic flash units consist of a flash tube set into a reflector, batteries, and electrical circuits that enable the flash to go off on command. Also, there is an oscillator that converts the low voltage of the batteries to a much higher voltage (typically 450 volts), and a capacitor that accumulates and holds that high voltage electricity. Additionally, on automatic units, internal electronics can control the power output of the flash in response to a sensor that measures the flash light reflecting back from the subject. Such sensors are found on the front of the flash, or may be inside the camera and electronically connected to the flash. When you trip the camera shutter, a switch in the camera simultaneously fires the flash. At that moment, electrical energy stored in the flash unit capacitor is released in a sudden burst of power through the flash tube, creating a flash of light. The flash tube has an extremely long life expectancy. It can fire thousands of bursts before wearing out. Its burst of intense light is so short (usually 1/1,000 of a second or faster) that fast action can be frozen easily in most picture-taking situations. Flash Photography Depends On Distance When we photograph with available light, camera-to-subject distance is a concern only in regard to focusing and composition; it has no bearing on the amount of light that reaches the film, and therefore does not affect the lens opening or shutter settings. In flash photography, subject distance - or, more accurately, flash-to-subject distance - is a much more significant factor. Distance must always be considered when taking flash pictures because of the way light propagates. The burst of light generated by the flash unit immediately begins to spread out as it leaves the flash tube. The farther it travels, the more it spreads out and the more its intensity decreases. When the subject is near the flash, the light has not spread out very much and is therefore very bright; in fact under some circumstances, it may be too bright. Conversely, a distant subject will receive much dimmer light from the same flash. As a consequence of this, when the flash is set on manual, you must set the lens to an aperture appropriate for the light level found at each flash-tosubject distance. With automatic flash, each lens aperture automatically produces correctly exposed flash pictures, but only over a prescribed range of distances. As you change apertures, the near and far limits of that range shift.While this may sound somewhat complicated, it is extremely easy in practice. In most cases, all necessary information is right on the flash, and absolutely no calculations are required. Manual Mode, for Flash Photography. When you operate your flash in its manual mode, it puts out the same amount of light, for the same duration, each time it is fired. With most flash units, that amount of light is also the maximum of which the equipment is capable. (On some models, you can set the power in manual mode to 1/2, 1/4, and less, of maximum.) In manual mode, you must use a different lens aperture for each flashto-subject distance. Manual operation of a flash is appropriate: • when you wish to exceed the distance limits available with automatic exposure; • when you feel the automatic sensor may produce erroneous exposures due to unusual subject tone or placement; • when the flash is removed from the camera for direct, side, or backlighting and the automatic sensor cannot be placed near the camera lens; • when you are using more than one flash unit that is not designed for automatic, multiple flash operation. Of course manual operation is required with most studio size flash equipment and other units that do not have automatic sensors. To use your flash on MANUAL, it must be set to “M”. Using the Metz 45 in Automatic Mode General: When a flash is fired the sensor built into the flash unit measures the light reflected from the subject and quenches the flash as soon as the right quantity of light has been received. The following should be observed when taking flash shots in automatic mode: Make sure that the film speed is set properly. Heed that the subject is within the working range of the automatic aperture. For a good flash result the aperture selected on the camera lens must be identical to the auto working aperture on the flash gun. Selection Of Automatic Mode: Set the film speed setting knob on the aperture calculator dial such that the orange arrow points to the sensitivity of the film used. The aperture calculator dial allows 5 auto settings. Be careful to lock the dial in place. In between settings are not possible. On the interior scale, the orange coloured mark “N” indicates the f stop to be selected on the camera. On the two exterior scales, it shows the maximum operating ranges in meter and feet. When a wide angle diffuser is used, the orange coloured mark “W” on the aperture calculator dial indicates the maximum operating range. Auto Working Ranges: Each of the automatic apertures has a specific auto working range. EXAMPLE: 0.5m to 4m (1,6ft to 13ft) 0.5m to 5.5m (1,6ft to 18ft) 0.7m to 8m (2,3ft to 26ft) 1.0m to 11m (3,3ft to 36ft) 1.5m to 16m (5,0ft to 52ft) Exceeding the upper limit of the auto working range may result in underexposure, falling below the lower limit will produce overexposure. Any subject lying between the upper and lower limits of the operating range will be measured by the flash unit’s automatic system and correctly exposed (the limits given for the operating ranges do not apply to bounce flashing. As the working ranges overlap you very often have the facility of selecting the optimum aperture for the composition of the picture. All given distances are flashto-subject distances. The camera-tosubject distance may be different. The best auto aperture for a specific picture-taking situation is dependent on the required operating range and the desired depth-of-field. A lower fnumber will reduce the depth-of-field. Lower f-numbers are used whenever the background should be out-offocus in order to stress the foreground. For standard pictures, selection of the medium auto setting is recommended. When the ISO 100/21 film is used, for example, the working aperture is f/5.6. The operating range then lies between 0.7m to 8m (2ft to 26ft) AUTO CHECK illumination of the auto check indicator tells you that the exposure was correct. This feature is very useful in bounce flash applications for which the given working ranges do not apply. The firing of a trial flash by operation of the manual firing button (holding the flash unit as for normal photography) enables you to find out if the available light output is sufficient for the aperture selected. If the auto check indicator fails to light up upon firing a trial flash stop the unit down to the next smaller f-number or reduce the distance to the reflecting subject. Then fire another trial flash. 90 Automatic Flash Mode Examples: Example 1: Flash-to-subject distance: 2.5m (8ft) Film speed: ISO 100/21 Proceed as follows: Set the film speed. As the flash-to-subject distance is shorter than the maximum distances of all 5 auto working apertures and longer than the minimum distances, you have a choice of selecting any one of the 5 apertures. Because of the better depth of field you will decide in favour of aperture f11. Set the index mark “N” on the calculator dial to aperture f11. Switch on unit. The unit is ready for flashing when the flash ready lamp lights up. Example 2: Flash-to-subject distance: 6 m (20 ft) Film speed: ISO 100/21 Proceed as follows: Set the film speed. The flash-to-subject distance of 6m allows the use of apertures f5.6 - f4 f2.8 taking the maximum working ranges into account. Since you desire a shallow depth-offield you will decide in favour of aperture f2.8. Set the index mark “N” on the calculator dial to aperture f2.8. Switch on unit. The unit is ready for flashing when the flash ready lamp lights up. Fill In Flash Although flash is primarily considered a tool for lighting indoor scenes where ambient light is too dim for successful existing-light photography, you’ll find it a useful and even exciting addition outdoors in the day time or at night. Compared with the human eye, all films have considerably less ability to record detail simultaneously in both very dark shadows and very bright highlight areas. This limitation is somewhat more pronounced in slide films than in negative materials. Flash can be used to brighten shadow areas so that details become apparent. Flash can also become a creative tool to tone down surroundings and spotlight subjects. to record on film as a silhouette. Fill-in flash helps to balance exposure between background and subject. Outdoor lighting can often be improved with the judicious use of your electronic flash unit. Particularly in a backlighted situation, you’ll find that if you expose for the background, your subject becomes a nearsilhouette. If you expose for the subject in shadow, the background will become overexposed. The answer is to set your exposure for the background and add some flash to brighten the shadows on your subject. Another case for fill-in flash occurs when your subject is located near a bright light source, such as a lamp or window. When exposure is correct for the subject the background is washed out, and often the subject contrast is noticeably decreased by lens flare. On the other hand, exposing properly for the bright light causes the subject 91 Guide Number Table to Determine Flash Exposure Manual Mode In the man ual mode, the setting of the camera aperture is de- 66 Setting and Determining the camera aperture - . o Camera Aperture 92 Electronic Flash Assignments Assignment 1 Portraits using flash Shutter Speed Must Be Set To Sync With Flash K1000 Sync is 1/60 Exposure A Direct Flash ( attached to camera) 1.

Exposure using Flash Meter Basic Off-camera Operation Removing your flash unit from its customary direct camera connection offers myriad possibilities for pleasing effects. On camera flash provides a flat illumination that can be rather harsh. When your flash is off the camera, you create illumination that gives shadows for form or that is reflected for a softer quality. Off-Camera Flash While on camera flash is fast and convenient, considerable improvement in modeling – subject shape, texture, and general appearance created by the light – frequently occurs when you position the flash away from the camera. The goal is to have the light falling on the subject more from the side, top, or even bottom than directly from the front. Bounce Flash Direct light sometimes produces hard shadows. This can be avoided by bouncing the flash. For this purpose, the reflector is tilted upwards so that the light is reflected off the ceiling or a suitable reflective surface to give soft overall illumination. The reflecting surface must have a neutral colour or be white. Off camera direct flash mitigates some of the unfavorable qualities of direct, on camera flash, but direct light from a small source, on or off the camera, is still harsh. It cannot be used to illuminate a scene evenly with substantial from-to-back depth, and it never looks like natural light – it always looks like flash. For every difficulty, there is usually a solution. If the flash is aimed not at the subject but a large surface such as a wall, ceiling, or cardboard reflector, that large surface now becomes the source. The scene is then bathed with soft, broad illumination that falls on subjects from many directions. And because it comes from the side or top, and not directly from the front, shapes and textures are nicely defined. Furthermore, light bounced off a ceiling simulates the indoor overhead illumination with which we are so familiar. Similarly, light bounced off a wall falls on the subject in the same beautiful manner as soft, indirect light from a window. Bounce flash photography looks believable. The Bounce Surface Select a bounce surface appropriate for the subject. If the flash is too close to the reflector, the light will not have sufficient distance to spread out and become a large source. Conversely, if too far, the light may spread out more than the subject requires, wasting illumination. Ceilings are traditional bounce surfaces, but don’t hesitate to use walls, a shade or binds pulled down over a window, or even a cardboard reflector. In all cases, the bounce surface must be light in tone, and proper colour rendition, the surface should be white, slightly off-white, or gray. Unusual colour results from bouncing off a coloured surface. Aiming the Flash The flash head must be angled so that light reflected from the bounce surface will fall where you want it, this is best accomplished by aiming the flash head at a point midway between flash and subject. Unsuccessful bounce flash pictures can often be traced to careless aiming – the light falls in front of or behind the subject. Particularly with the flash mounted on the camera, it is easy to change the aim point of the flash head accidentally as the camera is moved for a desired composition. Make sure also that direct flash doesn’t accidentally spill onto the subject. Flash Operating Considerations The desirable qualities of bounce flash are obtained at the cost of: 1. Significantly limited range when compared with direct flash. 2. The need to use relatively large apertures, thereby limiting depth of field. 3. Somewhat more complicated exposure considerations. Bouncing the light weakens its intensity on the subject. The bounced surface, even if white, absorbs some light energy, and more significantly, scatters the light in directions other than toward the subject. This diminished brightness dictates larger apertures. And whatever the flash unit’s range for direct flash, it will be greatly diminished when used for bounced. This is one case where highpower flash equipment and/or fast film can be extremely helpful. Bounce Flash Exposure Bounce flashes in the automatic mode 1. Make sure that the sensor is directed towards the subject. 2. Check for correct aperture setting by firing trial flashes. 3. Change aperture if required. 4. Watch the auto check indicator. 5. The auto working ranges do not apply here. 93 Manual bounce flashing 1. Select manual mode. (In this mode the aperture setting required for taking shots in small rooms is: f-number on camera lens = Guide number 2 X flash-to-subject distance. Bouncing Flash Into Umbrellas Flash bounced from walls, ceilings, and other flat reflectors is extremely effective for room-size situations, and even portraits and still lives. However, these bounce surfaces leave much to be desired in the way of directional control. They also waste considerable light energy, and they may have an undesirable colour. What’s more, light coloured walls and ceilings frequently either do not exist at all or are too far from the subject to be of much use. A photographic umbrella, used to reflect light from a flash, provides the soft luminosity of a large light source. Umbrella illumination has good directional control, proper colour characteristics, and wastes far less light than a reflector. An umbrella, stand, and flash also make a reasonable portable package with sophisticated capabilities. Exposure with Umbrellas Because the flash is mounted completely away from the camera, automatic exposure operation is only possible if the flash unit has a remote sensor or if you are using a TTL flash system. In manual mode, the modified guide number system can be used. Of course the flash-to-subject distance is the sum of the umbrella-to-subject distances. Electronic Flash Prac.

This task is ongoing throughout the year. It is an essential part of recording, analysing and documenting information which is relevant to developing work for the folio. The entries in the visual diary should include students: • written observations which reflect the thinking,planning and experimental stage of their folio. • images collected from magazines,newspapers, digital images contact prints and photocopies which provide inspiration for development their work. • drawings,sketches, illustrations and plans relating to future photographic shoots or digital image making. • documentation relating to different photographic techniques, materials and processes. • research notes into artists(past and present) who inspire and motivate them. • poetry, lyrics and other personal expressive writing. Folio Review Method Regular reviews will be held at the end of each term or as determined by the group, and it is expected that all students attend. Students should bring a minimum of three new prints. Concepts that are still being worked through are acceptable, however these concepts need to be articulated. The Folio Review provides a forum to offer positive criticism and appreciation. The value of folio review relies on participation. During the review, identify the various fields of photography and discuss how your own and others images may fit into these fields. Evaluate images in the light of impact and suitability to purpose.

There are a number of ways to do this. One method was demonstrated in class last week. This is another way, as well as a ‘follow on’ of technique from the multiple self-portrait assignment. Select the quick select tool in Photoshop CS5. Click and drag over the area you wish to create a mask. Make sure your mask panel is visible (Window- Masks). Click on the layer mask icon and a layer mask will appear, much in the same way as you created the layer masks for your multiple self-portrait assignment. Click on Mask Edge in the dialog box and another panel will appear. You can now make adjustments to fine tune your selection that will alter and refine your layer mask. You can also select different viewing options as you refine your layer mask. In this example Black & White is used (K) so the mask can be clearly seen. After adjustments are made change to On Layers (L) As you can see, the mask created by the Quick Select Tool is quite rough. The first stage of creating more accurate mask is by checking the Smart Radius box and adjusting the radius. In this example I have increased the radius to approximately 89 so as to include the fine outline of hair and the texture of fabric. You can then switch viewing option to On Layer (L) to se the accuracy of the mask. Using the sliders you can adjust the mask edges ie. Smooth, Feather, Contrast and Shift Edge Digital Zone Ruler & Levels Open up you digital zone ruler PSD file. You will be looking at a selected photograph from your archives and analysing different parts of the image in terms of the digital values, ink percentage values and the zone system values. Open up an image which has even tonal distribution. ie. One that is not “high key” or “low key; one that has shadows, highlights and mid-tones. For this exercise, select a JPEG file. (The image will be an RGB, 8 bit file.) When you open your image, select the workspace, ANALYSIS from the top right corner. (It may be on the default “Essentials” setting). You will notice that three panels will appear; The Histogram Panel, Info Panel and Channels/Layers Panel. (A “measurement log” panel will appear at the The Histogram Panel The Histogram Panel offers many options for viewing tonal and colour information in an image. The Histogram is a graph which shows the distribution of colour & tone in your image. Each pixel in an image is comprised of some combination of Red, Green & Blue. Each of these colours can have a brightness value ranging from 0 to 255 in an 8-bit digital image. We refer to this as 256 levels of tone. A RGB Histogram is a graph of how many RGB brightness values are at each level from 0 to 255. This corresponds with the DIGITAL VALUES on your ZONE RULER. Ensure that you have selected RGB in your Histogram channel to see this. THEN, select the alternative channel options to see the distribution of individual colours and luminosity. INFO Panel The Info Panel can be used to determine measurements of certain elements in your image, such as colour, density and size. In this exercise you will be looking at the different VALUES in your image that correlate to the ZONE RULER. (Digital values and Percentage Ink Values) Subsequently you will be able to see where specific areas fall into certain ZONES. 103 In your INFO panel, select Panel Options from the top right icon. For your first analysis of your image, select “Grayscale” for the first colour readout and “HSB colour” for the second. This is an acronym for Hue Saturation and Brightness. K stands for black (as B stands for Blue) Look at your Digital Zone Ruler. What value does the K measure? What value does the B measure? Look at the demo image on the projection screen. What ZONES are being selected in the image? Move the cursor over different areas of your image to determine the different zones. Make sure you repeat this process with a number of different images; low key and high key images etc. Get into the habit of analysing your photographs based on the histogram and the information present. Now bring up an image that is High Key and Low Key. Analyse the results in the histogram panel and the information panel. The general rule in photography (be it analogue or digital) is to create an image which falls in between Zone 2 and Zone 9. Why is this so? 104 HOWEVER. Rules are made to be broken. This is just a general rule for achieving a photograph with even tonal variation. You may wish to capture an low-key image which has a large sections that is Pure Black (Zone 0), for example. 105 Levels & The Histogram In your Photoshop workflow, the first adjustment you will make to your image will be the Levels. The Levels adjustment is used to control/alter the tonal range and colour balance of your image. The Levels adjustment feature allows us to ensure that the image is using the full tonal range between white and black. It shows the levels of exposure (LIGHT) present in your image. This directly relates to your zone ruler. Before we begin to adjust the levels of an image, duplicate the locked, background layer. Right-click on layer > Duplicate layer Go to menu > Layer > Duplicate layer OR Click and drag layer into Create a New Layer icon at bottom of layers panel. NOTE! The peaks and valleys represent the number of pixels at that brightness value. You will now apply a Levels adjustment layer to your image. Using adjustment layers allows for non-destructive editing. There are a number ways you could do this. (See demo in class). This way you are not changing/manipulating the actual pixels of the image. As you can see the adjustments are made on a separate floating layer. The adjustments made on this layer effect the image below it. Look at the distribution of Tones on your histograms. What Zones do most of the areas fall under? 106 The Levels Dialog in Detail Select Custom for more accurate adjustments Automatic Adjustment for colour, contrast and Levels The eye dropper tools can be used as an alternative to the Input sliders. Shadow Slider Mid-tone Slider Highlight Slider This calculates a more accurate histogram Return to adjustment list Delete adjustment Layer Switches panel to expanded view This adjustment effects all layers below Reset to adjustment defaults Press and hold to view previous state Toggle layer visibility 107 The dialog box with a Histogram gives us an indication of how many pixels appear at each level of Brightness in the image. Level 0 on the left is absolute black and Level 255 on the right is absolute white. Therefore there are 256 levels of brightness in each of the channels. As you can see, a zone ruler of sorts appears below the histogram in the dialog box. Look at your Zone Ruler to see the relationship. Below the histogram are three sliders: black, grey and white. These are called Input Shadow Slider, Gamma Slider and Input Highlight Slider, respectively. With levels, the goal is to change contrast without losing detail in the Shadows or Highlights. When this loss of detail occurs (in the highlights or shadows), it is called “Clipping”. You are essentially removing non-digital values Starting with the Input Highlight Slider. Hold down the alt/Option key and click your cursor on the white slider. Your image will go black. (This is called Threshold view.) From the demonstration image, you will see that the clipping begins to appear at the digital value of 211. (This is in between Zone 8 and Zone 9 on the Zone ruler.) Now do the same with the Input Shadow Slider. You will notice that your screen will go white. In the image pictured you will notice that there is a small amount of clipping already. It is therefore not necessary to move the black slider in this example. This indicates that the image was slightly underexposed when shot. Youtube Videa Link to adjusting levels It is important that you take note of the histogram inside your digital camera after each exposure to ensure that you are achieving correct exposures. 108 You will notice that as a result of adjusting the Levels, your histogram will change and will sometimes appear with broken lines. This is called the “combing effect”. It signifies a loss of information in the image. This is because the tones/colours have been remapped/ re-distributed so as to spread across the histogram. You will notice that this combing is only affecting the adjustment layer. You can also target individual colour channels when using the Levels adjustment. 109 Creating a Zone Ruler Using Photoshop create and print a zone ruler to determine the accuracy and quality of the Epson Desktop Inkjet Printers. Assignment. Print one copy in Black and white mode and one copy in colour mode for your tech journal. Compare the two prints. Write up your conclusions on the quality of the output versus the screen rendering of the image, as well as differences between the two prints. Follow these instructions, 1. 2. 3. 4. 5.

