(November 2008) Chromogenic refers to color photographic processes in which a traditional silver image is first formed, and then later replaced with a colored dye image.

Description

Chromogenic film or paper contains one or many layers of silver halide emulsion, along with dye couplers which are capable of forming visible dyes in combination with processing chemistry. In processing, the silver image of each layer is first developed. In concert with the dye couplers in each layer, the process subsequently forms dyes only in those areas where silver is present. In full-color chromogenic materials, multiple layers of emulsion are sensitized to different wavelengths of light. Three layers are usually present, generally sensitive to red, green, and blue colored light. Cyan-colored dye is formed on the red-sensitive layer, magenta-colored dye is formed on the green-sensitive layer, and yellow-colored dye is formed on the blue-sensitive layer, following generally the CMY color model. Some chromogenic black-and-white negative films also exist, mainly to exploit the wide availability of C-41 processing. These films have softer gr... mehr
