How I shoot checklist?
1. Examine Event Surroundings.
2. Determine ISO settings. How much light is in here?
3. Will I use the flash?
4. White Balance if lighting will stay the same and if you have time.
5. Switch to Shutter Priority (TV) Mode on Canon Camera.
6. Set Focus Point on subject.
7. Shoot some sample shots before event starts
8. Adjust settings for proper exposure.
The right ISO for the right situation.
•
What is ISO?
ISO is essentially the “film speed” or “film sensitivity”.
•
The lower the ISO number the more light it needs.
ISO 100 - 250 Typical Usage: Bright Day, Studio Lighting, Flash
•
The higher the ISO number the less light it needs.
ISO 800 - 1600+ Typical Usage: Classroom Lighting, Auditoriums, Offices
Low ISO (100 - 400 )
equals Less Grain/Noise
Aperture Priority - AV mode
Shutter: 1/2
Aperture: f 5.0
ISO: 100
High ISO (400 -1600+ )
equals More Grain/Noise
Aperture Priority - AV mode
Shutter: 1/50
Aperture: f 5.0
ISO: 3200

Aperture - (F-Stop)
The aperture controls the size of the lens opening that allows light into
your camera.
•
To Blur Background & keep foreground in focus,
Use wide aperture (small number) f-stop (ex. f/1.4)
•
Shallow depth of field
•
Remember! Wide aperture (smaller number) f/1.4 lets more light in and will allow you
to blur background.
•
Darnits!
Shooting with a wide aperture (small number) f/1.4 may not give you the
most controlled focused shots.
Aperture - (F-Stop)
The aperture controls the size of the lens opening that allows light into
your camera.
•
To keep everything in focus, Use smaller aperture (bigger number) f-stop (ex. f/9+)
•
Wide depth of field
•
Remember! Smaller aperture (bigger number) f/22 lets less light in, but it will allow
everything to be in focus
•
Darnits!
Shooting with a smaller aperture requires more light.
Fix by using higher ISO.