Once you have found your location, set your tripod up with your camera and make sure that you have your camera set at 200 ISO, with the appropriate shutter speed and aperture depending on the light. 3. Take 4 self portrait shots in different positions without moving the camera. 4. Once you have taken the appropriate shots, take them back to the Digital room and begin downloading your Images. TTL function with your camera. Remember to name all your layers The eye icon, turns the visibility of the layer on and off. 112 In Photoshop there are Layer Masks and Masks which allow you to use the layer mask as a method of concealing and revealing certain sections of your image. This also can be directly used when making selections and then further refining the selections using the brush tool. 8. Using the lasso tool, make a selection around one of the self portraits that you want to include in you multiple self portrait. 9. Once your selection is active go to layer>layer mask, you then are presented with 4 options; Reveal All, Hide All, Reveal Selection & Hide Selection. Reveal All & Hide All are associated to creating layer masks over whole image layers Reveal Selection & Hide Selection are associated to creating layer masks when there is an active selection. 10. Make your selection and then go to Layer>Layer Mask> Reveal Selection. Make sure that when you are working on the layer mask it is selected. Layer Mask. Black is concealing the image, and white is the area of the image that is being revealed. Use the brush tool with your foreground and and background colours set to black and white (hit D to return them to their defaults) and then follow the rule of black to conceal and white to reveal and adjust your selection using the layer mask. 113 Processing a Raw file Process a RAW file using Adobe Camera Raw after making minor global adjustments. Save as a TIFF file to a desired folder, then open in Photoshop. Alternatively, open in Photoshop straight away and proceed with making the following adjustments; Localised Curve Adjustment Layers Load a Levels adjustment layer. Ensure there is no further highlight or shadow clipping. Make further adjustments if need be. Load a CURVES adjustment layer. Using the on screen adjustment tool, isolate a specific area you wish make localised tonal adjustments (ie. skin tones, sky etc). Modify the curve slightly to darken/lighten chosen area. THEN click on the accompanying layer mask. Invert layer mask (Command I). Press D on your keyboard to ensure the colour picker is on the default setting of black & white. (Ensure that white is your foreground colour). Use the brush (B) to ‘reveal’ the areas you wish to apply this curve adjustment to. neutral grey layer will appear. You will see no change to your image. Select black from your colour picker. Select the Brush tool (or hit B on your keyboard). In the Tool Options bar, select a low brush opacity, ie 12%. Brush over the areas you wish to darken in exposure. You may wish to repeat this process to dodge certain areas (decrease/hold back in exposure). NOTE. You may wish to turn off the visibility of your Curves group folder and note differences. Sharpening your Image You now have a number of adjustment layers in your layers panel. You will now be creating a single layer which will comprise of all the adjustments you made so far. This will then be used to apply a sharpening layer to your image. Ensure the top layer is selected (highlighted in blue). From the drop NOTE. a low opacity brush is desirable. Change the brush size according to the area you are painting away to reveal your adjustment. (On your keyboard, use square bracket keys as a shortcut). Repeat this process to one or more other areas. Grouping layers Create a layer ‘group’ folder. (Command G) then drop and drag curve adjustment layers into said folder. Name your folder “curves” or “curve adjustments”. Burning & Dodging Just as you burn and dodge areas of a print in the darkroom, you can also apply a similar technique in Photoshop. As an alternative to using the burning and dodging tool from the Tools panel/ palette, you can use this method for more accurate exposure adjustments. Hold down the alt/option key and click on the “Create a New Layer” icon at the bottom of your Layers panel. A New Layer dialog box will appear. Name your layer “Burn”. (You will be creating an additional ‘dodge’ layer separately.) The Colour Selection should read “None”, for Mode, scroll down to select “Soft Light” and check “Fill with Soft-Lightneutral color (50% gray)”. (See below) A down menu in your layers panel, select Merge Visible, however as you do this, hold done the Alt/Option key. Continue to hold down after your mouse is released. If you release the Alt/Option key too soon, all layers will merge, however adjustment layers will be lost. The image will in effect, be flattened. A new layer comprising of all layers below it will be created. Duplicate this layer. Name it “High Pass” or “Sharpen”. From the Filter drop down menu, select Other - High Pass. A dialog box will appear containing a preview window. This is automatically set at 100%. Decrease the size to properly view your image. Move the slider to select a small radius in pixels. (ie. 6.0%) It is a good idea to make subtle changes to the sharpness of your image. Click OK. You will now need to change the Layer Blending mode in order to see the resulting effect. In the Drop Down menu in your Layers panel, select Overlay and observe the changes. Do the same with Soft Light and Hard Light. Experiment with Altering the Layer Opacity to lessen the intensity of your sharpening adjustment. (Zoom in to better see the effect of the sharpening) Localised Sharpening As with the demonstration of localised curve adjustments, you should also apply a Layer Mask to isolate specific areas you wish to sharpen. Click on the layer mask icon in your Layers panel. Invert the Layer (Command I), select white from the colour picker (press D to default back to black & white if other colours are present) and use the brush tool to reveal the areas you wish to sharpen. Once again, select a low brush opacity to gradually reveal the sharpened areas. Once again, further adjust the Layer Opacity to the desired level. Turn the layer visibility off to see the extent of the adjustment and assess it’s effectiveness in relation to your image. Remember, don’t go overboard with any of these adjustments. Subtlety is the key!! NOTE! This is merely an exercise in the exploration of different techniques. Do not feel that you have to make numerous adjustments to your image every time. It may be a matter of only adjusting the levels and curves, then your image is ready for output. You will now need to change the Layer Blending mode in order to see the resulting effect. In the Drop Down menu in your Layers panel, select Overlay and observe the changes. Do the same with Soft Light and Hard Light. Experiment with Altering the Layer Opacity to lessen the intensity of your sharpening adjustment. (Zoom in to better see the effect of the sharpening) Spot Healing Tool Cleaning up scanned negatives,using a variety of tools. These tools are the Spot Healing Tool, The cloning tool. Healing Tool In addition to the spot healing tool, the Healing Brush Tool can be used to in a similar way to the clone tool. Areas of various sizes can be ‘sampled’ and applied to another desired area. Hold down the alt/Option key when clicking the mouse/cursor on the desired sample area (Source point). Where ever you move the cursor a ‘preview’ of the sample can be seen. Then, click on the point where you want the area to be cloned. Clone Tool You may still wish to use the old faithful Clone Tool. It works in a very similar way to the Healing Brush Tool. The source area is sampled by pressing alt/Option and then cloned to another destination. Unlike the Healing Tool, the Clone Tool basically copy/pastes the pixels from the source point. It does not try to match the surrounding pixels in terms of tonality/texture. Deactivate the visibility of the top layer and you will see where you have made the corrections. Working in this non-destructive way allows you to easily fix mistakes. The ‘spots’ can be easily removed using the eraser tool or lasso selection tool and hitting Delete. Create a new SEPARATE, non destructive layer. Name the layer, “Small Dust Marks” or another appropriate title. Ensure you have selected Sample All Layers in the top Options menu bar. Spot Healing Brush Tool Using the Spot Healing Brush Tool you may want to clean up a few small dust marks. Choose a brush size just marginally bigger than the dust mark (left and right bracket keys are the short cut to do so) and choose a low opacity (‘soft”) brush size. Simply click over the dust marks to watch them disappear. Deactivate the visibility of the top layer and you will see where you have made the corrections. Working in this non-destructive way allows you to easily fix mistakes. The ‘spots’ can be easily removed using Remove Spots with Eraser Tool the eraser tool or lasso selection tool and hitting Delete. Remove Spots with lasso selection and delete key 115 Photographic History A Glossary of Alternative Silver Processes. Albumen Print Albumen printing paper was invented by a Frenchman, Louis Blanquart- sensitised the paper by brushing over a solution of silver nitrate and gallic acid. He placed it in the camera for thiosulphate (hypo). Because there was there was no negative , each daguerreotype was a one-of- a-kind Evard, around 1850. By 1855 it had become the major photographic printing technique, and it remained dominant until the 1890’s. The paper was prepared commercially by coating exposure, then developed it by again brushing on the silver/gallic acid solution. He fixed it in sodium thiosulphate (hypo). To make this fairly dense paper negative more image and, like the image in a mirror reversed. large sheets with a solution of egg albumen and ammonium or sodium chloride. It was dried, cut into smaller sheets, and sold in this form. Photographers sensitised it transparent, Talbot applied a coating of wax. He made prints from the negative using the salted paper process he invented in 1834. Because of the texture of the paper, printing papers containing light sensitive silver chloride or silver bromide in a gelatine emulsion. Papers of this type first became available in the 1870’s and are still in themselves by floating the paper, albumen-side-down in a tray containing silver nitrate solution, The silver nitrate combined with the chloride in the albumen coating to prints from calotype negatives did not have the minute detail possible with the daguerreotype, the rival process at the time. But the calotype had a great advantage over the daguerreotype in use. Before their introduction, most photographic printing was done on albumen papers. The various gelatine silver papers were superior to albumen in that they came ready to provide silver chloride, which darkens on exposure to light. After drying the paper, the photographer printed it by contact beneath a negative, exposing it to that any number of prints could be made. The calotype was supplanted in the early 1850’s by the wet plate negative. Since it used a glass support instead of paper, the wet plate use (photographers first had to sensitise albumen paper themselves before printing), were far more sensitive to light, and were available in different contrast grades to suit sunlight. The image appeared during exposure - no development was necessary. It was then toned in a solution of gold chloride and fixed in sodium thiosulphate (hypo). could better retain image detail. different negatives. They made printing and enlarging with artificial light practical. Albumen papers largely replaced plain salted papers, although the latter process remained in limited use because it was inexpensive and could be simply prepared at home or in a process came in January 1839. It was the first time the public learned of photography. Daguerre had begun his experiments around 1826, and four years later formed a partnership with Also known as Gum Bichromate Alphonse Louis Poitevin patented the first gum printing process in 1855. It was based on a discovery made in 1839 that paper coated with studio. Albumen had the advantage of a gloss surface, which could preserve image detail better than the matt surface of salted paper and also made the blacks appear deeper. Joseph Niepce, another early experimenter. Following up on one of Niepce’s dicoveries,Daguerre found that an iodised silver plate, experimenter. Following up on one of potassium dichromate (then called bichromate) darkens on exposure to light. About 1852, William Henry Fox Talbot, the inventor of the calotype process, had found that when a water- Calotype Invented by William Henry Fox Talbot in 1840, the calotype was the first practical method for making Niepce’s discoveries, Daguerre found that an iodised silver plate, exposed to light, would produce an image if developed with the mercury fumes. The daguerreotype process involved soluble colliod such as gum arabic or gelatine was mixed with potassium dichromate and exposed to light, the colloid became hard and insoluble in all except very hot water. Building on photographic negatives based on the principle that certain salts of silver are sensitive to light and dark when exposed. Talbot first brushed a solution of silver nitrate over a sheet of first sensitising a silver coated copper plate by placing it in a box filled with iodine vapour. This created lightsensitive silver iodide. After exposure in a camera, the plate was in another this, Poitevin coated paper with a solution of gum arabic, finely ground pigment, and dichromate, and exposed it to sunlight beneath a negative. In the shadow areas of the paper, then dipped the paper in potassium iodide. It could be stored in this form until needed. Talbot box containing mercury, which was then toned in a solution of gold chloride and fixed in sodium colloids became completely insoluble, but remained soluble in the highlights and partly soluble in the middle tones. Daguerreotype The announcement of Louis Jacques Mande Daguerre’s revolutionary Gelatine silver A general term for photographic Gum print or Gum Bichromate 118 He then developed it in a tray of water. The soluble gum dissolved in the water, carrying the pigment with it. In paper with common salt (sodium chloride), then brushed it over with a solution of silver nitrate. The two using gold chloride, before the fixing bath. Albumen image was toned using gold chloride, before the fixing bath. the exposed parts the pigment remained on the paper, forming the image. One disadvantage of the process was that the image was less sharp and the chemicals combined to form silver chloride, a substance that darkens spontaneously on exposure to light. The photosensitivity of silver chloride had been known before Talbot’s time Albumen paper began to replace salted pictorialist photographs in the 1890’s. tonal scale less accurate than was possible on the then popular albumen paper. One important advantage was that pigments could be chosen that were for more permanent than the and others had experiments along the same lines, but Talbot discovered that its sensitivity could be greatly increased if prepared using an excess amount of silver nitrate, so that some Invented by Frederick Scott Archer in 1851, the wet-plate, or collodion process, was the most popular method of negative making until the introduction of the gelatine dry plate in solver in an albumen print. The gum process was largely forgotten until the 1890’s when it was revived by pictorial photographers who found it especially useful for creating effects resembling silver nitrate was left over after the reaction forming silver chloride. He also discovered that he could fix the exposed image, so that it could be viewed in the light without continuing the 1880’s. The photographer first coated a sheet of glass with collodion mixed with potassium iodide. The collodion formed a clear film. Next, he sensitised the plate by dipping it in a those in impressionist paintings. One of their methods was to develop the image locally with a brush or a stream of water to modify the tones or eliminate unwanted details. It was to darken, by washing it in a solution of common salt, thus reversing the nitrate/chloride balance. This crucial fixing method had eluded the earlier experimenters. Even so, Talbot did bath of silver nitrate, placed it in the camera for exposure, and afterwards developed the image in ferrous sulphate and fixed it in sodium thiosulphate ( hypo). The process got also possible to re-coat the dry image with a gum solution of the same or a different colour and print it again in registration under the negative. This deepened the tonal scale, adding rich not reveal his discoveries until January 1839, prompted only by the announcement of the daguerreotype. its name from the fact that all of this had to be done while the collodian remained moist; otherwise the plate lost it’s sensitivity. Collodian negatives were usually printed on Albument shadows and also allowed colour effects to be introduced into the image. paper. Salt print 1840’s through the 1860’s as a printing paper for both calotypes and wetplate negatives. It was sensitised by the photographer, printed by contact in sunlight until the image had fully Invented by William Henry Fox Talbot in 1834, this was the first truly successful photographic printing method. Talbot coated a sheet of appeared, then fixed in sodium thiosulphate (hypo) - which had been found to do a better fixing job than salt. Sometimes the image was toned and Hudson, s1983 Salt paper was popular from the Wet Plate or Collodion Process ref: “Photography as Fine Art” by Douglas Davis, Published by Thames 119 The Early Beginnings of Photography First, the name. We owe the name "Photography" to Sir John Herschel, who first used the term in 1839*, the year the photographic process became public. The word is derived from the Greek words for light and writing. Angelo Sala, in the early seventeenth century, noticed that powdered nitrate of silver is blackened by the sun. Before mentioning the stages that led to the development of photography, there is one amazing, quite uncanny prediction made by a man called de la Roche (1729- 1774) in a work called Giphantie. In this imaginary tale, it was possible to capture images from nature, on a canvas which had been coated with a sticky substance. This surface, so the tale goes, would not only provide a mirror image on the sticky canvas, but would remain on it. After it had been dried in the dark the image would remain permanent. The author would not have known how prophetic this tale would be, only a few decades after his death. At the beginning of the nineteenth century Thomas Wedgwood was conducting experiments; he had successfully captured images, but his silhouettes could not survive, as there was no known method of making the image permanent. There are two distinct scientific processes that combine to make photography possible. It is somewhat surprising that photography was not invented earlier than the 1830s, because these processes had been known for quite some time. It was not until the two distinct scientific processes had been put together that photography came into being. The first of these processes was optical. The Camera Obscura (dark room) had been in existence for at least four hundred years. There is a drawing, dated 1519, of a Camera Obscura by Leonardo da Vinci; about this same period its use as an aid to drawing was being advocated. The second process was chemical. For hundreds of years before photography was invented, people had been aware, for example, that some colours are bleached in the sun, but they had made little distinction between heat, air and light. In the sixteen hundreds Robert Boyle, a founder of the Royal Society, had reported that silver chloride turned dark under exposure, but he appeared to believe that it was caused by exposure to the air, rather than to light. In 1727 Johann Heinrich Schulze discovered that certain liquids change colour when exposed to light. The first successful picture was produced in June/July 1827 by Niépce, using material that hardened on exposure to light. This picture required an exposure of eight hours. On 4 January 1829 Niépce agreed to go into partnership with Louis Daguerre . Niépce died only four years later, but Daguerre continued to experiment. Soon he had discovered a way of developing photographic plates, a process which greatly reduced the exposure time from eight hours down to half an hour. He also discovered that an image could be made permanent by immersing it in salt. Following a report on this invention by Paul Delaroche , a leading scholar of the day, the French government bought the rights to it in July 1839. Details of the process were made public on 19 August 1839, and Daguerre named it the Daguerreotype. The announcement that the Daguerreotype "requires no knowledge of drawing...." and that "anyone may succeed.... and perform as well as the author of the invention" was greeted with enormous interest, and "Daguerreomania" became a craze overnight. An interesting account of these days is given by a writer called Gaudin , who was present the day that the announcement was made. However, not all people welcomed this exciting invention; some pundits viewed in quite sinister terms. A newspaper report in the Leipzig City Advertiser stated: "The wish to capture evanescent reflections is not only impossible... but the mere desire alone, the will to do so, is blasphemy. God created man in His own image, and no man- made machine may fix the image of God. Is it possible that God should have abandoned His eternal principles, and allowed a Frenchman... to give to the world an invention of the Devil?" At that time some artists saw in photography a threat to their livelihood, and some even prophesied that painting would cease to exist. The Daguerreotype process, though good, was expensive, and each picture was a once-only affair. That, to many, would not have been regarded as a disadvantage; it meant that the owner of the portrait could be certain that he had a piece of art that could not be duplicated. If however two copies were required, the only way of coping with this was to use two cameras side by side. There was, therefore, a growing need for a means of copying pictures which daguerreotypes could never satisfy. Different, and in a sense a rival to the Daguerreotype, was the Calotype invented by William Henry Fox Talbot , which was to provide the answer to that problem. His paper to the Royal Society of London, dated 31 January 1839, actually precedes the paper by Daguerre; it was entitled "Some account of the Art of Photogenic drawing, or the process by which natural objects may be made to delineate themselves without the aid of the artist's pencil." He wrote: "How charming it would be if it were possible to cause these natural images to imprint themselves durably and remain fixed on the paper!" The earliest paper negative we know of was produced in August 1835; it depicts the now famous window at Lacock Abbey, his home. The negative is small (1" square), and poor in quality, compared with the striking images produced by the Daguerreotype process. By 1840, however, Talbot had made some significant improvements, and by 1844 he was able to bring out a photographically illustrated book entitled "The Pencil of nature." Compared with Daguerreotypes the quality of the early Calotypes was somewhat inferior. (See comments on Claudet). However, the great advantage of Talbot's method was that an unlimited number of positive prints could be made (see also Brewster ). In fact, today's photography is based on the same principle, whereas by comparison the Daguerreotype, for all its quality, was a blind alley. The mushrooming of photographic establishments reflects photography's growing popularity; from a mere handful in the mid 1840s the number had grown to 66 in 1855, and to 147 two years later. In London, a favourite venue was Regent Street where, in the peak in the mid 'sixties there were no less than forty-two photographic establishments! In America the growth was just as dramatic: in 1850 there were 77 photographic galleries in New York alone. The demand for photographs was such that Charles Baudelaire (1826-1867), a well known poet of the period and a critic of the medium, commented: "our squalid society has rushed, Narcissus to a man, to gloat at its trivial image on a scrap of metal." Talbot's photography was on paper, and inevitably the imperfections of the paper were printed alongside with the image, when a positive was made. Several experimented with glass as a basis for negatives, but the problem was to make the silver solution stick to the shiny surface of the glass. In 1848 a cousin of Nicephore Niépce, Abel Niépce de Saint-Victor, perfected a process of coating a glass plate with white of egg sensitised with potassium iodide, and washed with an acid solution of silver nitrate. This new ( albumen ) process made for very fine detail and much higher quality. However, it was very slow, hence the fact that photographs produced on this substance were architecture and landscapes; portraiture was simply not possible. Progress in this new art was slow in England, compared with other countries. Both Daguerre and Fox Talbot were partly responsible, the former for having rather slyly placed a patent on his invention whilst the French government had made it freely available to the world, the latter for his law-suits in connection with his patents. In 1851 a new era in photography was introduced by Frederick Scott Archer , who introduced the Collodion process. This process was much faster than conventional methods, reducing exposure times to two or three seconds, thus opening up new horizons in photography. Prices for daguerreotypes varied, but in general would cost about a guinea (£1.05), which would be the weekly wage for many workers. The collodion process, however, was much cheaper; prints could be made for as little as one shilling (5p). A further impetus was given to photography for the masses by the introduction of carte-de-visite photographs by Andre Disdéri . This developed into a mania, though it was relatively short-lived. The collodion process required that the coating, exposure and development of the image should be done whilst the plate was still wet. Another process developed by Archer was named the Ambrotype , which was a direct positive. The wet collodion process, though in its time a great step forward, required a considerable amount of equipment on location. There were various attempts to preserve exposed plates in wet collodion, for development at a more convenient time and place, but these preservatives lessened the sensitivity of the material. It was clear, then, that a dry method was required. It is likely that the difficulties of the process hastened the search for instantaneous photography. Skaife, in a pamphlet, aptly commented (1860): "Speaking in general, instantaneous photography is as elastic a term as the expression 'long and short.'" The next major step forward came in 1871, when Dr. Richard Maddox discovered a way of using Gelatin (which had been discovered only a few years before) instead of glass as a basis for the photographic plate. This led to the development of the dry plate process. Dry plates could be developed much more quickly than with any previous technique. Initially it was very insensitive compared with existing processes, but it was refined to the extent that the idea of factorymade photographic material was now becoming possible. The introduction of the dry-plate process marked a turning point. No longer did one need the cumbersome wet-plates, no longer was a darkroom tent needed. One was very near the day that pictures could be taken without the photographer needing any specialised knowledge. Celluloid had been invented in the early eighteen-sixties, and John Carbutt persuaded a manufacturer to produce very thin celluloid as a backing for sensitive material. George Eastman is particularly remembered for introducing flexible film in 1884. Four years later he introduced the box camera, and photography could now reach a much greater number of people. Other names of significance include Herman Vogel , who developed a means whereby film could become sensitive to green light, and Eadweard Muybridge who paved the way for motion picture photography. Popular in the Victorian times was stereoscopic photography , which reproduced images in three dimensions. It is a process whose popularity waxed and waned - as it does now - reaching its heights in the mid-Victorian era. 1) Well, actually, not quite. Whilst Herschel used the term first in a lecture before the Royal Society on March 14, 1839, he was in fact beaten to the post by an anonymous writer with the initials "J.M." a few weeks earlier, on February 25. Eventually a scholar was able to determine that this anonymous writer was in fact Johann von Maedler (1794-1874), who was an astronomer in Berlin. However, Hershel was undoubtedly the person who, with his fame and position, made the word "photography" known to the world. This text has been lifted in its entirety from the former website of Robert Leggat, b 1941 - d 2011 2) Significant Figures and Processes from the Beginnings of Photography to the 1920’s The "291" Gallery A growing dissatisfaction with the photographic establishment in England and in America at the turn of the century led to the formation of new groups such as the Linked Ring in the UK, and a group of avantegarde photographers in the United States, spearhearded by Stieglitz The American group came to be known as the Photo-Secession. From November 1905 this group laid on exhibitions of work at "The Little Galleries of the Photo-Secession" at 291 Fifth Avenue, New York, which came to be known simply as "291." Though the idea initially had been to display the new form of photography, the 291 evolved to become a major focal point of modern art. Paintings exhibited included those of Cezanne, Rodin, Matisse, Picasso, and Toulouse-Lautrec. In 1917 the 291, in financial difficulties, closed its doors, though Stieglitz operated other similar galleries up to the 1940s. The ADDITIVE colour process There are two different ways of producing a colour, the additive and the subtractive. In the additive process, all colours can be made by mixing three primary colours: red, green and blue. Yellow, for example, is a mixture of green and red light. This process was first demonstrated, in 1861, by Sir James Clerk Maxwell. Though this was the first of the two, it was the subtractive process which was to become the standard colour one in our lifetime. had been thought of - even the slime left by snails - nothing proved reliable. In 1848 a cousin of Nicephore Niépce, Abel Niépce, perfected a process which consisted of coating a glass plate with salted white of egg containing some potassium iodide. The plate was then left to dry, after which it was sensitised with an acid solution of silver nitrate. After exposure it was then developed in gallic acid. ALBUMEN process In the late 1840s albumen came to be used in the preparation of both negatives and printing paper, in order to increase the definition. This new process made for very fine detail and much higher quality. However, it was very slow, with exposure times ranging between five and fifteen minutes, so it was used for architectural or still life work, not for portraiture. The first development was at the negative stage. Talbot's negatives were on paper, and inevitably, when a positive was made, the imperfections of the paper were printed along with the image. The answer would be to use glass negatives rather than paper, but the chemicals would not adhere to the glass without a suitable binder. Though several substances The development of albumen printing paper, two years later, met with much greater success; this was introduced in France by Blanquart-Evrard, brought to this country by John Mayall and made known in England by