The dominant photographic color process of the 20th century is made up of three gelatin layers containing cyan, magenta, and yellow organic dyes. Together, these dyes produce a full-color image. From 1935 to the present day, the chromogenic process has been used to create a range of print, transparency, and film materials. Common branded products such as Kodacolor prints, introduced by Kodak in 1942, use the chromogenic process, as do materials produced by other companies such as Fuji and Agfa. Used by both professionals and amateurs, chromogenic prints, also known as “C prints,” can be unstable and prone to color shift or fading.
