True-to-life colour saturation Precise colour tone The aim of film technology is to reproduce colours separation realistically, and without distortion. Excessive colour Precise, true-to-life colour saturation is just as great a distortion of reality as colour rendition is only possible if saturation which is too low. the correct colour tone is To prevent this distortion, Agfa uses various technologi- reproduced exactly.

When we talk about colours being vivid, intense, deep, or delicate, we mean our overall impression. Film technology has to go into more detail, building colours out of different components. The colour brilliance of a film is the collective result of many individual technical details. Two properties are of decisive importance in this process: colour saturation and colour tone separation. active inter layers with white couplers. Agfa Professional films prove that precise colour tone separation spells greater information density, enhanced trueness to life, and greater picture depth. 90 RSX II 100 b* 70 50 30 Colour separation of the primary colour area 10 -50 -30 -10 -10 10 30 50 a* -30 -50 The greater the area of the Cielab colour space, the greater the colour saturation.

The afraid primarily of technological answer: to achieve high information density Gradation is a factor that influences not only the contrast, but also the colours. The effects are noticed especially in the way greys, blacks, and whites, and areas of low and high colour density are reproduced. There are two key aspects here: grey balance and tonal gradation. “crossover”: for example from red highlights to green with Agfa Professional films in these areas as well, shadows.

It a host of quality properties which are to be found across comprises the necessary speeds in three product lines (colour negative films, colour reversal films, and black and white films). the range or in individual product segments. And specialist films, of course, whose properties are either geared to specific technical requirements or can be used for creative effects. There are a total of 13 film types available, in different formats, with all emulsions being available in 135 (35 mm) and 120 (roll film) formats. In addition, a 220 roll film format is available, as are various sheet-film formats and bulk lengths. In response to All Agfa Professional films feature: practical working requirements, the range also includes multiple packs and state-of-the-art film technology large rolls. extremely tight production tolerances ideal combination of the four quality factors: film speed, colour reproduction, sharpness, and grain balanced tonal gradation Agfa Professional “specialist” films: robust reciprocity characteristics For special requirements high storage stability In most Agfa Professional films, the four film-quality exceptional processing stability factors are well balanced, in line with their intended use. in portrait photography. The reduced colour satura- tion of the film promotes an attractive, natural effect, and prevents unwelcome skin colouring.