Hugh Welch Diamond. (One source, however, suggests that this process was first described at the Photographic Society by Henry 122 Pollock.) Until then, salted paper, with its limitations of definition, had been used. An article by Shadbolt in The Journal of the Photographic Society (1855) states the problem: "The more the picture is kept upon the surface of the paper, the more brilliant is the effect, and the more perfectly is the detail, especially that of the half tones brought out, and that anything like soaking the solutions into the paper produces a flat and unsatisfying effect." Here the chemicals would be on the paper rather than in it, as in the case of the salted-paper process. It was a glossy printing paper which produced a very smooth surface and therefore permitted reproduction in much greater detail. However, initially the albumen process was not seen as the ideal answer. Shadbolt, for example, continued: "the offensive and vulgar glare which it possesses sometimes is more detrimental to pictorial effect than is counter- balanced by other advantages, and I see no reason why all the delicacy of albumenized proofs should not be retained by adopting other means to this end, and yet be free from so unpleasant a defect as the glare alluded to..." whilst Sutton wrote: "As a matter of taste, I extremely dislike prints on albumenized paper, and they consequently never find a place in my portfolio...", and evidently had little time for "those who prefer that peculiar kind of vigour and brilliancy which is exhibited by a piece of black sticking plaster, or a well-polished Wellington boot..." To reduce the glaze, some diluted the albumen. Nevertheless the process began to catch on, and by the sixties it was in general use, and continued to be so until the turn of the century. Its success may be judged by the fact that one of the photographic journals printed recipes for using the egg yolks left over after the whites had been used for photographic purposes. It was said that one supplier of albumen paper alone was using sixty thousands eggs a day! Albumen printing paper continued to be in general use until the turn of the century, when gelatine paper began to replace it. AMBROTYPE process If a very thin under-exposed negative is placed in front of a dark background, the image appears like a positive. This is because the silver reflects some light whilst the areas with no silver at all will appear black. This is the principle behind the Ambrotype process, the pictures being more correctly known as Collodion positives. Ambrotypes were made from the 1850s and up to the late eighties, the process having been invented by Frederick Scott Archer in collaboration with Peter Fry, a colleague. Ambrotypes were direct positives, made by under-exposing collodion on glass negative, bleaching it, and then placing a black background - usually black velvet, occasionally varnish behind it. Though Ambrotypes slightly resemble Daguerreotypes, the method of production was very different, and Ambrotypes were much cheaper. The Ambrotype process was yet another method of reducing the cost of photography. It became popular for a number of reasons: •less exposure time was needed •production was cheaper and quicker, as no printing was required •as the negative could be mounted the other way, by placing the collodion side on top of the backing material, there was no lateral reversal, as there was in most Daguerreotypes. •unlike Daguerreotypes, they could be viewed from any angle Ambrotypes became very popular, particularly in America. The process is also called "Melainotype" in the European continent. Another variant of this was the Tintype process. ARTISTS and Photography The invention of the Daguerreotype caused considerable concern to many artists, who saw their means of livelihood coming to an end. Delaroche is credited with claiming that painting was now dead, whilst it is said that Sir William Ross, on his death-bed in 1860, commented sadly that "it was all up with future miniature painting." It is also claimed, but with scanty evidence, that Turner, looking at an early daguerreotype, commented that he was glad he had had his day! Charles Baudelaire despised photography as being a product of industry. He felt it provided an impression of reality that did not have the 'spiritual momentum' which came from the imagination. Whilst reviewing a photographic exhibition in 1859, clearly saw the need to put photography firmly in its place: "If photography is allowed to supplement art in some of its functions, it will soon have supplanted or corrupted it altogether....its true duty..is to be the servant of the sciences and arts - but the very humble servant, like printing or shorthand, which have neither created nor supplemented literature.... "Let it rescue from oblivion those tumbling ruins, those books, prints and manuscripts which time is devouring, precious things whose form is dissolving and which demand a place in the archives of our memory - it will be thanked and applauded. But if it is allowed to encroach upon the domain of the... imaginary, upon anything whose value depends solely upon the addition of something of a man's soul, then it will be so much the worse for us." Some painters dubbed the new invention "the foe-to-graphic art." Certainly those artists who specialised in miniature portraits suffered; in 1810 over 200 miniatures were exhibited at the Royal Academy; this rose to 300 in 1830, but thirty years later only sixtyfour were exhibited, and in 1870 only thirty-three. On the other hand, the painter, Gustave Courbet, recognised photography as a useful aid in depicting motifs. However, his paintings seem to illustrate, by the thickness of colour, that he saw photography as consisting merely of a copy of reality, and that painting went much further. A number of artists, seeing the writing on the wall, turned to photography for their livelihood, whilst others cashed in on the fact that the images were in monochrome, and began colouring them in. Baudelaire's assertion that photography had become "the refuge of failed painters with too little talent" was rather unfair, but it is true that a number turned to this new medium for their livelihood. By 1860 Claudet was able to claim that miniature portraits were no longer painted without the assistance of photography. In any case, absolute likeness was not always what the sitter wanted. Alfred Chalon, one of the last miniaturists, when asked by Queen Victoria whether photography was a threat to miniature painting, replied "No Madam - photography can't flatter!" Lady Eastlake, wife of the Director of the National Gallery (who also was the first President of the Photographic Society) also had her reservations, claiming that whilst photography was more exact, it had also become less true, and that in portraiture the broad suggestion of form had been replaced by a fussy accumulation of irrelevant detail: "Every button is seen - piles of stratified flounces in most accurate drawing are there - but the likeness to Rembrandt and Reynolds is gone!" Clearly she did not share the dread that painting was an art of the past. However, a further blow to miniature portraiture was to come when the Carte-de-Visite craze began to develop. By 1857 an Art Journal was reporting that portrait photography was becoming a public nuisance, with photographers touting for custom (much as artists do today at the Montmartre, in Paris). "It has really now become a matter for Police interference both on the grounds of propriety and public comfort!" the writer thundered. In that same journal Francis Frith claimed that photography "has already almost entirely superseded the craft of the miniature painter, and is on the point of touching, with an irresistible hand, several other branches of skilled art." In 1865 Claudet, by then a respected photographer, came to the defence of photography, following a blistering article in a French journal: "One cannot but acknowledge that there are arts which are on their way out and that it is photography which has given them the death-blow! Why are there no longer any miniaturists? For the very simple reason that those who want miniatures find that photography does the job better and instead of portraits more or less accurate where form and expression are concerned, it gives perfectly exact resemblances that at least please the heart and satisfy the memory." An example of photography being used for this purpose can be seen in a portrait of Sir William Allen, by Sir John Watson Gordon (1837), Royal Academy; this clearly comes from an 1843 Calotype. See also Muybridge, whose work led to a change in the way artists painted horses on the move. Man Ray, born later than this period, made an interesting observation on this apparent controversy. Miniature painting, in fact, made a comeback at the turn of the century. Though photography was seen by some as the invention that was killing art, this is a one-sided view, because it also proved to be an aid to their work. Portrait photographers found that by employing photography the number of sittings required could be reduced or even eliminated. Joshua Reynolds sometimes needed up to fifty sittings for portraits; it is said that his painting of Sir George Beaumont had required twelve sittings for the painting of the cravat alone! A problem is that few painters would readily admit to using photography as an aid, almost as though this were a form of cheating! David Octavius Hill used photography to make a record of people to be painted, whilst in the 1860s Robert Howlett was employed to take photographs of groups of people attending the Derby from the top of a cab, these photographs later being used as group studies in William Powell Frith's painting "Derby Day." This however did not stop William Powell Frith from observing, thirty years later, that in his opinion photography had not benefited art at all. Others who used photography to assist them in painting included Negre, Tissot, Gaugin, Cèzanne, Lautrec, Delacroix and Degas. 124 ATGET, Eugene b. 12 February 1857; d. 4 August 1927 Eugene Atget studied acting and played with a theatre group in the suburbs of Paris, but had to abandon this in 1887 because of a recurrent throat infection. The following year he began to take photographs. Though he earned his living by taking photographs, he never described himself as a photographer, preferring "author-producer." He produced a documentary of the architecture and people of Paris, many of his pictures having been taken in areas shortly to be demolished. During the thirty years he worked, developed an extensive filing system for his many negatives and prints, and his legacy amounts to several thousand images. His street photographs were not very different from that of his contemporary Paul Martin, but he also revealed a remarkable capacity for "seeing" pictures. Whereas lesser mortals might take very similar photographs of well-known landmarks, one could picture Atget's attention being drawn by what they would regard as mundane situations. He would photograph the same subject from different viewpoints and at different times, demonstrating that two pictures of one subject can have very different meanings and appeal. Eugene Atget was a largely unknown character round which a number of myths have emerged: he is pictured as a tramp-like character wandering around with his camera, or a naive photographer who did not understand how much his work would command. He was certainly a very much underrated photographer, unknown during his lifetime, dying in total obscurity, but now acknowledged as one of the most outstanding of artists. If he was not a surrealist himself, he certainly influenced this movement. BRADY, Mathew b. 1823; d. Jan 15, 1896 Though Roger Fenton was the first to document war in photographs, Mathew Brady, who documented the American Civil War (1861-1865), was probably one of the greatest of photographic documentary photographers. In 1839 Brady met, and became a student to Samuel Morse. That same year he met Louis Daguerre and went back to the United States to capitalise upon the invention of the Daguerreotype, establishing what proved to be a highly successful Gallery. Another photographer in Brady's team was Timothy O'Sullivan, who worked for him until 1863. The process Brady's team used was the collodion one, invented by Frederick Scott Archer. The limitations of equipment and materials prevented any action shots, but such people brought back some seven thousand pictures which well portrayed the realities of war. Perhaps the most famous of these is "Harvest of Death" photographed by O'Sullivan. The New York Illustrated News for 26 March 1851 reads: "M.B. BRADY, Esq., the eminent daguerreotypist, has lately opened a new saloon for the purposes of his art, in one of the best buildings on Broadway, New York. On the occasion of the first opening, a large number of ladies and gentlemen, comprising many distinguished persons, were invited, and partook of Mr. Brady's hospitality at a splendid dinner. The saloon is one hundred and fifty feet long, finished and furnished in the most costly manner. Mr. Brady is one of the oldest daguerreotype artists in the country, and one of the most successful, too. He is the author of many valuable improvements connected with the art, his pictures having a world-wide fame for fidelity and elegance." In 1856 William Gardner , a Scot, joined him, and the company's success became even more marked. Brady himself did not take many of the photographs which bear his name; he had set himself up as a portrait photographer, and had equipped a number of photographers (twenty, it is said) with what were to become known as "What-is-it?" darkroom wagons to cover the War, with the ruling that his name, as employer, rather than the names of the photographers themselves, would appear on the photographs themselves. A comment attributed to Brady is "The camera is the eye of history." He clearly saw his mission as that of a photographic historian, and our knowledge of this important era of American history is the better for it. The New York Times, 20 October 1862 commented on the display of pictures taken at Antietam: "Mr. Brady has done something to bring home to us the terrible reality and earnestness of war. If he has not brought bodies and laid them in our door-yards and along the streets, he has done something very like it...." Perhaps they were too real and detailed. The editorial continued: "These pictures have a terrible distinctness. By the aid of the magnifying-glass, the very features of the slain may be distinguished. We would scarcely choose to be in the gallery, when one of the women bending over them should recognise a husband, son, or a brother in the still, lifeless lines of bodies, that lie ready for the gaping trenches." Though Brady's work was much admired at the time, he gained little in financial terms; tired of this long war, people did not want reminders of it and whereas Fenton had clearly taken 125 his pictures with an eye to selling them, Brady's were honest sometimes brutally so, and people no longer wanted his pictures. Brady had invested a fortune into this business, but faced bankruptcy. In 1875 Congress purchased his archive of photographs for $2,840 at public auction, and granted him $25,000, but this was not enough to cover his debts, and he died alone, an alcoholic, and penniless. "No one" he said " will ever know what I went through to secure those negatives. The world can never appreciate it. It changed the whole course of my life." Though financially his enterprise failed, Mathew Brady had a significant effect on the art of photography, demonstrating that war photographs need not necessarily be purely posed ones. His work represents the first instance of what one may call documentary photography. From 1845 Brady had embarked upon an ambitious project to photograph many famous people of the time, and in 1850 published "A Gallery of Illustrious Americans. Among his portraits was one of Abraham Lincoln, which was reproduced and circulated during Lincoln's first Presidential campaign. Lincoln himself was to declare later: "Make no mistake, gentlemen, Brady made me President!" The majority of Brady's vast collection may be seen in the House of Congress in Washington. CAMERA LUCIDA The Camera Lucida, designed in 1807 by Dr. William Wollaston, was an aid to drawing It was a reflecting prism which enabled artists to draw outlines in correct perspective. No darkroom was needed. The paper was laid flat on the drawing board, and the artist would look through a lens containing the prism, so that he could see both the paper and a faint image of the subject to be drawn. He would then fill in the image. However, as anyone who has tried using these will know only too well, that too required artistic skills, as Fox Talbot also discovered. See also Camera Obscura. CAMERA OBSCURA The Camera Obscura (Latin for Dark room) was a dark box or room with a hole in one end. If the hole was small enough, an inverted image would be seen on the opposite wall. Such a principle was known by thinkers as early as Aristotle (c. 300 BC). It is said that Roger Bacon invented the camera obscura just before the year 1300, but this has never been accepted by scholars; more plausible is the claim that he used one to observe solar eclipses. In fact, the Arabian scholar Hassan ibn Hassan (also known as Ibn al Haitam), in the 10th century, described what can be called a camera obscura in his writings; manuscripts of his observations are to be found in the India Office Library in London. The earliest record of the uses of a camera obscura can be found in the writings of Leonardo da Vinci (1452-1519). At about the same period Daniel Barbaro, a Venetian, recommended the camera as an aid to drawing and perspective. He wrote: "Close all shutters and doors until no light enters the camera except through the lens, and opposite hold a piece of paper, which you move forward and backward until the scene appears in the sharpest detail. There on the paper you will see the whole view as it really is, with its distances, its colours and shadows and motion, the clouds, the water twinkling, the birds flying. By holding the paper steady you can trace the whole perspective with a pen, shade it and delicately colour it from nature." In the mid sixteenth century Giovanni Battista della Porta (1538-1615) published what is believed to be the first account of the possibilities as an aid to drawing. It is said that he made a huge "camera" in which he seated his guests, having arranged for a group of actors to perform outside so that the visitors could observe the images on the wall. The story goes, however, that the sight of up-side down performing images was too much for the visitors; they panicked and fled, and Battista was later brought to court on a charge of sorcery! In his essay "On the form of the Eclipse" he wrote: "The image of the sun at the time of the eclipse, unless it is total, demonstrates that when its light passes through a narrow, round hole and is cast on a plane opposite to the hole it takes on the form of a moon-sickle. Though Battista's account is wrapped up in a study of the occult, it is likely that from that time onwards many artists will have used a camera obscura to aid them in drawing, though either because of the association with the occult, or because they felt that in some way their artistry was lessened, few would admit to using one. Several are said to have used them; these include Giovanni Canale - better known as Canaletto (1697- 1768), Vermeer (1632-1675), Joshua Reynolds (1723-1792), and Paul Sandby (1725-1809), a founding member of the Royal Academy. The image of the sun shows this peculiarity only when the hole is very small. When the hole is enlarged, the picture changes... ." Though some, including Joshua Reynolds, warned against the indiscriminate use of the camera obscura, others, notably Algarotti, a 126 writer on art and science and a highly influential man amongst artists, strongly advocated its use in his Essays on Painting (1764): "the best modern painters among the Italians have availed themselves of this contrivance; nor is it possible that they should have otherwise represented things so much to the life... Let the young painter, therefore, begin as early as possible to study these divine pictures... Painters should make the same use of the Camera Obscura, which Naturalists and Astronomers make of the microscope and telescope; for all these instruments equally contribute to make known, and represent Nature." About the same time, the lens was being developed. Once again Roger Bacon's name is associated with this; some have claimed that it was he who invented spectacles. Gerolomo Cardano (1501- 1576), an Italian mathematician, introduced a glass disc in place of a pinhole in his camera, and Barbaro also used a convex lens. Why the name lens? It is claimed that because Italian lenses were by-convex, they seemed to resemble the brown lentils they used to make soup - so the lens came from the Latin for lentil. The first cameras were enormous. Athanasius Kircher (1601-1680) in a book written in 1646, described one which consisted of an outer shell with lenses in the centre of each wall, and an inner shell containing transparent paper for drawing; the artist needed to enter by a trapdoor. Other versions also appeared. Sedan chairs were converted, and tent-type cameras were also in use - even up the beginning of the nineteen hundreds. Then smaller, portable ones were made. Thus the camera obscura, as it came to be known, became a popular aid to sketching. Another aid to drawing, but which worked in a different way, was the Camera Lucida, designed in 1807. To give some idea of costs in the earliest days of photography, it is known that in 1839 Fox Talbot bought several instruments including a camera obscura for seven pounds fifteen shillings (£7.75). At that time the typical servant's wage would have averaged between ten and twenty pounds per year. CAMERA WORK This is the title given to an influential quarterly journal which appeared in 1903 in the wake of the PhotoSecession movement. It was edited by Alfred Stieglitz, and among the many contributors were Frank Eugene, Clarence White and Edward Jean Steichen. The first edition reads: "Only examples of such work as gives evidence of individuality and artistic worth, regardless of school, or contains some exceptional feature of technical merit, or such as exemplifies some treatment worthy of consideration, will find recognition in these pages." This magazine was beautifully produced. Some of the pictures were printed on fine Japanese tissue, and pasted in by hand. Many of the articles were written by leading authors. The reception by British photographers to the publication was immediately favourable. That same year "Photography" reported: "There can be no other verdict but that Camera Work beats all previous records for dignity, good taste, and...value." "Amateur Photographer" for 1st January 1903 also was full of praise. (See Stieglitz). There were in total fifty editions. The last publication was in June 1917, when the Photo-Secession movement had begun to lose its way. The script clearly shows that further editions were at the planning stage. The June edition contains a letter (17 November 1916), addressed to Stieglitz, from Frank Eugene, which reads as follows: "I have not received Camera Work for a very long time, probably due to the war, censorship, etc. etc.... The older I grow the more I appreciate what you have accomplished with your very wonderful publication. When I see you I shall be delighted to tell you how largely the possession of Camera Work has helped me in my work as a teacher, and what an incentive it has always been to my pupils towards a higher standard. It does...for the man with the camera, what the Bible has...for centuries, tried to do for the man with the conscience...." Sadly this, the fiftieth edition, turned out to be the last of this remarkable series, of which few copies now remain. CAMERON, Julia Margaret b. 11 June 1815; d. 26 January 1879 Julia Margaret Cameron was an English photographer known for her portraits of eminent people of the day, and for her romantic pictures which, despite their technical imperfections, stand the test of time. Her involvement in photography came about as a result of the kindness of her eldest daughter. Julia Margaret, by this time was aged forty-nine, her children had grown up, and her husband was often abroad on business. As a result she suffered from loneliness, and her daughter, to make her life more fulfilling, bought her a camera. From this simple beginning a new hobby began, which was to turn into an obsession. The comments in her book give a delightful glimpse of this lady: "I longed to arrest all beauty that came before me, and at length the longing has been satisfied. Its difficulty enhanced the value of the pursuit. I began with no knowledge of the art. I did not know where to place my dark box, how to focus my sitter, and my first picture I effaced to my consternation by rubbing my hand over the filmy side of the glass..." "I turned my coal-house into my dark room, and a glazed fowl-house I had given to my children became my glass 127 house! The hens were liberated, I hope and believe not eaten. The profit of my boys upon new laid eggs was stopped, and all hands and hearts sympathised in my new labour, since the society of hens and chickens was soon changed for that of poets, prophets, painters and lovely maidens...." As to the delight that her first successful portrait brought her...... "I took one child... appealing to her feelings and telling her of the waste of poor Mrs. Cameron's chemicals and strength if she moved. The appeal had its effect, and I now produced a picture which I called "My first success." "I was in a transport of delight, I ran all over the house to search for gifts for the child. I felt as if she entirely had made the picture. I printed, toned, fixed and framed it, and presented it to her father that same day: size 11 by 9 inches." "Sweet, sunny haired little Annie! No later prize has effaced the memory of this joy....." It has to be said that Julia Margaret Cameron was not the best of technicians. Some of her negatives show uneven coating of collodion, and above all, dust particles. Many of her prints are faded. Indeed, a critical entry in the Photographic Journal commented: "Mrs. Cameron will do better when she has learned the proper use of her apparatus." Lewis Carroll's comments were in the same vein: "In the evening Mrs. Cameron and I had a mutual exhibition of photographs. Hers are all taken purposely out of focus - some are very picturesque - some merely hideous however, she talks of them as if they were triumphs of art." Nevertheless, Cameron had a tremendous capacity to visualise a picture, and her portraits show a measure of vitality which the work of many others of the time did not. Among her most famous portraits are those of Herschel and Tennyson. She was greatly appreciated abroad, and won a number of major prizes. No less a person than Victor Hugo, the poet, wrote "No one has ever captured the rays of the sun and used them as you have. I throw myself at your feet". She must also have been a tremendously magnetic personality; Benjamin Jowett wrote of her: "Perhaps she has a tendency to make the house shake the moment she enters, but in this dull world that is a very excusable fault". She was also influenced by the PreRaphaelite school, which sought to return to artistic practices of Europe in late Mediaeval times; a classic example is the delightful portrait of Alice Liddell (on whom the story of Alice in Wonderland is based), entitled "Alethea." Another is the "Kiss of Peace." Many of her photographs of women and children are undisguisedly sentimental, others are delightful and penetrating studies. photography, or rather the lack of it; Thomas Sutton wrote of her work: "Admirable, expressive and vigorous, but dreadfully opposed to photographic conventions and proprieties" whilst The Photographic Journal for 15 February 1865 reads: "Mrs. Cameron exhibits her series of out of focus portraits of celebrities. We must give this lady credit for daring originality but at the expense of all other photographic qualities." The Photographic News, 20 March 1868, reporting upon one of her exhibitions in London, reads: We tend to remember her best pictures. Some, to put it mildly, were pretty awful. "Idylls of the King" , for example, has a very poor attempt at a moon on the top left, and cheesecloth to represent water, whilst "The Passing of Arthur" almost verges on the ridiculous! Looking beyond the banal, some remain as rather lovely pictures; an example is "Venus Chiding Cupid and Removing His Wings." "There is, in many cases, much evidence of art feeling, especially in the light and shade, and composition... often being awkward. The subjects... such as Sir John Herschel, Henry Taylor, Holman Hunt, Alfred Tennyson and others - are full of interest in themselves, and are often noble in form and appearance, a circumstance which alone gives value to the exhibition. Not even the distinguished character of some of the heads serve, however, to redeem the result of wilfully imperfect photography from being altogether repulsive: one portrait of the Poet Laureate presents him in a guise which would be sufficient to convict him, if he were ever charged as a rogue and vagabond, before any bench of magistrates in the kingdom......." One of photography's eccentrics, her work is still admired and greatly sought-after today. In her book "Annals of my Glass House", which was unfinished, she wrote of the distinguished people who faced her camera: Her force of personality made her a formidable photographer, capable of bullying anyone, however famous, into submission. Sitting for her could be quite an ordeal. Tennyson once brought Longfellow to her studio, warning him: "When I have such men before my camera my whole soul has endeavoured to do its duty towards them, in recording faithfully the greatness of the inner as well as the features of the outer man" "Longfellow, you will have to do whatever she tells you. I shall return soon and see what is left of you." Exposures lasting between one minute and as many as seven, the fact that the pictures show such lack of self consciousness may be largely due to her overpowering personality. The photographic press spoke harshly of her technical mastery of Commenting about a portrait of Wilfred Ward, she once wrote to a friend: "I counted four hundred and five hundred and got one good picture. 