dye-destruction process
Quick Summary
The dye-destruction process in photography is a method where color images are created by bleaching dyes in proportion to a formed silver image. Unlike chromogenic processes, dye-destruction materials start with emulsion layers containing the final dyes.1
The basic steps for a dye-destruction process include:
1. Developing a silver image.
2. Stopping development and removing unexposed silver halide.
3. Bleaching the dye in areas with a silver image.
4. Converting the silver image into silver halide.
5. Removing any remaining silver halide.
Washing is performed between each stage. Dye-bleach materials use dyes that are more stable to light than those produced by color-coupling development. This process is distinguished from the bleach-out process.12
