Although Homolka noted that these developers could create beautiful photographic effects, he didn’t suggest using this developer in a color photographic process. In spite of this, Fischer never created a successful color print due to his inability to prevent the dye couplers from moving how to print color pdf the emulsion layers. Kodak, describing the structure of a chromogenic print.
Agfa’s for their dye couplers, which were suspended within droplets of water in the gelatin layers. In 1955, Kodak introduced a chromogenic paper named “Type C”, which was the first color negative paper Kodak sold to other labs and individual photographers. Type-R Print” becoming its reversal film counterpart. Their works and those of many others caused chromogenic prints to become the preferred medium for contemporary photography by the 1990s. Chromogenic processes are characterized by a reaction between two chemicals to create the color dyes that make up a print.
In its reaction to the print, the color developer is oxidized in the areas of exposed silver, and subsequently reacts with another chemical, the dye coupler, which is present throughout the emulsion. Different dye couplers are used in each of the three layers, so the reaction forms a different colored dye in each layer. Responding to both exposure and development, a blue-light-sensitive layer forms yellow dye, a green-light-sensitive layer forms magenta dye, and a red-light-sensitive layer forms cyan dye. The remaining silver and silver compounds are then bleached out, leaving a color image composed of dyes in three layers. The print’s name is derived from the chromogenic reaction between the dye coupler and the oxidized color developer. Type R paper, although Fujifilm still has some stocks remaining.