128 Poor Wilfrid said it was torture to sit so long, that he was a martyr! I bid him be still and be thankful. I said, I am the martyr. Just try the taking instead of the sitting!" Because she believed in subdued lighting and had large photographic plates, exposures could last several minutes. After each picture had been taken she would disappear into her coal-cellar cum darkroom, to prepare another plate, her victims having been warned not to move a muscle. She was clearly supported by a longsuffering family. In her book she writes: "Personal sympathy has helped me on very much. My husband from first to last has watched every picture with delight, and it is my daily habit to run to him with every glass upon which a fresh glory is newly stamped, and to listen to his enthusiastic applause. This habit of running into the diningroom with my wet pictures has stained such an immense quantity of table linen with nitrate of silver, indelible stains, that I should have been banished from any less indulgent household...." Cameron received honours abroad, but recognition did not come easily at home. She wrote: "The Photographic Society of London in their Journal would have dispirited me very much had I not valued that criticism at its worth. It was unsparing and too manifestly unjust for me to attend to it...." She presented an album to Sir John Herschel; this is now in the National Portrait Gallery in London. Julia died in Ceylon in January 1879. In a lengthy obituary The Times gives a vivid picture of this remarkable lady: "Mrs. Cameron appealed to a..wide...public by her pefectly original and unique photographic work and subject pictures in which, after a daring fashion of her own, forfeiting the sharpness of definition which ordinary photographers strive for, and which is one of the things artists most dislike in photographic portraiture...she produced a series of heads and groups... unique in their suggestiveness... very popular, and the process is still used occasionally. Mrs. Cameron's singular ardour of enthusiasm, the energy with which she flung herself into whatever she undertook, her rare forgetfulness of self and readiness to help others, endeared her to a wide circle of friends. CARTE-DE-VISITE photography Cartes-de-visite were small visiting card portraits (usually measuring 4 1/2 x 2 1/2") introduced by a Parisian photographer, Andre Disdéri, who in late 1854 patented a way of taking a number of photographs on one plate (usually eight), thus greatly reducing production costs. (He was not actually the first to produce them; this honour belongs to an otherwise obscure photographer called Dodero, from Marseilles). ...so full of life and energy, so ripe with plans and projects, so buoyant of spirits, so vivid in her interests, so keen in her friendships, and so overflowing in her friendliness." The Royal Photographic Society owns nearly 800 of her albumen and carbon prints and portraits, together with a handwritten manuscript of her autobiography. Different types of cameras were devised. Some had a mechanism which rotated the photographic plate, others had multiple lenses which could be uncovered singly or all together. CARBON process Print fading was a common occurrence in the earliest days of photography, and several people sought to address themselves to this problem. In the mid 1850s some began to experiment with carbon, and in 1864 Joseph Wilson Swan perfected the process, which he also patented. The carte-de-visite did not catch on until one day in May 1859 Napoleon III, on his way to Italy with his army, halted his troops and went into Disdéri's studio in Paris, to have his photograph taken. From this welcome publicity Disdéri's fame began, and two years later he was said to be earning nearly £50,000 a year from one studio alone. ** Prints made using this process came in any colour, and were permanent. The sensitising solution consisted of a mixture of carbon, gelatin, the colouring material, and potassium bichromate. Once the paper was exposed to light, the areas exposed became insoluble in water. Development consisted of washing the unexposed soluble material away in warm water. In England carte-de-visite portraits were taken of Queen Victoria and Prince Albert. One firm paid a small fortune for exclusive rights to photograph the Royal Family, and this signalled the way for a boom in collecting pictures of the famous, or having one's own carte-de-visite made. It is said that the portraits of Queen Victoria and the Royal Family taken by John Mayall sold over one hundred thousand copies. The image being laterally reversed, it needed to be transferred to another base which was usually paper, but which could be leather or wood; the image was in relief. A variation on the carbon process was the Woodburytype, introduced a year later. Prints made by this process would come in any colour, and were permanent. Carbon prints became Other public figures were often persuaded to sit. Helmut Gernsheim, a writer on the history of photography, comments that they were called "sure cards" because one could be sure that each time a famous person consented to sit, a small fortune would go to the photographer! To print quickly, several negatives were taken at a sitting: the Photographic News for 24 September 1858 reported that no fewer than four dozen negatives were taken of Lord Olverston at one sitting! 129 During the 1860s the craze for these cards became immense. An article in the Photographic Journal, reports: "The public are little aware of the sale of the cartes de visite of celebrated persons. As might be expected, the chief demand is for members of the Royal Fanily.... No greater tribute to the memory of His late Royal Highness the Prince Consort would have been paid than the fact that within one week of his decease no less than 70,000 of his cartes de visite were ordered... Our great thoroughfares are filled with photographers; there are not less than thirty-five in Regent Street alone." Sometimes the profits could be huge. A Frenchman by the name of Oliver Sarony, who was based in Yorkshire, was said to be earning more then ten thousand pounds a year - a fortune last century. Little wonder that there was speculation that Gladstone might introduce a tax on the trade! By the way, pirating of someone else's work is not new; some firms copied the photograph of a famous person and made quite a healthy living! The reasons for the success of these cards were their cheapness. The average price for a card was a shilling (5p); mass produced ones could be bought for 25p a dozen they were small, light and easy to collect, and many people began to place these in photographic albums collections of pictures, particularly of royalty, became highly treasured (there was no television, of course, in those days!) Cartes-de-visite were Albumen prints, and it is on record that in Britain half a million eggs were being delivered yearly to one photographic studio alone! The props used in cartes-de-visite seemed to follow certain fashions; starting off with balustrades and curtains, they moved to columns (sometimes resting on the carpet!) bridges and stiles, hammocks, palmtrees and bicycles. Sadly, quantity rather than quality was the order of the day, though there are some striking exceptions. To some extent the carte-de-visite craze also put paid to photography in which detail was a distinctive feature; the work of Gustave Le Gray and of the Bisson brothers, for example, could not be reproduced on these small cards, and thus their businesses began to fall off. By 1860 the carte de visite craze had reached its climax. In his autobiography H. P. Robinson states that in 1859 his photographic business had been about to collapse, but that this innovation had saved it. By the end of 1860 he had not only paid off old debts and made additions to his premises, but had invested a considerable sum of money, two years later being able to sell his business and retire to live in London. In May 1862, Marion & Co. announced that it had published a series of Cabinet views, 6.75 x 4.5 inches, photographed by George Washington Wilson, and the larger Cabinet photographs remained in vogue until the postcard was introduced at the turn of the century. Stereoscopic cards, whose popularity had temporarily declined, also began to experience a revival. There are many examples of these photographs in the Royal Photographic Society's collection. Some on current display are accompanied by an advertisement by the London Stereoscopic Society, for twenty prints at one pound, "Detention 3 minutes." ** This story about Napoleon stopping for a portrait has subsequently shown to be untrue, but it makes a good story and may have been put about purely for publicity purposes! COBURN, Alvin Langdon b. 11 January 1882; d. 23 November 1966 Coburn was another outstanding photographer who still, perhaps, is not given the acclaim he deserves. He was born in Boston, moving to England as a young man. He began taking photographs at the age of eight (inspired by his cousin F. Holland Day, became a founder-member of PhotoSecession and in 1903 was elected to the Linked Ring, and at the early age of twenty-five had exhibited a oneman show at the Royal Photographic Society. Coburn stressed the importance of learning the techniques of photography so that they became totally automatic, "leaving the mind free to devote itself to the really important matter: direct contact with what we wish to express." Coburn made a number of urban landscape pictures, with a definite mood. He was also an accomplished portrait photographer, and in 1913 and 1922 produced a two-volume collection of photographs of celebrities, entitled "Men of Mark." He has a characteristic style in his portraits. The writer George Bernard Shaw, who sat for Coburn, and who also had developed an interest in photography, described him as "one of the most accomplished and sensitive artist photographers...living." Coburn passionately believed in liberating photography from the notion that it is only artistic if it depicted reality, and he is perhaps best known for producing Vortographs, nonobjective photographs of such items as a piece of wood or crystal, through an arrangement of mirrors, resulting in multiple images. In 1916 Coburn designed an item the poet Ezra Pound called a Vortoscope, which consisted of three mirrors arranged like a kaleidoscope, which enabled multipleimage photographs to be taken. The British Journal of Photography (16 February 1917) comments on Coburn's fascination for his vortographs, and his assertion that the creating of these "was the most thrilling experience he had ever had in all the realms of photography. For over a quarter of a century he had been using a camera 130 in one way or another, but never had he discovered a medium to compare with vortography for producing aesthetic excitement and enjoyment." COLLODION process This process was introduced in 1851 and marks a watershed in photography. Between 1903-1909 his work appeared in three editions of Camera Work. Unfortunately Coburn lost himself in astrology and the occult, and his enthusiasm for photography waned somewhat after the first world war, though he again began taking photographs in the 1950s. Up till then the two processes in use were the daguerreotype and the calotype. Daguerreotypes were better than calotypes in terms of detail and quality, but could not be reproduced; calotypes were reproducible, but suffered from the fact that any print would also show the imperfections of the paper. Thanks to the close friendship between Coburn and Dudley Johnston, Curator of the Royal Photographic Society's Collection, the Society owns a considerable number of his fine works. The search began, then, for a process which would combine the best of both processes - the ability to reproduce fine detail and the capacity to make multiple prints. The ideal would have been to coat light sensitive material on to glass, but the chemicals would not adhere without a suitable binder which obviously had to be clear. At first, Albumen (the white of an egg) was used. Then in 1851 Frederick Scott Archer came across collodion. Collodion was a viscous liquid guncotton dissolved in ether and alcohol - which had only been invented in 1846, but which quickly found a use during the Crimean war; when it dried it formed a very thin clear film, which was ideal for dressing and protecting wounds. (One can still obtain this today, for painting over a cut). Collodion was just the answer as far as photography was concerned, for it would provide the binding which was so badly needed. Lewis Carroll, himself a photographer who used collodion, described the process in a poem he called "Hiawatha's Photography." "First a piece of glass he coated With Collodion, and plunged it In a bath of Lunar Caustic Carefully dissolved in water; There he left it certain minutes. Secondly my Hiawatha Made with cunning hand a mixture Of the acid Pyro-gallic, And the Glacial Acetic, And of alcohol and water: This developed all the picture. Finally he fixed each picture With a saturate solution Of a certain salt of Soda...." This "soda" was, of course, hypo. Sometimes potassium cyanide was used, the advantage of this being that the solutions could be washed out by rinsing under a tap for a minute or so, whereas hypo would need much more washing time. The collodion process had several advantages. being more sensitive to light than the calotype process, it reduced the exposure times drastically - to as little as two or three seconds. This opened up a new dimension for photographers, who up till then had generally to portray very still scenes or people. because a glass base was used, the images were sharper than with a calotype. because the process was never patented, photography became far more widely used. the price of a paper print was about a tenth of that of a daguerreotype. There was however one main disadvantage: the process was by no means an easy one. First the collodion had to be spread carefully over the entire plate. The plate then had to be sensitised, exposed and developed whilst the plate was still wet; the sensitivity dropped once the collodion had dried. It is often known as the wet plate collodion process for this reason. The process was labour-intensive enough in a studio's darkroom, but quite a feat if one wanted to do some photography on location. Some took complete darkroom tents, Fenton took a caravan, and it is no mere coincidence that many photographs taken in this period happened to be near rivers or streams! Moreover, at this time there were no enlargements, so if one wanted large prints, there was no alternative but to carry very large cameras. (It is such limitations of the process that make the work of people like the Bisson brothers, Fenton, and others so remarkable). 131 One might also mention the safety factor. The collodion mixture was not only inflammable but highly explosive. It is reported that several photographers demolished their darkrooms and homes, some even losing their lives, as a result of careless handling of the photographic chemicals. Despite the advantages the collodion process offered, there were still many who stoutly defended the calotype. A writer in the Journal of the Photographic Society (December 1856) wrote: "for subjects where texture, gradations of tint and distance are required, there is nothing.... to compare with a good picture from calotype or waxed paper negative." Moreover, the calotype process was less of an ordeal, especially for travel photographers; paper negatives could be prepared at home, exposed on location, and then developed upon one's return. Hence Diamond used the calotype process for some of his travel photographs, though he used collodion for portraiture and for his medical photography. Nevertheless the invention of this process turned out to be a watershed as far as photography was concerned: cheaper alternatives, such as Ambrotypes and Tintypes were developed. The former was a positive on glass, the latter a positive on metal; stereoscopic photography began to flourish; the carte-de-visite craze started; because of the faster speed of the process, the analysis of movement (see Muybridge) became possible. The use of collodion caught on very quickly indeed, and within a few years few people used either the Daguerreotype or Calotype process. The records of the Photographic Society give an interesting account of the efforts to ensure even sensitivity of the Collodion plates. As mentioned above, these plates had to be dipped into a nitrate of silver bath and exposed whilst still wet. Exposure would have to be almost immediate as otherwise the top of the plate would lose its moisture and the sensitivity would become uneven. All sorts of liquids were tried, including honey, beer, and even rasperry syrup! A variation on this was the Oxymel process. COLOUR, Photography Though the invention of photography had an immediate impact on the whole art world, the early photographs were in monochrome. As an additional service, daguerreotypes could be hand- painted, which kept a number of painters of miniatures in business. However, it was to be some time before colour photography was to become a reality. In the 1860s James Clerk Maxwell, using as a subject a tartan ribbon, showed that three monochrome images could be formed of a subject, each one taken using a different colour filter (red, blue and green). By projecting these images using three lanterns, each equipped with a corresponding filter, the colours could be recreated. The results were somewhat disappointing to Maxwell and his collaborator Thomas Sutton, but nevertheless they deserve the credit for laying the foundations of trichromate colour photography. Interestingly, strictly speaking this experiment should never have worked! Maxwell did not know this, but at that time the emulsion in use only responded to light at the blue end of the spectrum. So how could anything have been recorded on the "red" and "green" slides? It was not until one hundred years later that when the experiment was repeated, it was discovered that the green filter had also passed some blue light, whilst the ribbon's red colours were also reflecting ultra-violet rays, which had been recorded on the red plate. However, though this (by sheer coincidence) produced the right effect, it does not detract from Maxwell's discovery, for with an appropriate emulsion responding to all colours the method works well. In 1873 Herman Vogel discovered sensitising dyes, which was a step forward in the pursuit of full colour photography. As a result of his work, "orthochromatic" plates, sensitive to all colours with the exception of red, were produced. When in 1906 "panchromatic" films, sensitive to all colours, came into production, some photographers began taking three "separation" negatives, using a viewer which enabled one to see all three slides superimposed upon one another. In 1907 Auguste and Louis Lumière produced plates they called Autochrome, using a different system from that above. The colours appeared in delicate pastel shades, often looking very dark, but were well received at the time. Back in 1869 Ducas du Hauron had published a book offering another method - the subtractive one - by which colour could be re-created. One of his suggestions had been that instead of mixing colour lights, one could combine dyed images; film could be coated with three very thin layers of emulsion, each sensitive to the primary colours; once processed as positives, the transparency could then be viewed as a full colour photograph. At the time, however, the emulsions were such that none of his proposals could be tested. It was not until the mid 1930s that Kodak was to produce a film based on this principle, to be named Kodachrome; up till then the additive methods suggested by Maxwell had been used. COMBINATION PRINTING In the early days of photography the material of the time was not sensitive to red; it was highly sensitive to blue, and therefore blue sky was rendered in a very light tone. Most of the photographs taken in the 40s and 50s were usually of foreground landcapes with blank skies - very little detail (if any) in the sky. Roger Fenton, an architectural and landscape photographer and one of the fine photographers of this period, did a lot of experimental work on this. The solution he adopted was to make negatives a little thin in the foreground and then to over-expose when making the prints. This however was not an ideal solution, and it was the problem of this attempt to record sky that led photographers to probably one of the most interesting early concepts in photography which we now call "combination printing." Combination Printing is the term given to the technique of making pictures from more than one negative or print. It can take various forms: printing two or more negatives, one after the other, on the sheet of paper; superimposing two negatives, printing them both together; cutting out parts of a number of prints, and arranging, perhaps pasting them on card or photographed background, and then photographing the finished result (montage). Hippolyte Bayard was the first to suggest that separate negatives of clouds be used to print in the skies. However, others, particularly William Lake Price, began to explore the idea of using combination printing to produce compositions. The most famous of the early combination prints is "The two ways of life", by Rejlander, who masked all areas of the photograph other than the area being printed. Rather different is the technique by Henry Peach Robinson, who made photomontages; his classic example is "Fading Away." The CYANOTYPE process This is an early process first introduced by John Herschel in 1842. It is still in use today, and is more commonly known as the blue-print process. In the early days paper was impregnated with iron salts and then used in contact printing. The paper was then washed in water, and the image would come out as a white image on deep blue. Long expsoure times were required, but one advantage was that since the chemicals were mainly sensitive to Ultra-Violet rays, the solutions can be prepared in subdued light, rather than in a darkroom. One of the earliest users of the process was Anna Atkins, who produced the first photographically illustrated book. DAGUERRE, Louis Jacques Mande b. 18 November 1787; d. 10 July 1851 Daguerre (pronounced Dagair) was perhaps the most famous of several people who invented photography. He began work as an apprentice architect, and at the age of sixteen was an assistant stage designer in a Paris theatre, his elaborate stage designs winning him considerable acclaim. He had an astonishing ingenuity in the handling of light and lighting effects, and he supplied the scenic and lighting effects for a number of operas in theatres in Paris. He developed an impressive illusions theatre, which he termed Diorama; it was a picture show with changing light effects and huge paintings measuring 22 by 14 metres, of famous places. This became the rage in the early twenties. He regularly used a camera obscura as an aid to painting in perspective, and this had led him to seek to freeze the image. In 1826 he learned of the work of Nicephore Niépce, and on 4 January 1829 signed up a partnership with him. The partnership was a short one, Niépce dying in 1833, but Daguerre continued to experiment. He made an important discovery by accident. In 1835, so the story goes, he put an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latent image had developed. Daguerre eventually concluded that this was due to the presence of mercury vapour from a broken thermometer. This important discovery that a latent image could be developed made it possible to reduce the exposure time from some eight hours to thirty minutes. Though he now knew how to produce an image, it was not until 1837 that he was able to fix them. This new process he called a Daguerreotype. Daguerre advertised his process and sought sponsorship, but few seemed interested. He then turned to Francois Arago, a politician, who immediately saw the implications of this process, took his case up, and the French government commissioned a report on the process, to be chaired by Paul Delaroche. On 7 January 1839 an announcement was made of the discovery, but details were not divulged until 19 August when the process was announced publicly, the French government having bought the rights to the process from him, and given it free to the world. However, this process had also been patented in England and Wales on 14 August only five days previously. As Lady Eastlake pointed out: "...by some chicanery a patent for the daguerreotype was actually taken out in England, which for a time rendered this the only country which did not profit by the liberality of the French government. The early history of photography is not so generous in character as that of its maturity." From the day the announcement was made of this new discovery, the process came to be used widely. The claim was made that the daguerreotype "requires no knowledge of drawing...." and that "anyone may succeed... and perform as well as the author of the invention." The Literary Gazette for 7 January 1839 read: "Paris, 6th January 1839. We have much pleasure in announcing an important discovery made by M. Daguerre, the celebrated painter of the Diorama. This discovery seems like a prodigy. It disconcerts all the theories of science in light and optics and, if borne out, promises to make a revolution in the arts of design. rinsing the plate in hot distilled water. M. Daguerre has discovered a method to fix the images which are represented at the back of a camera obscura; so that these images are not the temporary reflection of the object, but their fixed and durable impress, which may be removed from the presence of those objects like a picture or an engraving." His first plates were 8 1/2" by 6 1/2"; it is interestting to note that this still remains the standard "whole-plate" today. An article in La Gazette de France, of the same date, also showed one of the limitations of the process: "Nature in motion cannot reproduce itself, or at least can do so only with great difficulty, by the technique in question. In one of the boulevard views.... it happened that all which moved or walked did not appear in the drawing...." The early daguerreotypes had several drawbacks. the length of the exposure necessary all but ruled out portraiture. The image was laterally reversed (as one sees oneself in a mirror). Many of the portraits reveal this from the way the coat was buttoned; if one required a picture the right way round, the camera would be pointed at a mirror reflecting the sitter's image. Initially this will not have bothered people, who were used only to seeing their mirror image in any case. it was very fragile. perhaps most limiting of all, it was a "once only" system; what was needed was a means whereby copies of a photograph might easily be made. Taken in 1839, this picture of a boulevard gives the impression of empty streets, because with long exposures moving objects would not register. Daguerre's choice of chemicals was such that the action of light left a milky white image or mercury amalgam. However, there was an exception when a man stopped to have his shoes shined, (see bottom left of the larger picture) and though he and the person shining the shoes remain anonymous, they may have the distinction of being the first people ever to have been photographed. In 1851 Daguerre died. In a sense this symbolically ended an era, for that very same year a new technique was invented, which was another milestone in photography - the wet collodion process by Frederick Scott Archer. The DAGUERREOTYPE This was a positive image on a metal support. The Daguerreotype was the first successful photographic process, the discovery being announced on 7 January 1839. The process consisted of exposing copper plates to iodine, the fumes forming light-sensitive silver iodide. The plate would have to be used within an hour. exposing to light - between 10 and 20 minutes, depending upon the light available. developing the plate over mercury heated to 75 degrees Centigrade. This caused the mercury to amalgamate with the silver. fixing the image in a warm solution of common salt (later sodium sulphite was used.) The quality of the photographs was stunning. However, the process had its weaknesses: the pictures could not be reproduced and were therefore unique; the surfaces were extremely delicate, which is why they are often found housed under glass in a case; the image was reversed laterally, the sitter seeing himself as he did when looking at a mirror. (Sometimes the camera lens was equipped with a mirror to correct this); the chemicals used (bromine and chlorine fumes and hot mercury) were highly toxic; the images were difficult to view from certain angles. Many of the daguerreotypes that remain are noticeable for their detail, and this caused quite a sensation at the time. Indeed, the Spectator (2 February 1839) called daguerreotypes the "self operating process of Fine Art." The reaction in America was also one of amazement. The Journal "The Knickerbocker" for December that year quoted: We have seen the views taken in Paris by the 'Daguerreotype,' and have no hesitation in avowing, that they are the most remarkable objects of curiosity and admiration, in the arts, that we ever beheld. Their exquisite perfection almost transcends the bounds of sober belief. Carl Dauthendey, a photographer who became the first professional daguerreotype photographer in St. Petersburg, makes an interesting comment on the way Daguerreotypes were viewed: 134 "People were afraid at first to look for any length of time at the pictures he produced. They were embarrassed by the clarity of these figures and believed that the little, tiny faces of the people in the pictures could see out at them, so amazing did the unaccustomed detail and the unaccustomed truth to nature of the first daguerreotypes appear to everyone" Sometimes the details might reveal something that the photographer had not intended. Fox Talbot, Daguerre's rival, observed: "It frequently happens, moreover - and this is one of the charms of photography - that the operator himself discovers on examination, perhaps long afterwards, that he has depicted many things that he had no notion of at the time. Sometimes inscriptions and dates are found upon the buildings, or printed placards most irrelevant, are discovered upon their walls: sometimes a distant dial-plate is seen, and upon it - unconsciously recorded - the hour of the day at which the view was taken." This capacity to record minute detail was put to good use by Jean Baptiste Louis Gros, an amateur who made the first images of the Parthenon whilst on a mission in Greece. On his return to Paris he discovered that on close inspection details which he had not observed could be examined, including the minutest sculptural elements. In the museum at the Royal Photographic Society one of Daguerre's cameras is displayed. It was used by Talbot for his own process. However, there is an interesting omission: Daguerre's cameras always had a label on the side, bearing his signature, but Fox Talbot appears to have removed this! One problem with early daguerreotypes was the length of exposure required - 10 to 15 minutes in bright sunlight. In fact, a daguerreotype in the International Museum in Rochester, depicting a chapel, states that the picture was taken between 4:40pm and 5:30pm on 19 April 1840. Such lengths were hardly suitable for portraiture. Fox Talbot noted in a letter dated 21 May 1852: "Ld Brougham assured me once that he sat for his Dabguerreotype portrait half an hour in the sun and never suffered so much in his life." To make photography possible, rests were used to keep the head still, and sitters had often to cope with brilliant sunlight. One photographer even used to run flour on the sitter's face, in order to reduce exposure time! There was clearly a need to find some more effective ways of reducing the exposure time: On the chemistry side, J.G. Goddard started using bromide as well as iodine to sensitise plates, while Antoine Claudet experimented using chlorine. On the optical side, J. M. Petzval invented a portrait lens with an aperture of f3.6 (as opposed to f14, which was currently being used.) Petzval's lens was still being widely used almost a century later. The daguerreotype, aptly called a "mirror with a memory", was an amazing development, and one cannot but marvel at the intricacy of the detail. However, it was a blind alley as far as photography was concerned. DEVELOPMENT The function of a developer is to convert the invisible (latent) image into a visible form. In the very earliest days of photography exposures had to continue until an image had been formed, hence the need for very long exposures. It is said that Daguerre discovered development accidentally, having placed some unsuccessful sensitised plates into a cupboard, and having returned later to discover that the plates bore an image. By further experimentation he concluded that the mercury in the same cupboard was responsible for producing the image. Fox Talbot also discovered that there was such a thing as a latent image that could be developed, and as a result was able to reduce drastically his exposure time - from as much as an hour to a minute or less. Taken together, these improvements enabled photographers to use exposures of between ten and thirty seconds, thus making portraiture more of a practical proposition. By March 1841 Beard had opened a studio at the Royal Polytechnic Institution, while Claudet opened one three months later, behind St. Martin's church, Trafalgar Square. In 1853 Daguerre's patent expired, and many daguerreotypists began to open for business. At that time, of course, all photographs were monochrome (it was not until after the time of Maxwell that colour photography became a possibility), so many artists turned to hand-colouring the photographs, which were almost invariably presented in ornate cases. Colouring was a skilled and delicate affair. Typical of the kits was the Newman kit, dated 1850, with thirtysix colours. The colours would be applied very carefully with a fine brush, and then fixed simply by breathing on the plate itself. 