Example text

This type of film is known as chromogenic film for its ability to generate colors from the latent silver halide image. This kind of spectral sensitivity filtration, together with dye coupling and eventual bleaching, is the basis for all color negative films, slide films, and color prints. Not all films generate color through dye coupling, however. Kodachrome’s color is introduced during film development rather than being present in the emulsion itself. , long lasting) than regular film. No matter what kind of film is used, photography is still about the capture and control of light as it falls on a scene or subject.

This has not always been the case, however. In early color film, dye migration was a problem. The dye moved and mixed with the other colors and ruined the color balance. Modern color films are composed of a top blue layer, a green middle layer, and a bottom layer that is sensitive to red light. The layers change color once they are developed. The top blue layer becomes yellow, the green layer becomes magenta, and the red layer becomes cyan. The film behaves this way because the fixed dyes in the film are complementary to each original color.

This creates what is called halation. Halation creates secondary ghost images in the film, which to photographers is bad because they are a by-product of unintentional light and film interaction. F IGURE Light interaction. 1 CHAPTER 3 FUNDAMENTALS OF PHOTOGRAPHY AND CINEMATOGRAPHY F IGURE Light passing through film. 2 Most modern films have an antihalation backing to prevent this from happening. Antihalation backing is normally dark brown when dry and after development is sometimes seen dissolved as a pinkish-red coloration.
