Dye-bleach processes are photographic or printing techniques in which selected areas of pre-formed coloured dyes are chemically removed or bleached, leaving the remaining dyes to form the final image.
This method allows precise control over colour and image composition, producing vibrant, detailed results. Dye-bleach processes are often used in colour printmaking, specialised photographic printing, and certain professional colour film processes, enabling artists and technicians to manipulate images for creative or corrective purposes.