135 DOCUMENTARY PHOTOGRAPHY The history of photography is full of people who with great intensity put forward theories on the nature of photography, or who denigrated the work of others, or set up break-away groups. These people have their place, but fortunately there were others who avoided controversy and who set about recording the life and times of the period in which they lived, either from a sense of mission, or simply to leave an accurate version of their life and times for others. Up to the time photography was invented events were portrayed by means of painting, and whilst many of them evoke an emotional response it is difficult to be sure that what we are being presented with is not fanciful, incorrect, or even blatantly dishonest. There are, for example, so many different paintings of Queen Elizabeth I that it is not clear what she looked like! (See also Alfred Chalon's comments in Artists and Photography.) Photography does add to authenticity, but the oft-quoted adage that "the camera cannot lie" is a very misleading one. Even with "straight" photography (i.e. where neither negative not print has been retouched), there are many ways by which the process can be used to manipulate and mislead, for example by selection of viewpoint, or by using a picture out of context. Used honestly, however, photography has the capacity to capture a particular moment in time, to reproduce images in considerable detail, to overcome language barriers, and compellingly to draw attention to situations about which we might otherwise be unaware. This capacity was immediately recognised by early photographers DRY-PLATE process This was invented by Charles Bennett in 1878, coming soon after Dr. Richard Leach Maddox had suggested the use of Gelatin as a binder. This new process was revolutionary: from now on portable darkrooms would no longer be necessary; the process was much more sensitive to light, and therefore relatively fast shutter speeds were possible; it led to a greater degree of standardisation and quality a new range of cameras (including novel ones, such as used for example by Paul Martin), began to appear. EASTMAN, George b. 12 July 1854; d. 14 March 1932 Up to the time of Eastman photography, though already popular, was still considered too complicated for ordinary users, and George Eastman is remembered for having made photography accessible to all. Eastman started off as a bank clerk, and then became interested in photography. He is particularly remembered for introducing flexible film in 1884. Four years later he introduced the box camera incorporating roll film, and with his slogan "You press the button, we do the rest" he brought photography to the masses. The box camera had a simple lens focusing on 8 feet and beyond. One roll of film took a hundred images, all circular in shape. The entire camera would be posted to the factory where the film was processed and the camera re-loaded and returned to the user, the charge for this being £2.2s (£2.10). The photographs were of about 65mm diameter, and opened up a new world for popular photography. Eastman's contribution not only made photography available to all, but also resulted in a gradual change in what constituted acceptable photography. Paul Martin, who worked with a large portable camera, had found it difficult to get his informal pictures accepted at exhibitions. To have pictures accepted, he complained, one would need to take "... a noble and dignified subject, a cathedral or mountain..." and that "few envisaged the popular snapshot until the coming of the hand camera and the Kodak." From the age of 76 onwards, Eastman was becoming increasingly ill. Eventually, having settled his affairs, he took his own life. Next to his body was a note which said simply "To my friends, my work is done - why wait?" EMERSON, Dr. Peter Henry b. 13 May 1856; d. 12 May 1936 Many photographic historians claim that Peter Henry Emerson made a greater impression on Victorian photography than any of his contemporaries. An outstanding scholar, he practised medicine before abandoning it, at the age of 26, to take up photography. Though some of his work was included in books (he was an authority on wild life in Norfolk), he remained essentially an amateur. At this period perhaps the leading photographer of the day was Henry Peach Robinson, who had published an influential book, "Pictorial Effect in Photography" - a book which ran to several editions. Emerson condemned this book out of hand, particularly disliking the contrived photography by Robinson, Rejlander, and Julia Margaret Cameron and saw this approach as arresting the development of photography as a 136 medium in its own right, with no need to emulate styles of painting. Perhaps by then the time was right for a new approach. Photographic materials had evolved somewhat; new faster materials were appearing, making photography outdoors rather different from what it had been in earlier times. In 1886 he was elected to the Council of the Photographic Society, and embarked upon a series of lectures to put forward his views. Three years later he published an influential (if controversial) book entitled "Naturalistic Photography for students of Art" which one writer described as "like dropping a bombshell at a teaparty." In it he made the case for photography in which truth and realism would replace contrived photography. "Photograph people as they really are - do not dress them up" was his main message: "The photographic technique is perfect and needs no...bungling" He also very firmly rejected the retouching of pictures, which he called "the process by which a good, bad, or indifferent photograph is converted into a bad drawing or painting". In effect he was advocating that one should treat photography as a technique in its own right, and not to seek to imitate other art forms. Emerson also argued that a photographer should imitate the eye. He claimed that one only sees sharpness in the centre, and that the image is slightly blurred at the periphery, and therefore suggested that one should make a photograph slightly out of focus in order to achieve that effect, merely ensuring that the image in the centre is sharp. In his book he wrote: "Nothing in nature has a hard outline, but everything is seen against something else, and its outlines fade gently into something else, often so subtly that you cannot quite distinguish where one ends and the other begins. In this mingled decision and indecision, this lost and found, lies all the charm and mystery of nature" This was a new departure. Up till then photographers had tried to get everything sharp; they may not always have succeeded, but that was their objective. Now Emerson was advocation that photographers should not Some photographers greeted Emerson's ideas with enthusiasm, particularly George Davidson. Another was Frank Sutcliff, who had a studio at Whitby. However, his ideas did not go down well with other contemporaries. H.P.Robinson wrote: "Healthy human eyes never saw any part of a scene out of focus" whilst Emerson retorted, in an uncompromising manner: "I have yet to learn that any one statement of photography of Mr. H.P.Robinson has ever had the slightest effect on me except as a warning of what not to do...." advancement of artistic photography. Until then he had denounced medals, but in 1925, typical of his vanity, he then started awarding his own "Emerson" silver and bronze medals to others, some posthumously. Among the fifty-seven who gained his approval in this manner were Hill and Adamson, Nadar, Hippolyte Bayard, Julia Margaret Cameron, and an "unknown French photographer in Paris, 1865, for an unknown lady with a cigarette"! The reason for these awards never became clear; some have suggested that this was yet another way of perpetuating his name. Despite his egotism and unforgiving nature to those who disagreed with him, his work succeeded in laying down the foundations of a new, unsentimental type of work, and laying the groundwork for the PhotoSecession movement. and described Robinson's book (Pictorial Effect in Photography) as "the quintessence of literary fallacies and art anachronisms." Emerson was not the easiest of people to get on with, and was inclined not only to make sarcastic and vitriolic remarks but also to erupt into a fiery temper. His emphasis on technique is probably what led to his own undoing; he had begun to believe that photography could be reduced to technical rules and principles. Finding that he could not achieve this, he became frustrated and finally (possibly angered by the success of the Impressionism movement) he renounced naturalistic photography in a black-bordered pamphlet entitled "The death of Naturalistic Photography" (1890). He wrote: "I have...I regret it deeply, compared photographs to great works of art, and photographers to great artists. It was rash and thoughtless, and my punishment is having to acknowledge it now... In short, I throw my lot in with those who say that Photography is a very limited art. I deeply regret that I have come to this conclusion..." In 1895 Emerson was awarded the Royal Photographic Society's Progress Medal for work in the 137 ENLARGERS The earliest enlargers used direct sunlight, and thus came to be known as "solar cameras". It was an American, D.A. Woodward, who in 1857 first constructed an enlarger. It was a cumbersome object. The sun was collected by means of a convex lens, and the camera has to be turned with the sun. This design became the model for a number of solar cameras. The picture shows an advert for his cameras, and a medal that he had been awarded to him at a major exhibition. Another pioneer was Wothly, from Aachen, who made a few improvements to Woodward's solar camera, and exhibited portraits almost at life size. Wothly's solar camera was a monstrosity! The condenser had a diameter of 1 metre. The heat of the condensed rays of sun was such that one had to have water troughs built in. However, perhaps the first ever reference to an enlarging process can be attributed to Draper. In 1840 he wrote: "Exposures are made with a very small camera on very small plates. They are subsequently enlarged to the required size in a larger camera on a rigid stand. This method will probably contribute very much to the practice of the art." Louis Jules Duboscq (1817-1886) made an apparatus for enlarging by electric light, and showed it to the Paris Photographic Society in 1861. Eventually, of course, the solar camera disappeared from the photographic industry and was replaced by enlarging cameras that used arc lamps. As the sensitivity of papers increased, so it was possible to use other sources of light. However, even at the turn of the century it was possible to buy simple daylight enlargers. This one was made by Griffin and Sons. The advert. in the A.P. read as follows: Messrs. J. J. Griffith and Sons Ltd. have introduced an instrument which should find a cordial welcome at the hands of many an amateur who desires to make bromide enlargements without elaborate apparatus. They are inexpensive, and whilst folding into small space can be erected quickly and by one movement, there being no loose screws or bolts. .... Having set up the instrument, the user places his negative in the groove at the small end and sensitive paper in the box at the large end. The camera is then taken into daylight and exposed to the clear sky for a period varying between a few seconds and a minute or two. Upon development of the exposed paper a sharp, bright enlargement will be the result. The price of the enlarger to take quarter-plate and enlarge to whole plate, including meral exposure shutter and achromatic lens, is 12s 6d (62p). May we also ask your attention to our gaslight attachment for enlargers? This consists of a parabolic reflector, in from of which are fixed two incandescent gas burners of a special type. ... The attachment can be fitted to almost any enlarger on the market." (Cost, 10s 6d - 50p). FADING of prints Though (unlike Wedgwood), the early photographers had learned to remove the unused light-sensitive solutions by fixing prints, they still had a major problem in that many of the early photographs had a tendency to fade. So serious was the problem that in 1855 the Photographic Society formed a committee to examine the causes of fading; this committee, chaired by Roger Fenton, received support from an equally concerned Prince Albert, who contributed £50 to its funds. The major causes of fading which were identified by the committee included the presence of sulphur in the prints, the presence of fixer because of insufficient washing, and (in some instances) the type of mounting used. They recommended more careful washing of prints. Most members of the committee concluded that gold toning would enhance the life of prints (which indeed it did) and also that some experimenting with protective coatings on the print might be helpful. In 1856 Robert Howlett published a booklet on the preservation of prints. In the 1860s the carbon print process, using pigment, became popular, the process being perfected by Sir Joseph Wilson Swan in 1866. FENTON, Roger b. Mar 1819; d. 8 Aug 1869 Roger Fenton is particularly known for his coverage of the Crimean War, which is a pity, because it only formed a small proportion of his output in other areas, notably landscape photography, and also somewhat obscures the major part he played in promoting photography in general. After studying at London University, Fenton studied art in London, and later in Paris under the painter Paul Delaroche. However, having had little success as a painter, in 1844 he returned to London and studied law. In January 1851 he visited Paris, and was impressed by the freedom that photographers in France had been granted as a result of the Daguerreotype process having been made available to all. By contrast, progress in England was slow because of Talbot's claims arising from his patent. In 1852 he visited Russia, and his photographs were amongst the first ever to be seen in England, guaranteeing him instant fame. Back in England, he proposed the formation of a Photographic Society, and on 10 January 1853 this came into being, and he served as its Secretary for three years. (This is now the Royal Photographic Society). 138 Fenton photographed Queen Victoria's family, and also became the official photographer to the British Museum. The Crimean War (1853-1956) was one of many between Russia and the Turks, but this time involved the British and French. William Russell, a journalist working for The Times, and one of the first war correspondents, began to send a series of disturbing accounts of the conduct of this war, and particularly the conditions under which the British forces were fighting. Less than 20% of the fatalities of the forces were due to war wounds; the majority of these were caused by disease and the freezing cold. When Russell began to report the inadequacy of the medical facilities and the fact that British soldiers, not having even been issued with winter uniforms, were dying with cold, feeling over the government's handling of the war began to mount. In 1855, in response to this continuous criticism of the government's handling of the war, Fenton was commissioned to photograph it, and produced over 350 pictures of the conflict. Though he is seen as a war photographer, his pictures showed a very one-sided cosmetic view: as it was largely a propaganda exercise, he was bound to show the well-being of the troops; he wanted to sell his pictures, and gruesome realistic ones were probably not very marketable! many of his pictures were of the officers, a sign, perhaps, of his sound business sense! In fairness to him, he often felt obliged to photograph them: "If I refuse to take them," he complained, "I get no facilities for conveying my van from one locality to another." Fenton's war pictures, therefore, tend to portray war as a gorgeous pageant; there are no dead bodies, and one might almost imagine that the Crimean war was almost like a picnic. There are no action shots (this for technical reasons), but those of soldiers are carefully posed groups, almost as if they were cricketers just about to go in to bat. It is this bias which makes one question slightly whether he was a true war photographer in the same league as the Mathew Brady team. Moreover, as an agent of the government, his portrayals were somewhat slanted; the charge of the Light Brigade, for example, was one disaster that was depicted as a glorious event. for the dust thus raised to settle before coating a plate...." As the summer arrived, Fenton found that the developing liquid became so hot that he could hardly put his hands in it! He also had to stop work earlier and earlier each day, many of his portraits having been taken before seven o'clock in the morning. Upon returning from the Crimea (but not before he too had endured cholera) he had published bound volumes of his prints. However, they did not sell too well, as people hardly wished to keep mementos of an event which most would wish to forget. The picture shows an area of Balaklava. One has to bear in mind the considerable difficulties experienced at this time by photographers on location. Like all photographers of the time, he found it necessary to take with him all the sensitising and processing equipment. To do this, Fenton took with him a converted wine-wagon as a caravan, and this occasionally became the target, probably being mistaken for an ammunitions vehicle. In a lecture to the Photographic Society he gave an account of the conditions: "Though (the van) was painted a light colour externally, it grew so hot towards noon as to burn the hand when touched. As soon as the door was closed to commence the preparation of a plate, perspiration started from every pore; and the sense of relief was great when it was possible to open the door and breathe even the hot air outside." Fenton also had his own battles... Another reason for the lack of sales was that the prints, still on salted paper, had a tendency to fade. Fenton himself was sufficiently concerned about the fading of pictures, for he chaired a Photographic Society "Fading Committee." Fenton also produced a number of Stereoscopes of architecture, landscapes and still life subjects. He then produced a series of photographs of cathedrals. For reasons that are not clear, he gave up taking photographs in 1861 and returned to the law; it has been suggested that this was because of his dislike for the increasing commercialisation of photography It was probably his bout of cholera which led to his early death at the age of forty-nine. It is worth noting that this prolific output and contribution to photography was confined to just eleven years or so. Over six hundred of Fenton's prints are now preserved at the Photographic Museum in Bradford the most comprehensive archive of his work. "It was at this time that the plague of flies commenced. Before preparing a plate the first thing to be done was to battle with them for possession of the place. The necessary buffeting with handkerchiefs and towels having taken place, and the intruders having being expelled, the moment the last one was out, the door has to be rapidly closed for fear of a fresh invasion, and then some time allowed 139 FIXING Fixing is the process of removing from photographic materials the unused light-sensitive solutions, thus making the image more permanent. Had Thomas Wedgwood been able to fix his pictures, the invention of photography would have been attributable to him. However, it was not until after his death that Sir John Herschel discovered what Wedgwood had found so elusive. In a paper printed in the Edinburgh Philosophical Journal ( 8 January 1819) Herschel wrote "Muriate of silver (now known as silver chloride), newly precipitated, dissolves in this salt (hyposulphite)....almost as readily as sugar in water." Sodium thiosulphate (incorrectly known as Hypo) is still, in fact, a fixing agent used today. Though fixing made prints more stable, fading was at first a problem that needed to be addressed. One of the causes was inadequate washing of prints after processing. It was this instability that caused people to investigate more lasting processes such as the Carbon one. The introduction of GELATIN The development of the Collodion process marked a watershed in the development of photography. However, this wet-plate process had limitations, one being that it was necessary to keep the collodion moist. For a number of years several attempts were made to discover ways of keeping the collodion moist for long periods. The materials tried included unusual ones like licorice, beer and raspberry syrup! Some success was achieved by using a mixture of bromide in collodion. The ideal binder would be one which enabled the plates to be used only when dry. It was not until 1871 that the next breakthrough was achieved by Dr Richard Leach Maddox, when he began using gelatin. In fact, as far back as 1850 Robert Bingham had suggested the use of gelatin, but this idea had not been taken up at the time, presumably because of the announcement of the collodion process the following year. Gelatin is a protein obtained from animals, which is transparent and odourless, and used in a number of food processes. The first account of its use in photography is in the British Journal of Photography for 8 September 1871, when Maddox suggested that the sensitising chemicals could be coated on to a glass plate in a gelatin rather than a collodion emulsion. Maddox's process, though revolutionary, was far slower than collodion. Several manufacturers experimented with it, the most successful being Charles Bennett, who in 1878 announced a new gelatin dry plate process. This was a major breakthrough, particularly since Bennett's process also considerably enhanced the sensitivity of the emulsion, reducing the exposure time to one tenth of that required for the collodion one. This dry process relieved photographers of the need to carry about their own darkroom and chemicals; exposure could now be made on location, development being left until much later; it also let to a greater degree of standardisation, and a more scientific approach to photography; the science of sensitometry was introduced at around this period, and exposure calculators now began to appear. By the end of that decade the dry plate had superseded the Wet Plate entirely, and within a further ten years the emulsion could be coated on celluloid roll film. GUM BICHROMATE PROCESS The gum process was introduced in 1894, and was one of several introduced about this period, enabling photographers to obliterate many of the photographic qualities. A gum bichromate practitioner could alter the tones, get rid of details, and using a brush, pencil or rubber, could change an image so much that it looked more like a painting than a photograph. The paper would be coated with gum arabic mixed with a sensitive chemical, which would harden on exposure to light. The exposed gum layer containing a pigment was then washed with water, leaving the hardened parts behind. The print could then be treated with brushes and thus be modified considerably. Gum bichromate prints have little detail, but may sometimes appear almost like charcoal drawings. Stieglitz, writing about the process, said that in it "the artist has a medium that permits the production of any effect desired. These effects are so "unphotographic" in the popular sense of that word as to be described as illegitimate by those ignorant of the method of producing them. In this process the photographer prepares his own paper, using any kind of surface most suited to the result wanted, from the even-surfaced plate paper to rough drawing parchment; he is also at liberty to select the color in which he wishes to finish his picture, and can produce at will in india-ink, red-chalk or any other color desired. 140 The print having been made he moistens it, and with a spray of water or brush can thin-out, shade, or remove any portion of its surface. Besides this, by a system of recoating, printing-over, etc., he can combine almost any tone coloreffect." Light to the Purpose of Pictorial Representation," presented to the Royal Society on 14 March 1839. He also coined the terms "negative" and positive" in this context, and also the "snap-shot". One of the leading exponents of this process was Robert Demachy. It was eventually superseded by the bromoil one. HERSCHEL, Sir John Frederick William b. 7 March 1792; d. 11 May 1871 The only son of the distinguished British astronomer William Herschel, Sir John himself also became a wellknown astronomer, and published an influential book on the subject. He became interested in capturing and retaining images, and in 1839 had managed to fix pictures using hyposulphite of soda. In fact it was he who had discovered twenty years previously that hypo could dissolve silver salts. Herschel, of course, had the fortune to be around just at the time both Daguerre and Fox Talbot were announcing their discoveries. He was evidently very smitten by the Daguerreotype, and conveyed the following news to Fox Talbot: "It is hardly too much to call them miraculous. Certainly they surpass anything I could have conceived as within the bounds of reasonable expectation.... Every gradation of light and shade is given with a softness and fidelity which sets all painting at an immeasurable distance.... If you have a few days at your disposition....come and see!" Fox Talbot, for his part, would not have been very happy about this news, as he was already upset that Daguerre had pipped him to the post in announcing his discovery! It is also to Herschel that we also owe the word "photography", a term which he used in a paper entitled "Note on the art of Photography, or The Application of the Chemical Rays of The picture of Heschel, above, was taken by J M Cameron. HILL and ADAMSON Octavius Hill and Robert Adamson were partners in the earliest days of photography, their earliest known photograph being dated August 1843. Photographers of the day were either artistically inclined or had a strong scientific background, and this partnership was an ideal combination: Adamson was mainly responsible for the more mechanistic aspects of the process (exposure, development and printing), and Hill for the direction, posing and lighting. That, at least, is the way Hill saw it, though it is likely that Adamson, too, had an artistic bent. Restrictions on the Calotype process imposed by Fox Talbot had arrested the development of photography in England, but since the patent did not apply to Scotland these two early photographers were able, in a very short partnership, to produce a considerable number of pictures. At this period, of course, sunlight was necessary, so even the interior photography will have been outside, with suitable props. In order to prevent movement on the part of the sitters all sorts of strategies were needed to keep them still. In "The Bird Cage" for example, the girl in the foreground has her hand firmly on the cage, the girl to the right has her hand fixed on the shoulder of her companion, and her back is against the doorway. The little tell-tale shadows suggests that the girl at the back also had her head cradled - such devices were not uncommon then. One problem that Hill and Adamson failed to resolve was the control of the eye. Because the exposures were so long, it seems that Hill told the sitters to close their eyes rather than blink. So in several of their pictures eyes appear closed. Some of the Hill and Adamson pictures were to be reproduced many years later in Camera Work, a very influential publication produced at the turn of the century. However, Adamson is not credited, and in a lengthy essay on the work of Hill by J. Craig Annan, he is only mentioned in passing. 