After exposure, the black-and-white development, and then bleached, then the emulsion layer of silver in accordance with the density of the image is reduced bleaching, unexposed part of the dye remains, according to subtractive color principle can be used for silver bleach Color film dyes should have the following conditions: 1. Spectrum absorption close to subtractive color theory of the three primary colors.