141 Their Calotypes are now greatly treasured, and many of these are stored in the Victoria and Albert Museum, London. produced. The Hill and Adamson photographs are much valued today, whilst Hill's paintings are ignored and forgotten HILL, David Octavius b. 1802; d. 17 May 1870 David Octavius Hill devoted most of his life to improving the arts in Scotland. He published the first lithographic view of Scotland in "Sketches of Scenery in Perthshire" (1821), and also produced lithographs for "The Works of Robert Burns." He was a portrait painter, and once Secretary of the Scottish Academy of painting, an Academy which he himself had established. HINE, Lewis Wickes b. 26 September 1874; d. 3 November 1940 Lewis Hine was an American sociologist who took up photography in 1905 and used it as a documentary tool, to show the working class conditions of the poor immigrants from Europe. From 1911- 1916 he toured the US as official photographer for the National Labor Committee, where he depicted in a sensitive and heart-rending manner the plight of children working in the mills. He often hid his camera so that he could take authentic photographs, and had first to learn how to get a presentable picture without using flash. In 1843 a major upheaval in the Church of Scotland took place, resulting in the formation of the Free Church of Scotland. Its first meeting took place in May that year, and was considered sufficiently momentous to have the event commemorated in a painting. The task was quite formidable, as there were four hundred and seventy people present, and it was intended that each of these people should be present in the painting. Sketching each person individually would have been a colossal task. A much respected scientist of the day, Sir David Brewster, saw in the newly invented calotype process the solution, and suggested that Hill, who was secretary of the Scottish Academy, go into partnership with a chemist, Robert Adamson. To this end Hill and Adamson took individual portraits of the clerics. The painting, which took twenty-three years to complete, is in the Hall of the Presbytery, Edinburgh, but the photograph is the more remembered. Hill was paid £1500 for the task. The painting is very large, measuring 12ft x 4ft 8ins. Hill and Adamson's pictures are all calotypes. One of them has, on the reverse, "Sol fecit" (the sun made it.) In 1847 Robert Adamson died, aged only 27, and Hill gave up photography and returned to painting. The short partnership is all the more remarkable for the large output; in the four years more than 1500 calotypes had been Hine met with considerable opposition from the employers, who accused him of muck-raking. Sometimes he was banned from the premises, on other occasions the children were hidden from view when he arrived. On occasions Hine even posed as a fire inspector, Bible salesman or insurance agent in order to gain access to the premises! Where he was banned from premises, he would photograph the children arriving at or leaving the factory. Being anxious to provide evidence that could not be discredited, he even measured the children by the buttons on his jacket, having measured their height. In 1916-1917 he travelled some fifty thousand miles in his quest. Hine discovered and exposed some appalling conditions, such as children aged six or seven having to work as many as twelve hours a day. Some of his prints have comments on the back, recording the circumstances. One reads "Sandie Fiefer, 10; South Carolina", another "Mart Payne, picks 20 lbs. cotton a day." "I wanted to show things that had to be corrected", Hine declared. He produced several thousands of pictures. It was not until the 1930s that his work bore fruit, and child labour became controlled. In 1910 he wrote saying: "I am sure I am right in my choice of work. My child labor photos have already set the authorities to work to see if such things can be possible, They try to get around the issue by crying forgery, but that is the value of the dates and the witnesses." Owen Lovejoy, General Secretary of the NCLC and Hine's contracting supervisor, wrote: "The work that you did under my direction was more responsible than any or all other efforts to bring the facts or conditions of child labor employment to public attention." IMPRESSIONISM This movement developed from naturalistic painting, particularly landscape, a central feature of 19th Century art. It carried the realist landscape painting of Courbet and others a stage further, the accent being on colour and light in rapid brush- strokes. The term itself comes from a Monet painting entitled "Impression: Sunrise", painted in 1872, a picture of Le Havre in the mist. A malicious critic, Louis Leroy, dubbed his work "impressionist", using the term in a derogatory way, but others warmed to Monet's style and happily adopted the name; from then onwards Impressionism was a term representing an experience arising from a fleeting impression, rather than laborious detail. Their work is characterised by a variety of brushstrokes, and by high-key colours. Other impressionists in the art world included Degas, Renoir and Pissarro. Sir Ernst Gombrich, the art historian, commenting upon the impressionists, writes: 142 "They discovered that if we look at nature in the open, we do not see individual objects each with its own colour but rather a bright medley of cones which blend in our eye or really in our mind." What brought these artists together was not their strategies or general approach, for they were widely different; what united them was an intense dislike for the art establishment of the time, and repeated rejections by the Salon jury in France. They looked with a measure of contempt at the current establishment; it is said that Sir Joshua Reynolds was nicknamed "Sir Sloshua" by them. Photography also had its impressionists. In May 1874 a group of them in Paris began to exhibit photographs at the studio belonging to Nadar. The group continued in being for the next twelve years, and work was exhibited by, among others, Cezanne and Gaugin. Another photographer who was influenced by the impressionists was George Davidson, who contended that a sharp photograph was not always to be striven for. For one of his photographs, "The Onion field" (1890) he used rough-surfaced paper and a soft-focus technique. The KODAK Story Or part of it, at any rate! Kodak's name will be remembered, not because of any major technical development, but because it was the first company to produce equipment that could be used by anyone. Up till this time would-be photographers virtually had to be chemists as well as artists; they were picture makers in a very real sense! When Kodak cameras appeared on the scene, picture taking came to the fore, and this paved the way for people to concentrate on the image, and leave the preparation and the development processes to others. The genius behind the Kodak camera - and its name - was George Eastman. His first box camera (the Eastman Cossitt) was produced in 1886, but it was too costly. In July 1888 the Kodak camera was exhibited for the first time in Minneapolis, and became an instant success. belongings as the portmanteau" ( a leather trunk for clothes etc., opening into two equal parts). Why the name Kodak? It was short, and easy to pronounce. In the 1920s Eastman wrote: The letter "K" had been a favourite with me - it seems a strong, incisive sort of letter. It became a question of trying out a great number of combinations of letters that made words starting and ending with "K". Other versions soon followed, the No. 2 Kodak camera introducing transparent celluloid film for the first time. The Kodak was relatively small (approximately 6"x3"x3") and though it weighed nearly three pounds, was still much lighter than current cameras. There was no film counter, and the camera was sold with film for 100 exposures (paper-based, incidentally). The lens was wide, with a sixty degree angle of view, thus anything from four feet onwards would be in sharp focus. Because of the wide angle, it was not considered necessary to have a viewfinder. However, the wide angle lens had very poor definition at the edges, so a circular mask was placed in front of the film at the focal plane which was not to everybody's liking. As the advertisements claimed, there were only three simple movements to make: setting the shutter, pressing the exposure button, and winding the film on. And at the end of the film one simply sent the entire camera for processing, and it would be returned with a new film installed. Hence the famous advertising slogan You Press the Button, We do the rest! The Kodak reached Britain fowards the end of 1888, and was immediately acclaimed. The Amateur Photographer review stated: We venture to say that it is, without exception, the most beautiful instrument that has ever been offered for the public in connection with photography. It rapidly became the tourist's camera. From the Photographic News Almanac, 1891: "In my varied wanderings I have met the gentleman with the black leather covered box everywhere.... where the American tourists swarm, the Kodak seems as necessary a part of their The camera was remarkably easy to use. One holiday akrer in 1889 wrote: "We have brought a litle photography machine called the Kodak. It takes a hundred views. All you have to do it just pull a string and press a spring and the business is done." Fool-proof? Well. almost! A photographic dealer recalled how back in 1884 he has sold his first camera: "We sold one for a customer who was departing on a pleasure trip round the world. We loaded it for him and he went away. He returned in about five months and brought in his film to be developed. The result was about twenty five feet of clear film with a very dense, black spot at one end. Our travelled customer had made a hundred exposures without once turning the film!" LANDSCAPE photography From the earliest days of photography, landscape work was popular, even though it often involved considerable trial and inconvenience, particularly when the collodion process was used. An interesting catalogue of landscape photography is to be found in a somewhat poetically-delivered lecture by James Mudd, to the Manchester Photographic Society in 1858: "Landscape photography! How pleasantly the words fall upon the ear of the enthusiastic photographer. What agreeable association are connected with our excursions into the country. How often have we wandered along the rough sea-shore or climbed the breezy hill-side, or descended the shady valley, or toiled along the rock bed of some mountain stream, forgetting, in the excitement of our pursuit, the burdens we carried, or the roughness of the path we trod. What delightful hours we passed in wandering through the quiet ruins of some venerable abbey, impressing, with wondrous truth, upon the delicate tablets we carried, the marvellous beauty of Gothic window, of broken column, and ivy wreathed arch. How pleasant our visits to moss-green old churches and picturesque cottages and stately castles and a thousand pretty nooks, in the shady wood, by the river side, or in the hedgerow, where the wild convolvulus, the bramble and luxuriant fern have arrested us in our wanderings...." Among the leading landscape photographers of this period were Roger Fenton, P.H. Delamotte, and Francis Bedford. visible image, if one were to treat exposed plates with the fumes of heated mercury, an image would start to appear. This was a major breakthrough, because it enabled much shorter exposures to be made. In his record dated 23 September 1840 Talbot wrote about his calotype: "Some very remarkable results were obtained. Half a minute suffices for the Camera, the paper when removed is often perfectly blank but when kept in the dark the picture begins to appear spontaneously, and keeps improving for several minutes, after which it should be washed and fixed with (iodine of potassium)." For latent, then, read "hidden." LARTIGUE, Jacques-Henri b. 13 June 1894; d. 12 September 1986 Lartigue was a French photographer, largely unknown until he was in his seventies, when he was immediately dubbed the "discovery of the century." He started taking pictures at the age of six, and one of his most famous pictures was taken at Grand Prix in 1912 when he was aged eighteen. In this picture he panned the camera so that the car is sharp. The elliptical shape of the wheel and the angle at which the spectators were standing are due to the fact that Lartigue used a focal-plane shutter. He had obviously panned the camera to keep the vehicle sharp; whether the effect caused by the focal-plane shutter was intended or whether it was the result of a lucky accident we are not told! LIGHTING In the early days of photography the only source of light was, of course, the sun, so most photography depended upon long days and good weather. It is said that Rejlander used a cat as a primitive exposure meter: placing the cat where the sitter should be, he judged by looking at its eyes whether it was worth taking any photographs or whether his sitter should go home and wait for better times! The nearer to the birth of photography, the greater the amount of lighting needed, as the first chemical emulsions were very insensitive. Lartigue's interest in photography waned after the first World War, in favour of painting. The first artificial light photography dates back as far as 1839, when L. Ibbetson used oxy-hydrogen light (also known as limelight) when photographing microscopic objects; he made a daguerreotype in five minutes which, he claimed, would have taken twenty-five minutes in normal daylight. LATENT IMAGE, The The earliest exposures were very long indeed, and photographers would peer into the camera to inspect the image as it appeared. At the time it had been assumed that if the image did not appear, no change had occurred. Then Daguerre and Fox Talbot both independently and, it seems, accidentally, discovered that whilst short exposures produced no Other possibilities were explored. Nadar, for example, photographed the sewers in Paris, using batteryoperated lighting. Later arc-lamps were introduced, but it was not until 1877 that the first studio lit by electric light was opened by Van der Weyde, who had a studio in Regent Street. Powered by a gas-driven dynamo, the light was sufficient to permit exposures of some 2 to 3 seconds for a carte-de-visite. Soon a number of studios started using arc lighting. One advert (by Arthur Langton, working in Belgravia, London), boldly proclaims: "My electric light installation is perhaps the more powerful in London. Photographs superior to daylight, Pictures can now be taken in any weather and at any time." More from Arthur Langton's advertisement: "CAUTION Many photographers advertise 'portrits taken by electric light' but 9 out of 10 do not possess an electric light, owing to its costlinss they use an inferior and nasty substitute... a pyrotechnic powder which gives off poisonos fumes." (His spelling, by the way!) In June 1850 an experiment conducted by Fox Talbot, probably using static electricity stored in Leyden jars, was conducted at the Royal Society: a page of The Times was fastened on to a wheel, which then revolved rapidly. Writing about this the following year Fox Talbot stated: "From this experiment the conclusion...is that it is within our power to obtain pictures of all moving objects....providing we have the means of sufficiently illuminating them with a sudden electric flash." The object then had been to arrest fast action. A few years later William Crookes, editor of the Photographic News (October 1859) was responding to a query put to him on how to light some caves: "A...brilliant light...can be obtained by burning....magnesium in oxygen. A piece of magnesium wire held by one end in the hand, may be lighted at the other extremity by holding it to a candle... It then burns away of its own accord evolving a light insupportably brilliant to the unprotected eye...." That same year Professor Robert Bunsen (of Bunsen burner fame) was also advocating the use of 144 magnesium. The first portrait using magnesium was taken by Alfred Brothers of Manchester (22 February 1864); some of the results of his experiments may be found in the Manchester Museum of Science and Technology. It was however very expensive at that time and did not come into general use until there was a dramatic fall in the cost of magnesium a decade later. This, coupled with the introduction of dry plates in the 80s soon led to the introduction of magnesium flashlamps. They all used the same principle: a small amount of this powder would be blown, using a small rubber pump, through a spirit flame, producing a bright flash lasting about 1/15s. It also produced much smoke and ash! Then in the late 1880s it was discovered that magnesium powder, if mixed with an oxidising agent such as potassium chlorate, would ignite with very little persuasion. This led to the introduction of flash powder. It would be spread on a metal dish the flash powder would be set of by percussion - sparks from a flint wheel, electrical fuse or just by applying a taper. However the explosive flashpowder could be quite dangerous if misused. This was not really superseded until the invention of the flashbulb in the late 1920s. Early flash photography was not synchronised. This meant that one had to put a camera on a tripod, open the shutter, trigger the flash, and close the shutter again - a technique known as open flash. Certainly early flash photography could be a hazardous business. It is said, for example, that Riis, working during this period, twice managed to set the places he was photographing on fire! In fact, the "open flash" technique, with flash powder, was still being used by some photographers until the 1950s. This was particularly so when, for example, a large building was being photographed; with someone operating the shutter for multiple exposures, it was possible to use the flash at different places, to provide more even illumination. By varying the amount of grammes of flash-powder, the distance covered could also be varied. To give some idea, using a panchromatic film of about 25ASA and open flash technique, at f8, a measure of 0.1 grammes of flash would permit the flash-subject idstance to be about 8 feet, whilst 2.0 grammes would permit an exposure 30 feet away. The earliest known flash bulb was described in 1883. It consisted of a two pint stoppered bottle which had white paper stuck on it to act as a reflector. To set the flash off, a spiral of ten or so inches of magnesium on a wire skewer was pre-lighted and plunged into the oxygen. It was not to be until 1927 that the simple flash-bulb was to appear, and 1931 when Harold Egerton produced the first electronic flash tube. THE LINKED RING Many artists regard the hanging of their work at the Royal Academy almost as an accolade. So too with photographers. In the 1880s, the exhibitions mounted by the Photographic Society were regarded as the premier event. However, several of its members were becoming increasingly dissatisfied with the Society's emphasis on scientific as opposed to aesthetic matters. As time went on differences between the photographic scientists and photographic artists became greater and more acrimonious, and Henry Peach Robinson was becoming increasingly frustrated by the failure of the Photographic Society to recognise that there was an artistic dimension as well as a scientific one to photography. The Photographic News for 19 August 1892 pinpointed the problem: "If photography is ever to take up its proper position as an art it must detach itself from science and live a separate existence." Commenting upon the proceedings of the Photographic Society, Robinson wrote "For years art has scarcely been mentioned... The feeling that art had nothing to do with the Society became so pronounced two or three years ago that one of the officials expressed his opinion that papers on art may be tolerated if they could be got and there was nothing better to be had...." The circumstances which led to the final breakup between Robinson and the Photographic Society were relatively trivial, but they were the last straw, and led to the resignation of Robinson and George Davidson from the Society. At that time Robinson was a much respected Vice-President of the Society, and had been a member for many years, and his resignation was followed by that of several other distinguished photographers of the time. In May 1892, a few months after the disastrous Council meeting which had culminated in these resignations, Robinson founded the Linked Ring, a brotherhood consisting of a group of photographers based in London, pledged to enhance photography as a fine art. Famous members of this brotherhood (which was by invitation only - one could not apply for it) included Frank Sutcliffe, Frederick Evans, Paul Martin, and Alfred Stieglitz. Though the formation of this group was, as their publicity indicated, "a means of bringing together those who are interested in the development of the highest form of Art of which Photography is capable", it is also very likely that serious photographers were now trying to distance themselves from the growth of photography for all, brought about by the introduction of simple cameras. The idea that anyone could press a button and take a photograph caused the more dedicated to look for new techniques which the "snap photographers" would never aspire to. The brotherhood put on a number of exhibitions and sought to encourage the work of innovative photographers, including work by non-members. Its first major exhibition took place in November 1893, and was known as the Photographic Salon, a title chosen deliberately, in order to associate itself with painting exhibitions, where the same term was used. The exhibition 145 was very well received, and for a number of years - up to the group's demise, it was an important annual event for photographers both in England and abroad. The Link's annual, "Photograms of the year", became world famous. By 1901 some of its members were boldly stating that the Linked Ring had demonstrated that "pictorial photography is able to stand alone and that it has a future entirely apart from that which is purely mechanical." A few years after the formation of this brotherhood, a similar reaction to the photographic establishment was emerging in America, where the Photo-Secession was formed. Many of the more influential members of the Photo-Secession also became members of the Linked Ring, and discontent began to arise because of their domination of the Ring. At the 1908 exhibition of the Salon, photographers discovered that many of the exhibits (over 60%) were by Americans. It was not so much their quantity as their style which angered many British members of the Link. F.J.Mortimer, at the time Editor of the influential magazine "Amateur Photographer", organised at its offices a "Salon des Refusés" of pictures not admitted to the Salon. Meanwhile the British members of the Link, being in the majority, changed the rules for the following year's exhibition, this leading to the resignation from the Brotherhood of several influential Americans including Stieglitz and Clarence White. The success of Mortimer's exhibition, together with internal strife within the Brotherhood after these Americans had resigned, led to the Linked Ring being dissolved. In its place came the London Salon, their first exhibition being held in 1910. The Salon continues to this day, and its original interest, with photography as art, and to "encourage that class of photographic work where there is distinct evidence of artistic feeling and execution" remains the same. However, membership is by invitation only, and this exclusivity has resulted in many exceptional photographers who would sympathise with the aim of the organization ignoring it, considering the movement to have become somewhat pretentious. MICRO-PHOTOGRAPHY This is photography made on a vastly reduced scale, to be observed using a microscope or projected using a "magic lantern." Though George Shadbolt is credited with being the inventor of micro-photography, the first known example of microphotography was by John Benjamin Dancer, in 1839, when he produced photographs 15mm in diameter. microphotographic form, and then were attached to the tails of carrier pigeons. (For further details of this interesting story see HERE). The messages were subsequently enlarged by projection. It is also said that during the Russo-Japanese War of 1904, spies used to smuggle secret reports in micro-photographic form. The term should not be (but often is!) confused with photo-micrography; the micro-photographic process is taken to mean a substantial reduction of the "real thing" either for archival, portability or, as shown above, clandestine purposes. Thomas Sutton , in his 1858 Dictionary of Photography, had little time for this kind of work, which he dismissed as "of little or no practical utility" and "somewhat childish and trivial." However, Sir David Brewster, a prominent physicist and Principal of Edinburgh University, was most enthusiastic about Dancer's work, and predicted that micro-photographs might one day be used to send secret messages in the event of war. In the 1857 edition of the Encyclopaedia Britannica he wrote: "Microscopic copies of despatches and valuable papers and plans might be placed in spaces not larger than a full stop of a small blot of ink." Brewster also took some of Dancer's work on a tour in Europe. It was probably as a result of this tour that several opticians in France began producing micro-photographs. Among these was Rene Dagron, who produced curios, placing microphotographs in penholders, signet rings and other objects. At one stage Dargon employed over a hundred in this flourishing trade. Only a few years later, in the Siege of Paris in 1870, Brewster's prediction came true. Many people were able to escape from Paris by balloon, but because of the prevailing wind a journey to Paris was not possible. To maintain communication with Paris, Dargon and his assistant escaped from the city by balloon, and when they reached the unoccupied zone, he set about preparing a pigeon post service. Messages were printed in 146 MUYBRIDGE, Eadweard b. 9 April 1830; d. 8 May 1904 Edward James Muggeridge was born in Kingston on Thames, and it is said that because this area is associated with the coronation of Saxon kings, he took on a name closely resembling (as he saw it) the Anglo Saxon equivalent. In his early twenties he went to live in America, gaining a reputation for his landscape photographs of the American West. As he used the collodion process, like other travel photographers he would have needed to take with him all the sensitising and processing equipment, as all three processes of sensitisation, exposure and processing needed to be done while the plate was still wet. During the late sixties and early seventies he made some two thousand pictures, exposing negatives size 20x24 inch. Though he is not given due acclaim, many his landscape studies rank with the best. However, Muybridge's main claim to fame (apart from being tried and acquitted for the murder of his wife's lover!) was his exhaustive study of movement. Just about this same time the French physiologist Etienne Marey was studying animal movement, and his studies began to suggest that a horse's movements were very different from what one had imagined. One of the people who became aware of this research was Leland Stanford, a former governor of California, who owned a number of race horses. Stanford was determined to find the truth about this. It is said that he bet a friend that when a horse gallops, at a particular point all four feet are off the ground simultaneously. To prove his case he hired Muybridge to investigate whether the claim was true. By the 1870s lengthy exposures had been reduced to a minimum, and thus it became possible for photography to begin to extend one's vision of reality. It took a little time, however, for Muybridge to perfect a way of photographing which would supply the answer, for the Collodion process was rather slow. Whilst working on this project Muybridge also undertook other assignments, and it was on his return from one of these, we are told, that he became aware that his wife was having an affair with another soldier. In true Wild West style he shot the soldier dead, and was duly imprisoned for murder; however, presumably partly because of his connections, he was acquitted a little later, and was asked to photograph the Panama railroad, some distance away from the scene of the crime. detailed study in this area. It contains more than twenty thousand images. Returning to his movement experiments, a few years later Muybridge was able to photograph a horse galloping, using twenty four cameras, each triggered off by the breaking of a trip-wire on the course. He not only proved Leland right, but also showed that, contrary to what painters had depicted, a horse's feet are not, as hitherto believed, outstretched, as if like a rockinghorse, but bunched together under the belly. This discovery caused considerable controversy, but eventually became more generally accepted. NATURALISTIC Photography In 1889 P.H. Emerson produced a book entitled "Naturalistic Photography for Students of Art." This was at the time pictorialism was in vogue, and Emerson was making the plea that contrived photography, with such manipulation as combination printing, should have no place in photography. Muybridge's studies are very comprehensive, and include some detailed studies of men and women walking, running, jumping, and so on. In 1878 an article in Scientific American published some of Muybridge's sequences, and suggested that readers might like to cut the pictures out and place them in a "zoetrope" so that the illusion of movement might be re-created. Intrigued by this, Muybridge experimented further, and in time invented the zoopraxiscope, an instrument which in turn paved the way for cine photography. This invention was greeted with enormous enthusiasm both in America, whilst in England a demonstration at the Royal Institution in 1882 attracted such people as the Prince of Wales, the Prime Minister (Gladstone), Tennyson, and others. In 1884 the University of Pennsylvania commissioned Muybridge to make a further study of animal and human locomotion. The report, "Animal Locomotion" was published three years later and still ranks as the most In 1900 Muybridge returned to Kingston, where he died a few years later. His zoopraxiscope, together with many of his plates, were bequeathed to the Kingston-upon-Thames Museum, where they are on display. Other plates are in the Royal Photographic Society's collection. Emerson's main claim was that one should treat photography as a legitimate art in its own right, rather than seek to imitate other art forms; imitation was not needed - it could confer its own legitimacy without it. Emerson's feeling was that pictorialism was becoming somewhat bogged down due to sentimentalism and artificiality. At the same time, others were becoming dissatisfied with the fact that the Photographic Society had become too concerned with scientific rather than with artistic aspects of photography. Emerson urged that photographic students should look at nature rather than paintings, that one should look at the range-finder or focusing screen and see what kind of pictures this created. He felt every student should "..try to produce one picture of his own...which shall show the author has something to say and knows how to say it; that is something to have accomplished..." PHOTO-SECESSION movement Towards the end of the century there was a growing dissatisfaction with the photographic establishment in England and in America. In England this led to a mass of resignations from the Photographic Society, and the 147 formation of a group known as the Linked Ring, whilst in America, in 1902, an avant-garde group of photographers, led by Stieglitz, also sought to break away from the orthodox approach to photography, and from what they considered was the stale work of fellowphotographers. The American group came to be known as the Photo-Secession, the name Secession coming from groups of artists in Austria and Germany who had broken away from the academic establishment. Their rejection of establishment photography was aptly summarised in "Photograms of the year" for 1900: "That wealth of trivial detail which was admired in photography's early days and which is still loved by the great general public.... has gone out of fashion with advanced workers on both sides of the Atlantic." "Amateur Photographer", April 10, 1902, published an acount of this movement as follows: Amongst the more advanced pictorial workers in America a definite movement has now taken place; comparable in some respects with the Link Ring movement in this country of ten years or more ago, and at the invitation of the National Arts Club of New York, an Exhibition of Photography is being held by contributors who now for the first time come before the public as an organised body; under the name of the Photo-Secessionists, the main idea of which is to bring together in America sympathetic spirits, whether active photographers or simply those interested in the movement. The Exhibition is in many respects unique, consisting as it does of “ picked ” prints only, and representing only the very best work ever done in America. This American movement is...an attempt... to produce pictures by means of photography. Pictures, that is to say, which shall stand the test of criticism; that one would apply to a picture in any other medium; that shall be satisfactory in composition, colour quality, tone and lighting; that shall have esthetic charm and shall involve some expression of the personal feeling of the photographer. The photographers who profess these high artistic aims and scrupulously live up to their principles and have the ability to practise them, are necessarily few in number, though steadily increasing; nor are they engaged in scholastic discussions as to whether photography can be reckoned among the fine arts, for they leave such theorising to the choppers of academic logic. It is not with phraseology they are concerned, but with facts. ‘ Here is a print,’ they say in effect; ‘ has it any of the qualities that you find in a black and white; does it give you anything of the pleasurable feeling that you experience before a picture in some other medium? If not, we try again; but if, on the other hand, it does, then at least to the extent in which this print has affected you, pray acknowledge that there may be possibility of artistic expression in a pictorial photograph. How far the camera is responsible for the result or how far our own modification of its record, we venture to say is not the question; the sole point, as between you and ourselves, being whether our prints have aesthetic qualities and will stand the test of the kind of criticism that you apply to other pictures." Characteristic of the photography of this new movement was the employment of special printing processes (for example gum bichromate), and of artwork which lessened the detail on the finished print. The movement was not without its critics. Sadakihi Hartmann reacted strongly to the idea of manipulating photographs, and decried those who strove hard to make their pictures seem as if they were not photographs at all. In American Amateur Photographer (1904) he wrote: "We expect an etching to look like an etching, and a lithograph to look like a lithograph, why should not then a photographic print look like a photographic print?" It was not that he objected to retouching or "dodging": "'And what do I call straight photography,' (one might) say, 'can you define it?' Well, that's easy enough. Rely on your camera, on your eye, on your good taste and your knowledge of composition, consider every fluctuation of color, light and shade, study lines and values and space division, patiently wait until the scene or object of your pictured vision reveals itself in its supremest moment of beauty, in short, compose the picture which you intend to take so well that the negative will be absolutely perfect and in need of no... manipulation." From November 1905 the group laid on exhibitions of work at "The Little Galleries of the Photo-Secession" at 291 Fifth Avenue, New York, which came to be known simply as "291." The group lasted about ten years, though their influential and luxuriously printed journal called Camera Work continued publication for some years after. Notable members included Edward Steichen, Clarence White, Gertrude Kasebier, and Alvin Langdon Coburn. Photographic FILM The first photographic film is credited to John Corbutt †, an Englishman working in Philadelphia, who in 1888 coated sheets of celluloid with photographic emulsion. The following year George Eastman produced roll film, designed for a new camera called the Kodak; after exposure the film would be returned still in the camera for processing. Daylight loading film was produced by Eastman Kodak in 1894. The early films were highly inflammable, and gradually became replaced by non inflammable cellulose acetate in the 1930s. Cine projection seemed to be a pretty hazardous business, if the advice to users printed in New Photographer, 2 January 1926 is anything to go by: "Choose a room with more than one exit door if possible, and make sure that the windows can be easily 148 opened in the event of the film charring and beginning to emit smoke, as this smoke is poisonous... Keep a bucket of damp sand close by the projector, and at the first sign of a flare-up throw the machine on the bare floor and tip the sand all over it. If this is done smartly without fuss, and if the people are at once got out of the room and the windows opened, no great harm will accrue beyond the destruction of the film..." † Well, it depends where you look! One book states that the idea of a paper roll film was first conceived by Arthur James Melhuish in 1854. Even more interesting is the story of Revd. Hannibal Goodwin, which clearly suggests that Eastman Kodak had made a claim to inventing film that was unjustified. PICTORIALISM The modern usage of this term may give a misleading picture of the movement as it arose in the second half of the nineteenth century; in any case, like the all-embracing word "art" it is a most elusive, intangible, and highly subjective term. In modern parlance it is sometimes taken to suggest conservatism, and the unwillingness to explore new approaches. In its original meaning anything that put the finished picture first and the subject second was pictorialism. Given such a meaning, pictorialism by no means excluded more modern trends; any photograph that stressed atmosphere or viewpoint rather than the subject would come under this category. By the second half of the nineteenth century the novelty of capturing images was beginning to wear off, and some people were now beginning to question whether the camera, as it was then being used, was in fact too accurate and too detailed in what it recorded. This, coupled with the fact that painting enjoyed a much higher status than this new mechanistic process, caused some photographers to adopt new techniques which, as they saw it, made photography more of an art form. These new techniques came also to be known as High-Art photography. In effect, the term Pictorialism is used to describe photographs in which the actual scene depicted is of less importance than the artistic quality of the image. Pictorialists would be more concerned with the aesthetics and, sometimes, the emotional impact of the image, rather than what actually was in front of their camera. Because pictorialism was seen as artistic photography, one would not be surprised that current styles of art would be reflected in their work; as impressionism was in vogue at the time, many photographs have more than a passing resemblance to paintings in this style. Examples of this approach include combination printing, the use of focus, the manipulation of the negative, and the use of techniques such as gum bichromate, which greatly lessened the detail and produced a more artistic image. Among the major workers who are associated with this approach to photography were Oscar Rejlander, Henry Peach Robinson (who wrote a major book entitled "Pictorial Effect in Photography"), Robert Demachy, and George Davidson. PLATINUM printing This process dates from 1873, when it was introduced by William Willis. Plain paper with sensitive iron salts (no silver) was exposed in contact with a negative. The print would then be developed in a potassium oxalate solution. The process produced an image with beautifully rich black tones, and a tremendous tonal range, that makes platinum prints stand out. It was also, unlike other processes, permanent. Amongst those who used this medium were Peter Henry Emerson, Clarence White , Frederick Evans, and Gertrude Kasebier. One of the reasons why this and the gum-bichromate process became more popular amongst serious photographers was that these were ways of distancing themselves from the snapshooters which began to proliferate as a result of the introduction of the first Kodak cameras and film; both processes required skills above the level of the casual amateur photographer. Its use declined after the first world war because of the rising cost of platinum, when palladium largely replaced it. PORTRAITURE Throughout history people have sought to produce images either of themselves or of others. The problem is that the skills required to make portraits are in short supply, and therefore expensive. Until the eighteenth century, therefore, portraits were generally regarded as the privilege of the wealthy. In any case, artists are able, through this medium, not only to depict what they see, but what they believe or prefer to portray. There are several instances in which a famous personality has been painted on numerous occasions, and have such striking differences that it is difficult to know what the sitter really looked like! The eighteenth century saw a demand for portraits which were less expensive, and this resulted in two developments. One was the use of miniature portraits, which were relatively much less expensive; the other was the popularity of profile pictures, usually traces from the shadow cast by a lamp, sometimes cut freehand from paper. This technique was named after Etienne de Silhouette (1709-1767), who made profiles, and such silhouettes, often embellished with gold, became very popular. The invention of photography marked a watershed as far as portraiture was concerned, and it is not difficult to understand why photography, from the earliest days, had such an instant appeal both in America and in Europe, particularly in this area. Portraiture, once only for the well-to-do, was now available to all, as a natural leveller. There was a lot of money to be made out of the practice. One of the earliest photographers, Richard Beard, was said to have earned forty thousand 149 pounds in one year (a large sum today - a fortune then!) head, he explains in a voice and with a look suggestive of lead and gunpowder: 'Dare to move a muscle and I'll blow your brains out....'" However, this profession could also be precarious. Beard himself became bankrupt in 1847, and Scott Archer, who invented the Wet Collodion process, died penniless. Sutcliffe, the brilliant photographer of Whitby, failed in Tunbridge Wells, and had to sell out and return to Whitby. Consequently some photographers diversified. Thomson in addition to being a photographer, was a tobacconist, and like others, would offer a photograph and a cigar for six pence (2.5p) Others combined photography with more traditional art. The portrait, though much sought after, was often an event which one had good cause to remember: As the process was only sensitive to blue or white, one had to dress in appropriate colours. Henry Peach Robinson used to provide very specific hints; the portrait could only be taken if the weather was suitable; clients would often have to climb a number of stairs, as most of the studios were located on the top of a building; there were various methods of keeping a sitter still, a popular one being a metal clamp (hidden from the camera) behind the sitter's head. (This was not new to photography, one must add - it was quite commonly used on conventional portraiture). One sitter recalled the ordeal: "(He sat) for eight minutes, with strong sunlight shining on his face and tears trickling down his cheeks while...the operator promenaded the room with watch in hand, calling out the time every five seconds, until the fountains of his eyes were dry." Another, advertising photography "without pain" proposed to use gas on his sitters, and once they were out for the count, he would take the picture. Yet another suggested "A good dose of laudanum (opium) will effectively prevent the sitters from being conscious of themselves, of the camera, or anything else. They become most delightfully tractable, and you can do anything with them under such circumstances....." Full length portraits often reveal how carefully one posed people in order to keep them still and yet provide a natural posture. An interesting photograph is "The Bird Cage" by Hill and Adamson (a section of which is shown on the above); one should note how carefully the hands are placed in this picture, and note also the tell-tale shadow behind the head of the lady on the right, which suggests that there was some device to keep her head still during exposure. One problem which Hill and Adamson were not able to resolve was eye control. Exposures were very long indeed, and it is likely that Hill (the artist of the two) advised sitters to close their eyes unless they were very good at keeping their eyes open without blinking. Here is one way to solve the problem! One of Fox Talbot's pictures, of his wife and daughters: they are facing the other way, and we only see their hats! (Picture dated 19th April 1842) Trying to keep a sitter still for this long process must sometimes have been quite a feat. The most extreme form of persuasion comes from an article in the American Journal of Photography, 1861, where we read of one operator who had tried all sorts of means of persuasion, "...when it occurred to him that the strongest of all human motives is fear. As soon as he had completed his adjustments, he suddenly draws a revolver, and levelling it at the sitter's Though there are many examples of work before the invention of Collodion, it was the discovery of this process which triggered off the enormous boom in portraiture. In April 1857 Lady Elizabeth Eastlake, whose husband had been the first President of the Photographic Society, wrote: "Who can number the legion of petty dabblers, who display their trays of specimens along every great thoroughfare in London, executing for our lowest servants, for one shilling, that which no money would have commanded... twenty years ago? Not that photographers flock especially to the metropolis; they are wanted everywhere and found everywhere. The large provincial cities abound with the sun's votaries, the smallest town is not without them; and if there be a village so poor and remote as not to maintain a regular establishment, a visit from a photographic travelling man gives it the advantages which the rest of the world are enjoying. Thus, where not half a generation ago the existence of such a vocation was not dreamt of, tens of thousands.... are now following a new business, practising a new pleasure, speaking in a new language, and bound together by a new sympathy." It has to be said that this was a period in which portraiture was perhaps more characterised for the quantity of production, rather than by its quality. To some extent the early photographers may be exonerated, because of the technical aspects which so dominated the process. Nevertheless, many of the Carte-de- 150 visite portraits were verging on the banal, their authors being apparently more concerned with making a quick profit than to "portray" the sitter. The lighting for many of these was uninteresting, the setting often so stereotyped that one can almost date the photographs by the props! Bluntly, many images show evidence of very fast impersonal photography where the practitioner was out to make a quick kill and had little time or interest for the sitter as a person. The length of exposure, coupled with a conveyor-belt mentality by some photographers, is the main reason why so many pictures, particularly daguerreotypes, appear so impersonal. Sitters would either stare into the camera or would look into the distance, as Lewis Carroll put it in Hiawatha's photography: "With a look of pensive meaning As of ducks that die in tempests" The "style" being used was not only determined by financial considerations but to some extent by the demands of the sitter; it was fashionable to have pictures which took people out of the real, possibly harsh world and presented them as more well-to-do than in real life, hence the use of standard props which provided such an image. Not all photographers of the period may have welcomed this, but the customer has always to be right; Robinson is said to have commented upon the many people who buy clothes specially for the occasion, and to have said "How am I to get a likeness of a person who does not look like herself?" Many of the images are full-length photographs, which show more of the props and mock glamour than the faces being portrayed, and given the fact that a straight photograph (unlike a portrait) can be cruel, such an arrangement may have satisfied the needs of both photographer and sitter! Nevertheless, there are some remarkable exceptions to this rather dismal trend, where there is evidence that the photographer went to great lengths to portray the sitter as would a painter, by making them feel at ease, by producing close-ups of the face that revealed their personality, by using more adventurous lighting, and by discarding trite backgrounds. Some interesting advice to patrons was provided by Edward Wilson, especially on what to wear. For such photographers, the motive was not profit but quality. Among such workers are Hill and Adamson, Julia Margaret Cameron, Lewis Carroll and, sometime later, Alvin Langdon Coburn. Another photographer who used portraiture, but for medical reasons, was Hugh Welch Diamond. PRE-RAPHAELITES The Pre-Raphaelite brotherhood was founded in 1848, and consisted of a group of mainly British artists, all in their twenties, who rejected the neoclassical style which at that time was in vogue, wishing to return to what they felt to be purer Early Renaissance art. Their name comes from the fact that they believed that Raphael had introduced the art they so disliked. Though the movement lasted only ten years or so, the impact they had upon art in Britain at the time was considerable. The movement had in the main three phases: realist - where the emphasis was upon historical and religious paintings (eg Rossetti, Hunt) "truth to nature" - where the stress was upon contemporary scenes, almost of surreal detail; a fascination for the Middle Ages, leading to painting of Arturian legend, and mediaeval themes and styles. They tended to look to the past for their inspiration, and thus their pictures had religious, mythological or historical bases, particularly mediaeval themes. Their message appeared to be that truth was ugly, that to beautify it to make "high art" dress people up contrive the situations. Initially they all exhibited pictures anonymously, all using the same initials PRB. When a few years later the names of the painters became known, they were quite harshly taken to task by Charles Dickens, Amongst their number are names such as Holman Hunt - who painted "The Light of the World" (1853), and Dante Rossetti. John Ruskin actively promoted this trend, and though the group disbanded in 1855, its ideas continued for quite some time. Among those who one might suggest were influenced by the Pre- Raphaelite movement were Lewis Carroll, Julia Margaret Cameron, Henry Peach Robinson and Francis Bedford. It would be wrong to imagine that a school of Pre-Raphaelite photography existed, but rather that a number of photographers shared some of the sentiments typical of those who were in the Brotherhood. TONING, Print Toning was a chemical process which changed the colour of a photograph. It had a further benefit in that a toned image would be far more permanent. Gold toning came into use in the 1850s, using gold chloride. The tone of the prints varied considerably, as the toning depended upon such factors as the density of the negative, the light, and even the way the paper had been sized. (For example, one finds that prints made in England seem warmer than those made in France, which was due to the fact that paper sizing in England was with gelatin). SALTED PAPER Until 1850, the earliest prints were salt-paper ones. They were made by coating sheets of paper with salt dissolved in water, and then sensitising the paper. Salted papers were not subjected to development. They were printed out; that is to say they were contact prints, placed in a frame with the negative, but left to print out in the sun, a process that would take approximately thirty minutes. It would then be fixed in the normal way. Because the paper had been sensitised in this manner, the image 151 was in the paper, rather than on it. The texture of the paper, then, also appeared on the image, and this caused a loss of definition. Some actually preferred this, and were not taken by the glossy appearance of the albumen paper which began to supersede it (see for example Shadbolt), preferring the matte form of salted-paper. SEPARATION negatives It was James Clerk Maxwell who first showed that by taking three separate pictures, each through a filter (red, blue and green) and by superimposing the lantern slides (again with the appropriate filter in each projector), colours could be re- created. The three negatives produced in this way are called colour separation negatives, because the visible spectrum has been separated into three parts. Early attempts to reproduce colour began at the turn of the century, but were out of the reach of all but the more dedicated and wealthy photographer. Initially the subjects were still-life ones (obviously the three images had to be exactly the same), though cameras were then produced which exposed three pictures simultaneously. SOCIAL REFORM, Photography Very early in the days of photography this medium began to be used as a means of promoting social reform. Richard Beard photographed street scenes to illustrate a major project on the poor in London; unfortunately these are no longer in existence. In a similar vein John Thomson illustrated "Street Life in London" (1877); other pioneers were Thomas Annan, a Scot, who portrayed the slums of Glasgow, and Paul Martin. Eduard Steichen (he later changed his name to Edward) was born in Luxembourg, and when he was still a baby the family emigrated to America. He studied painting in Paris, and had soon gained a reputation for his work in photography. In 1900 Clarence White saw his photographs and lent some encouragement to him. White also wrote to Stieglitz, who bought some of Steichen's photographs. In 1901 Steichen was elected to the Linked Ring, and the following year he became a founder of the PhotoSecession, and designed the cover for Camera Work. Until the first world war Steichen's work consisted largely of photographs in a post-impressionist style. Later he was to burn all his paintings and concentrate totally on photography. Initially his photographs show an impressionist influence, with soft focus. He later turned his style to "straight" photography. In a somewhat whimsical mood Steichen once wrote: "Some day there may be... machinery that needs but to be wound up and sent roaming o'er hill and dale, through fields and meadows, by babbling brooks and shady woods - in short, a machine that will discriminately select its subject and, by means of a skillful arrangement of springs and screws, compose its motif, expose the plate, develop, print, and even mount and frame the result of its excursion, so that there will be nothing for us to do but to send it to the Royal Photographic Society's exhibition and gratefully to receive the 'Royal Medal'." In 1613 the Jesuit Francois d'Aguillion (1567-1617), in his treatise, coined the word "stéréoscopique" The first practical steps to demonstrate the theory by constructing equipment for the purpose did not take place until the 1800s. Though most associate Brewster with the invention, it was Sir Charles Wheatstone who, in June 1838, gave an address to the Royal Scottish Society of Arts on the phenomena of binocular vision. In describing the equipment, he said: "I...propose that it be called a Stereoscope, to indicate its property of representing solid figures." Wheatstone's actual stereoscope is preserved at the Science Museum in London. Eleven years were to elapse before Sir David Brewster described a binocular camera, and the first stereoscopic photographs began to be produced. Early workers in this field include Fenton, who took photographs in Russia, when he visited there in 1852, and Jules Duboscq, who made stereoscopes and stereoscopic daguerreotypes. Duboscq in turn caused Antoine Claudet to become interested in stereoscopy; indeed, it was Claudet who patented stereoscopes in 1853. Jacob Riis, a journalist, photographed the awful conditions in the slums of New York, whilst Lewis Hine, towards the end of the century, was involved in a campaign to change child-labour laws in the USA. STEICHEN, Eduard Jean b. 27 March 1879; d. 25 March 1973 Stereoscopic, or 3D photography, works because it is able to recreate the illusion of depth. Human eyes are set about two-and-a-half inches apart, so each eye sees an image slightly differently. If one takes two separate photographs that same distance apart, with a suitable viewer it is possible to recreate that illusion of depth. It comes as a surprise to many to learn that the idea of stereoscopy actually preceded photography. Binocular drawings were made by Giovanni Battista della Porta (1538-1615), whilst about the same period Jacopo Chimenti da Empoli (1554-1640) produced drawings side by side which clearly indicated his understanding of binocular vision. STEREOSCOPIC photography The stereoscope took off in a big way when Queen Victoria and Prince Albert 152 observed one at the exhibition at the Crystal Palace, and Brewster presented her with a stereoscope made by Duboscq. This signalled the beginning of a huge trade in stereoscopes and images; it is estimated that by the mid eighteenfifties over a million homes owned one. One of the most successful salesmen of stereoscopic cards was George Nottage, later Lord Mayor of London, his catalogues listing over one hundred thousand views. The most common process for making stereoscopic cards was the Albumen one, daguerreotype images being very rare. A variety of viewers became available, from the simple Holmes viewer, shown here, to cabinet-type viewers which could store fifty or so positives. A different way to view images is the anaglyph process, which was developed by Ducos Du Hauron, and was a method of printing two images on to one sheet. The process is still quite popular today. The London Stereoscopic and Photographic Company came into being in 1850 and continued for some seventy years. Their output was collossal; they listed over a hundred thousand stereo photographs in their 1858 catalogue. In general they tended to be views, plus some portraits of comic scenes. The Stereoscopic Society was founded in 1893, and is one of two societies operating in Britain which continue to promote this form of photography. It is still in existence, and details can be found here. Though there exist (quite expensive) stereo cameras in the second-hand market, if one is photographing a still object a single camera is all that is needed. An article in Amateur Photographer, dated November 27, 1902, had a lengthy article, together with examples of the picture produced. Those able to uncross their eyes so that the two pictures fuse can see the stereo effect. STIEGLITZ, ALFRED b. January 1, 1864; d. July 13, 1946 Stieglitz, an American photographer, probably did more than any other individual to promote photography as an art at the same level as other arts, and has been dubbed the "patron saint of straight photography." It is said that at the age of eleven he had begun to take an interest in photography, and learned by observing a local portrait photographer work in the darkroom. His blunt nature often came over: on one occasion he observed the photographer re-touching a plate, and on enquiry, was told that this made the subject look more natural - to which he replied "I wouldn't do that if I were you." He studied mechanical engineering and photography at the Polytechnic of Berlin. In 1883 Stieglitz saw a camera in a shop window in Berlin, bought it, and photography in earnest began. Many years later he wrote "I bought it and carried it to my room and began to fool around with it. It fascinated me, first as a passion, then as an obsession." From 1892 he was becoming famous for his photographs of everyday life in New York and Paris. There is a tremendous atmospheric quality in many of his outdoor scenes. your subject, regardless of figures, and carefully study the lines and lighting. After having determined upon these watch the passing figures and await the moment in which everything is in balance; that is, satisfied your eye. This often means hours of patient waiting. My picture, "Fifth Avenue, Winter" is the result of a three hours' stand during a fierce snow-storm on February 22nd 1893, awaiting the proper moment. My patience was duly rewarded. Of course, the result contained an element of chance, as I might have stood there for hours without succeeding in getting the desired pictures." In 1902 he became one of the founders of the Photo-Secession, a group of talented avant-garde artists. In 1905 he also founded and directed the Photo-Secession Gallery in 291 Fifth Avenue, New York, a gallery which came to be known as the "291", and which exhibited not only the work of contemporary photographers, but also works of Picasso, Rodin, Matisse and Toulouse-Lautrec. Speaking in New York, in 1902, Stieglitz said "The result is the only fair basis for judgment. It is justifiable to use any means upon a negative or paper to attain the desired end." In the 1890s Stieglitz took a pioneer step in moving towards a hand-held camera. In "The Hand Camera - its present importance" (1897) he wrote: Stieglitz, committed to the idea of photography as art, often found this challenged. "The writer does not approve of complicated mechanisms, as they are sure to get out of order at important moments, thus causing considerable unnecessary swearing, and often the loss of a precious opportunity. My own camera is of the simplest pattern and has never left me in the lurch, although it has had some very tough handling... A shutter working at a speed of onefourth to one-twenty-fifth of a second will answer all purposes. A little blur in a moving subject will often aid to giving the impression of action and motion. "Artists who saw my early photographs began to tell me that they envied me; that my photographs were superior to their paintngs, but that unfortunately photography was not an art.... I could not understand why the artists should envy me for my work, yet, in the same breath, decry it because it was machine-made their...'art' painting - because handmade, being considered necessarily superior....There I started my fight...for the recongition of photography as a new medium of expressions, to be respected in its own right, on the same basis as any other art form." In order to obtain pictures by means of the hand camera it is well to choose In 1903 Stieglitz launched, edited and published Camera Work - a magazine 153 which became world famous and continued publication for a number of years. Amateur Photographer was most enthusiastic, and on its first edition of 1903 wrote: "For Camera Work as a whole we have no words of praise too high, it stands alone; and of Mr. Alfred Stieglitz American photographers may well be proud. It is difficult to estimate how much he has done for the good of photography, working for years against opposition and without sympathy, and it is to his extraordinary capacity for work, his masterful independence which compels conviction, and his self-sacrificing devotion that we owe the beautiful work before us." In 1907, it was during a trip to Europe that one of his most well-known photographs was taken It is called "The Steerage": "There were men and women and children on the lower deck of the steerage.... I longed to escape from my surroundings and join them.... A round straw hat, the funnel leaning left, the stairway leaning right.... round shapes of iron machinery... I saw a picture of shapes and underlying that, the feeling I had about life..." Stieglitz did much to promote photography, and to get it talked about. There were two stages in his life: at first he produced somewhat romanticised pictures of an Impressionistic style, then later moving over to realism of a high order. He also had pronounced views about the current controversy over amateur photographers and the professional. Not the easiest of people to get on with, his leadership was little short of dictatorial and he was an insufferable egocentric windbag, but he made a distinct and influential contribution to the development of new styles of photography. He was a visionary of the highest order. His own photography alone makes him stand out as one of the greatest of photographers; his influence over photography has been enormous. STRAND, Paul b. 16 October 1890; d. 31 March 1976 Paul Strand was an American who was taught photography by one of his school teachers, Lewis Hine, and who became a successful photographer. He was greatly influenced by the Photo-Secession group, and made some superb abstract close-up pictures. Initially he did some experimental work in the medium, but then moved over to what we know as straight photography - work which relied totally upon subject, viewpoint and choice of lighting, rather than upon any manipulation at either the negative or the printing stage. Some of his work appeared in the last two editions of Camera Work (1916-17). In what turned out to be the last edition, Alfred Stieglitz described Strand's work: Strand's images were contact prints, many from 10" by 8" negatives. The SUBTRACTIVE process There are two ways of producing a colour, the additive process and the subtractive one. In the subtractive process a colour is produced by subtracting colours from white light. So to produce yellow, for example, blue is subtracted from white. The three filters associated with this process are blue-green (called cyan) which is white minus red, magenta, which is white minus green, and yellow, which is white minus blue. This forms the basis of the current colour photographic systems. "His work is rooted in the best tradition of photography. His vision is potential. His work is pure. It is direct. It does not rely upon tricks of process. In whatever he does there is applied intelligence. In the history of photography there are but few photographers who, from the point of view of expression, have really done much work of any importance. And by importance we mean work that has some relatively lasting quality, that element which gives all art its real significance... The work is brutally direct. Devoid of any flim-flams; devoid of trickery and any 'ism', devoid of any attempt to mystify an ignorant public...." In this edition are "Blind" and "The Fence." Both are well- known, the latter clearly ignoring the conventional rules of perspective. Strand himself wrote: "Objectivity is of the very essence of photography, its contribution and at the same time its limitation..." "Honesty no less than intensity of vision is the prerequisite of a living expression. This means a real respect for the thing in front of... the photographer... this is accomplished without tricks of process or manipulation through the use of straight photographic methods..." 154 TALBOT, William Henry Fox b. 11 February 1800; d. 17 September 1877 His signature is Henry Talbot, and though he is said to have disliked being called Fox Talbot, that name has stuck. Though Fox Talbot was not the first to produce photographs, he made a major contribution to the photographic process as we know it today. Talbot studied the classics and mathematics at Cambridge, was elected a Fellow of the Royal Astronomical Society in 1822, and a Fellow of the Royal Society in 1832. He was also an MP, Biblical scholar, a Botanist and Assyriologist, making a contribution to the deciphering of cuneiform inscriptions brought to England from Nineveh. Though some of his pictures show a measure of artistic taste, it was his inability to draw which caused him to experiment with a mechanical method of capturing and retaining an image. Talbot attempted to draw with the aid of both a camera obscura and a camera lucida when producing his sketches, one of which was Villa Melzi. Later he wrote: "(In) October, 1833, I was amusing myself on the lovely shores of the Lake of Como in Italy, taking sketches with a Camera Lucida, or rather, I should say, attempting to make them; but with the smallest possible amount of success... After various fruitless attempts I laid aside the instrument and came to the conclusion that its use required a previous knowledge of drawing which unfortunately I did not possess. I then thought of trying again a method which I had tried many years before. This method was to take a Camera Obscura and to throw the image of the objects on a piece of paper in its focus - fairy pictures, creations of a moment, and destined as rapidly to fade away... It was during these thoughts that the idea occurred to me... how charming it would be if it were possible to cause these natural images to imprint themselves durably and remain fixed on the paper!" The earliest surviving paper negative is of the now famous Oriel window in the South Gallery at Lacock Abbey, Wiltshire, where he lived. It is dated August 1835. Talbot's comments read "When first made, the squares of glass about 200 in number could be counted, with help of a lens." Talbot described how he took his pictures: "Not having with me... a camera obscura of any considerable size, I constructed one out of a large box, the image being thrown upon one end of it by a good object-glass fixed at the opposite end. The apparatus being armed with a sensitive paper, was taken out in a summar afternoon, and placed about one hundred yards from a building favourably illuminated by the sun. An or so afterwards I opened the box and I found depicted upon the paper a very distinct representation of the building, with the exception of those parts of it which lay in the shade. A little experience in this branch of the art showed me that with a smaller camera obscura the effect would be produced in a smaller time. Accordingly I had several small boxes made, in which I fixed lenses of shorter focus, and with these I obtained very perfect, but extremely small pictures..." These "little boxes", measuring two or three inches, were named "mousetraps" by the family at Lacock, because of the various places they were to be found. January 1839 was a busy month as far as announcements of discoveries were concerned. On 7 January Daguerre announced the development of his process. A few days later Talbot wrote to Arago, who had promoted Daguerre's invention, suggesting that it was he, not Daguerre, who had invented the photographic process. (At that time he was unaware that the process was entirely different). One of Arago's fellow-scientists replied that Daguerre had, in fact, devised a number of processes over fourteen years. Doubtless annoyed that Daguerre had been put in the lime-light he felt he himself deserved, Talbot began to publicise his own process. On 25 January 1839 he announced the discovery at the Royal Institution of a method of "photogenic drawing." At the time the sensitivity of the process was extremely poor. Then, in September 1840 Fox Talbot discovered the phenomenon of the latent image. It is said that this was a chance discovery, when he attempted to re-sensitise some paper which had failed to work in previous experiments; as the chemical was applied, an image, previously invisible, began to appear. This was a major breakthrough which led to drastically lowered exposure times - from one hour or so to 1-3 minutes. Talbot he called the improved version the calotype (from the Greek "Kalos", meaning beautiful) and on 31 January he gave a paper to the Royal Society of London. The paper was entitled "Some account of the Art of Photogenic drawing, or the process by which natural objects may be made to delineate themselves without the aid of the artist's pencil." Talbot patented his invention on 8 February 1841, an act which considerably arrested the development of photography at the time. The patent (a separate one being taken out for France) applied to England and Wales. Talbot chose not to extend his patent to Scotland, and this paved the way for some outstanding photographs to be produced in Edinburgh by Hill and Adamson. In 1844 Talbot began issuing a book entitled "The Pencil of Nature", the first commercial book to be illustrated with actual photographs.* In order to produce these prints, he helped his former valet, Nicolaas Henneman to set up the Reading Establishment, a photographic processing studio within relatively easy reach of both London and Lacock. This however lasted only four years, as it was not a financial success. Talbot's process in general never reached the popularity of the daguerreotype process, partly 155 because the latter produced such amazing detail, but partly because Talbot asked so much for the rights to use his process. A writer of the time, Henry Snelling, commented: than is commonly supposed. (See Talbot and patents.) "He is a man of some wealth, I believe, but he demands so high a price for a single right.... that none can be found who have the temerity to purchase." "I do not profess to have perfected an art but to have commenced one, the limits of which it is not possible at present exactly to ascertain. I only claim to have based this art on a secure foundation." Consequently calotypes never flourished as they might have, and the fault must lie largely with him. The newly formed Calotype club sought unsuccessfully to persuade Talbot to relax his restrictions in order to encourage the growth of photography. It is claimed that Talbot, somewhat put out by the fact that Daguerre had received many honours whilst he had been given none, was reacting accordingly. Sadly Talbot's name was somewhat tarnished by his series of attempts to enforce his patent. A claim in 1854 that the Collodion process was also covered by his calotype patent. was lost in court, and from then onwards, knowing that the faster and better collodion process was free for all to use, there were no further restrictions and photography began to take off in a big way. Having said this, there exists some evidence that there had been a concerted attempt to discredit Talbot in order to overturn the patent. Talbot increasingly viewed the defence of his calotype patent as a defence of Henneman, who had invested heavily in setting up the Reading Establishment . Talbot was enormously loyal to Henneman, and concerned about profit being made at his expense It is possible, therefore, that history has been a little too harsh on Fox Talbot. He too had spent a considerable amount of money developing his invention, and it has been suggested that his enforcement of patents was more due to his careful upbringing as far as finances were concerned than his desire to make a fortune. Other documents, particularly relating to the early days of the Photographic Society, reveal him to be far more magnanimous and generous Talbot summarised his achievement thus: The Royal Photographic Society has two complete sets of the limited edition of "Pencil of Nature", together with many of Fox Talbot's letters, books and documents. The TINTYPE process First, see Ambrotype. The tintype, also known as a ferrotype, is a variation on this, but produced on metallic sheet (not, actually, tin) instead of glass. The plate was coated with collodion and sensitized just before use, as in the wet plate process. It was introduced by Adolphe Alexandre Martin in 1853**, and became instantly popular, particularly in the United States, though it was also widely used by street photographers in Great Britain. That this process appealed to street photographers was not surprising: the process was simple enough to enable one to set up business without much capital. It was much faster than other processes of the time: first, the base did not need drying, and secondly, no negative was needed, so it was a onestage process. The material could easily be cut up and therefore fitted into lockets, brooches, etc. The most common size was about the same as the carte-de-visite, 2 1/4'' x 3 1/2'', but both larger and smaller ferrotypes were made. The smallest were "Little Gem" tintypes, about the size of a postage-stamp, made simultaneously on a single plate in a camera with 12 or 16 lenses. Compared with other processes the tintype tones seem uninteresting. They were often made by unskilled photographers, and their quality was very variable. They do have some significance, however, in that they made photography available to working classes, not just to the more well-to-do. Whereas up till then the taking of a portrait had been more of a special "event" from the introduction of tintypes, we see more relaxed, spontaneous poses. Cheap to produce, a typical price for a tintype was 6d (2 1/2p) and 1 shilling (5p). being more robust than ambrotypes it could be carried about, sent in the post, or mounted in an album. 156 Some tintypes that remain are somewhat poignant. The one shown here is of a child who has died. If this seems bizarre, it would seem to have been quite a practice in the last century. In fact, the original name for Tintype was "Melainotype." It is perhaps worth adding that there was no tin in them. Some have suggested that the name after the tin shears used to separate the images from the whole plate, others that it was just a way of saying "cheap metal" (ie non-silver). The print would come out laterally reversed (as one sees oneself in a mirror); either people did not worry about this, or just possibly they did not discover it until after the photographer had disappeared!*** Being quite rugged, tintypes could be sent by post, and many astute tintypists did quite a trade in America during the Civil War, visiting the encampments. Later, some even had their shop on river-boats. Tintypes were eventually superseded by gelatin emulsion dry plates in the 1880s, though street photographers in various parts of the world continued with this process until the 1950s; the writer well remembers being photographed by one of these street photographers in Argentina, when he was a boy. Eventually, of course, 35mm and Polaroid photography were to replace these entirely. ** Professor Hamilton L. Smith was the first to make ferrotypes in the Unites States, and he and Victor Moreau Griswold introduced the process to the photographic industry. TRAVEL photography To appreciate the impact that photography made upon Victorian life one needs to remind oneself what little opportunity there was for any but the rich to visit other lands. Consequently, until photography was used, the majority of people would have needed to rely on the accuracy and integrity of explorers. Photography at last made it possible for a much larger proportion of people to see for themselves pictures of exotic lands afar and thus at least enjoy a vicarious experience; it also gave them an opportunity to realise how incorrect some reports had been. The invention of photography also coincided with the development of steam boats and the railways. Claudet waxed lyrical on the new horizons opened up as a result of the work of travel photographers: "By our fireside we have the advantage of examining (the pictures) without being exposed to the fatigue...and risks of the daring and enterprising artists who, for our gratification and instruction, have traversed lands and seas, crossed rivers and valleys, ascended rocks and mountains with their heavy photographic baggage..." One needs perhaps to appreciate how hard life as a travel photographer could be. Because the processing had to be done quickly after exposure, photographers on location needed to take away with them an enormous amount of equipment - boxes of plates, bottles galore, and of course the camera. These were the days before enlargers had been introduced, so large cameras, some producing plates size 12" by 16" (30cm by 40cm) had to be transported - and they were pretty heavy. The following, a report on the exploration of the Grand Canyon in 1871, gives us a flavour: "The camera in its strong box was a heavy load to carry up the rocks, but it was nothing to the chemical and plate- holder box, which in turn was a featherweight compared with the imitation hand organ which served for a darkroom...." Some did the journey, returning without any pictures at all... "The silver bath had got out of order, and the horse bearing the camera fell off a cliff and landed on top of the camera..." In this connection, though he was a war photographer rather than a travel one, it is worth seeing what Roger Fenton had to cope with when he worked at his photographs on location. One of the very earliest pioneers was the Rev. George Bridges, who had been taught photography by one of Fox Talbot's assistants, and by 1852 he had produced some 1,500 paper negatives of scenes in the Mediterranean and Egypt. The major pioneers in travel photography include Maxime Du Camp, Francis Frith, and Francis Bedford, all of whom took photographs in the Middle East. In America John C. Fremont was the first explorer to attempt to make a photographic document of his travels, but on his first attempt in 1842 he failed to get any photographic results. A Baltimore daguerreotypist, Solomon Nunes Carvalho, was also a pioneer. Interestingly, calotypes continued to be used by some travel photographers, because they were less of an ordeal than collodion. After all, calotypes, for all their imperfections, permitted the photographer to prepare paper negatives at home, expose on location, and then develop upon returning home. Diamond, for example, used the calotype process for some of his travel photographs, though once at home he reverted to collodion for portraiture and for his medical photography. Other travel photographers include Samuel Bourne, who took particularly striking pictures of Indian architecture, often under very trying conditions, whilst Charles Clifford took some excellent pictures of Spanish architecture. Another photographer who, though sporting an unforgettable 157 name, is almost unknown, is Linnaeus Tripe, who made many interesting photographs of Burma. Also worthy of mention are William Young who photographed in East Africa, Herbert Ponting who covered Captain Scott's expedition, and Lord Carnarvon, who photographed the tomb of Tutankhamen. VORTOGRAPHS and VORTICISM With its roots in Futurism and Cubism, Vorticism was a movement introduced by the painter and writer Wynham Lewis when he published "Blast: Review of the Great English Vortex." In this the traditional values were ridiculed, and modern technology exalted. This movement was championed by the poet Ezra Pound, and made popular by Alvin Langdon Coburn, who was one of its leading exponents. Like all movements, a concise definition can be misleading, but one of the aims of the Vorticist photographer was to mirror the complexity of industrialised civilisation. The roots of this were in Cubism. Another exponent of this relatively short-lived movement (three years or so) was Malcolm Arbuthnot, a regular contributor to the Amateur Photographer in the early part of the 20th century. WAR, Photography An early example of documentary photography is the record of war, which brought home to people some grim realities which shattered their fantasies. Photographers of note include James Robertson, who covered the siege of Sebastopol, and Roger Fenton, who covered the Crimean war, though the latter is more adequately described as a public relations exercise for the government of the day. Even as far back as 1839 the use of photography in this area was being talked about. Amongst the many uses of the Daguerreotype, Joseph Louis Gay-Lussac argued, was its capacity to render a landscape precisely. He cited one particular kind of landscape to make his point: ... as three or four minutes are sufficient for execution, a field of battle, with its successive phases, can be drawn with a degree of perfection that could be obtained by no other means. So from the beginning of photography, it was being seen as a means of depicting war scenes. The American poet Oliver Wendell Holmes, writing in 1863 stated: `It is well enough for some Baron Gros or Horace Vernet to please an imperial master with fanciful portraits.... (but) war and battles should have truth for their delineator', and photography would be more suitable for this. One of the great names is that of Mathew Brady who, with a large team of photographers, covered the American Civil War. One member of his team was Timothy O'Sullivan,whose picture "Harvest of Death", taken at Gettysburg on 4th July 1863 ranks amongst the most famous of early historical photographs. To some extent it is difficult to avoid seeing pictures showing the ravages of war; indeed to some extent we have become almost immune to it. To many people of the time, however, war would be something that was conducted in far-off lands, and therefore would conjure up pictures of heroism and romanticism. Writing in the Atlanta Monthly magazine, Oliver Wendell Holmes showed how photography injected a feeling of grim reality into the situation, as he surveyed pictures taken by Brady's team: "Let him who wishes to know what war is look at this series of illustrations. These wrecks of manhood thrown together in careless heaps or ranged in ghastly rows for burial were alive but yesterday... Many people would not look through this series. Many, having seen it and dreamed of its horrors, would lock it up..that it might not thrill or revolt those whose souls sickens at such sights. It was so nearly like visiting the battlefield...that all the emotions excited by the actual sight..came back to us. (It) gives us....some conception of what a repulsive, brutal, sickening, hideous thing it is, this dashing together of two frantic mobs to which we give the name of armies..." What effect might this have upon those who saw the photographs? Artists could romanticise the event; photographs told the truth (Well, did they?! Not necessarily!) One beneficial effect might have been to become more aware of the ordinary soldier, and his plight. In 1855 a telling cartoon in Punch, a British journal, depicted two soldiers in rags. The caption underneath the cartoon reads: "Well Jack! Here's good news from Home. We're to have a Medal." That's very kind. Maybe one of these days we'll have a coat to stick it on?" Whilst touching upon "true" photographs, there were many "war" photographs whose takers never went near any scene of conflict. These include Nadar in France, Cundall and Howlett, whose "Crimean Braves" photographs were finished before the troops set sail! There was also a certain amount of embellishment that seems to have been readily accepted in those days. See Gardner Relatively unknown is John Maccosh, an army surgeon who may have the distinction of being Britain's first war photographer. He began to take photographs in 1844, whilst stationed in the Himalayas, and took photographs during a Sikh War (1848) and the second Burma war (1852) In the American Civil War a balloon was used to find the enemy's positions, notably for reconnaissance during the siege of Richmond, Virginia: on 1st June 1862 the balloonists climbed to 1,300 feet, and with the aid of telegraphy were able to report the exact position and movement of the enemy. An unusual application of photography in war was the use of carrier pigeons during the siege of Paris, when minute photographed messages were 158 attached to their tails. (See Micro photography.) Even at the turn of the century the forces were ambivalent about war photography. IN an article in Amateur Photographer (Jan 4 1901) H. C. Shelley suggests "You have to find out your general before beginning operations." And referring to his attempts to photograph Sir Redvers Buller: "...the general went up to the captain's bridge to watch the oncoming boat. I crept after him, camera in hand, and in a flash the exposure was made. But he heard the click of the shutter and, turning round, and grasping the situation at a glance, he grimly threatened to have me placed in irons if I repeated the operation." WATKINS, Carleton E b 1829; d. 1916 A prolific and outstanding American photographer, Watkins was famous for his panoramic views. In the early 1860s he explored the Yosemite Valley to take photographs. At that time, of course, sensitising, exposing and processing had to be done on the spot, so he had taken with him twelve mules for his equipment, together with a converted wagon, which became his dark room. He used huge glass plates measuring 40 by 50 centimetres. WAXED PAPER Process One of the problems of the calotype process was that as one had to print through the paper negative, the imperfections of the paper would also show. Care was taken to ensure that the right kind of paper was used. However, the more transparent the paper, the greater the definition. It was quite a common practice to wax the calotype negative after it had been developed and fixed. However, Gustave Le Gray introduced, in 1851, a process whereby waxing was part of the process prior to exposure and development. Le Gray's process also enabled the paper to be kept a week or so before use. However, though it showed a definite improvement in definition, it was also slower than the calotype process; sometimes exposures of up to fifteen minutes in sunshine were sometimes required. It was for this reason that most of the subjects using this process were inanimate. WEDGWOOD, Thomas b. 14 May 1771; d. 11 July 1805 In 1802 Thomas Wedgwood (son of the famous potter Josiah Wedgwood) together with Sir Humphrey Davy presented a paper entitled "An account of a method of copying paintings upon glass and of making profiles by the agency of light upon nitrate of silver." He had worked closely with Davey, and their work was very nearly a breakthrough, for they had made what one can best describe as photograms. However, they were unable to fix the images, and the story is told that Wedgwood was reduced to examining his pictures furtively by the light of a candle. They also tried using a camera obscura, but the chemicals being used at the time were not sufficiently sensitive. In the report to the Royal Society, June 1802, Davy wrote: "The copy of a painting, or the profile, immediately after being taken, must be kept in an obscure place. It way indeed be examined in the shade, but, in this case, the exposure should be only for a few minutes; by the light of candles or lamps, as commonly employed, it is not sensibly affected." Wedgwood died three years later, aged 34. What neither he nor Davey could find was discovered in 1819 by Sir John Herschel. WET PLATE PROCESS The more popular name for the wet plate process is Collodion, invented by Scott Archer. It is called such because the entire process of coating the plate, exposing it, and processing had to be completed before the collodion dried. Women Pioneers of Photography Few women photographers are cited in the most popular books on the history of photography, for which there could be several reasons. One is that history has a habit of becoming repeated and in turn quoted, with the result that it becomes the established lore even when the story may have been incorrect. In fact, women were very active in this field and deserve far greater prominence than has been accorded to them. This brief article can only scratch at the surface; those wishing to pursue this further are well advised to read "A History of Women Photographers" by Naomi Rosenblum, published by the Abbeville Press (ISBN 1-55859-761-1). This book makes illuminating and compelling reading, and the author of this article has drawn heavily upon it. Those familiar with the ordeal of taking photographs in the earliest days would sympathise if women were to regard this new activity as not being their cup of tea. In the earliest days, development would be needed immediately after exposure; consequently the equipment needed for photographs outside a studio would be cumbersome. In addition, the chemicals could be smelly, and the whole process initially was a bit of a hit-and-miss affair. However, this clearly did not deter women from being actively involved in picturemaking. There is also evidence that women did not receive the acknowledgement due to them inasmuch as many accepted a more supportive role for their husbands. Of those who participated, a number would be relatives of a male photographer. Fox Talbot had a number of female relatives who were active in this field, and indeed his own wife, Constance, both took pictures and developed and printed them. Emma Llwelyn printed for her 159 husband, John Llwelyn. Robert Tytler photographed the ruins following the Indian Mutiny of 1858; his wife Harriet accompanied him, and though the work received much acclaim, the records only mention the husband's name. Elizabeth, wife of Disderi, famous for his carte-de-visites, was in partnership with her husband, and continued to operate in Paris after his death, until her own death in 1878. It says much of the times that her death certificate cites "without profession, 61 years old." There follows the names of a few women who practised photography in the earliest years: Laure Albin-Guillot (b. 1880; d. 1962) together with her husband, spent many years photographing specimens, plant cells and animal organisms. She also produced nudes and soft-focus portraits, and wrote articles on photomicrography. Berenice Abbott studied with Man Ray in the early 1920s, and was almost solely responsible for preserving the work by Eugene Atget. Anna Atkins(b.1799; d. 1871) became the first person to print and publish a book, photographically illustrated. On her tombtone in Halstead, Essex, her husband is referred to as a JP, but she is simply referred to as "Daughter of..." - again a sign of those times. Alice Austen (b. 1866; d.1952) was an American photographer. She received a camera at the age of ten, and never looked back! In addition to many family and local interest photography, she became involved in documentary work. Having lost her money and home in the 1920s stock crash, she was for a while in the equivalent of a poor house, though her work ultimately became recognised and she was able to live comfortably for the last years of her life. Emma Barton (b. 1872; d. 1938) lived and worked in Birmingham and in the Isle of Wight. One of her pictures, "The awakening", gained her a medal from the Royal Photographic Society in 1903. Alice Boughton (b. 1866; d. 1943) was an American photographer whose work included pictures of children, portraits and theatre. For a while she worked in the studio of Gertrude Kasebier. She became a member of the Photo Secessionist movement. Some of her pictures are in Camera Work. Anne W. Brigman (b. 1869, d. 1950) was an American who produced a number of nude and draped figures in landscape. She was a close friend of Edward Steichen, and exhibited in the Photo-Secession exhibitions. She too had some pictures published in Camera Work. Christina Broom (b. 1863, d. 1939) has sometimes been referred to as the first British woman press photographer. The number of events she covered included Derby Day, at Epsom, Surrey, investitures of monarchs, women suffrage demonstrations, the Oxford and Cambridge Boat race, and the Royal Mews at Buckingham Palace. Bessie Buehrmann was an associate of the Photo-Secession group. Her consisted mainly of portraiture. Julia Margaret Cameron b.1815; d. 1879, is without question the most well-known woman pioneer in photography. Mary Cassatt (b.1844, d. 1926) was an American-born impressionist, famous for her paintings of mothers and children. One of her pictures was published in Camera Work. Nancy Ford Cones (b. 1869, d. 1962) worked in photography in the latter stages of the period covered by this work. She operated in Ohio. Kodak used some of her work for publicity purposes. In a Kodak competition of 1905, she received second prize for a photograph entitled "Threading the needle", Edward Steichen winning the competition, and Alfred Stieglitz coming third. Clementina Hawarden (born 1822, died 1865) operated in South Kensington, London, and produced hundreds of images of her family and nearby surroundings. She was awarded a medal by the (then) Photographic Society, though she died aged forty-two, before receiving the award. Many of her prints are owned by the Victoria and Albert Museum, London. Frances Benjamin Johnston (born 1864, died 1952) was an American photographer who opened a studio in Washington in 1890. She was much in demand photographing celebrities of her day, and had several assignments photographing in the White House. In 1897 she published an article entitled "What a woman can do with her camera." Gertrude Kasebier (b. 1852; d.1934) was the first woman to be elected to the prestigious Linked Ring. Theresa Llwelyn, a distant relative of Fox Talbot used "photogenic drawing" (photograms) of seaweed specimens. Agnes Warburg (b.1872; d.1953) was inspired by her elder brother to take up photography. She exhibited at the Photographic Salon of the Linked Ring and at the Royal Photographic Society, where she was highly active. She was a founder-member of the Society's Pictorial and Colour Groups. She specialised in landscapes and portraits, and also experimented with the autochrome colour process. Catharine Barnes Ward (b.1851; d. 1913) was an American photographer who later lived in England. She became associate Editor of the American Amateur Photographer in 1890, was a popular lecturer, and a strong supporter of women photographers. She joined the Photographic Society in 1893. In 1893 she married Henry Ward, the founder and editor of the magazine "Practical Photographer." Her works included a well-illustrated "Shakespeare's Town and Times" , books on Dickens and the land of Lorna Doone. Jane Wigley, an English photographer, purchased the franchise to operate from Beard, and worked in Newcastle and London. It is stated that she was one of the first to use a prism in the camera so as to reverse the daguerreotype image. 160 These are just a few of the many women early pioneers of photography, doubtless many more being unheralded and, at present, unknown. Again, those wishing to pursue this area further should read Dr. Rosenblum's remarkable book, which covers the entire period of photography from the earliest days up to the present. WOODBURYTYPE process This is a form of photographic printing, mentioned here because it appears almost identical as a photograph. The process was patented by Walter Woodbury in 1866, and is similar to the carbon process. The great feature of the Woodbury process is that a photograph in gelatine is caused by enormous pressure to indent a sheet of lead. The quality of the pictures was remarkable, with no grain, and the process was widely used until the turn of the century. 161 162 163
