Bleach bypass, also known as skip bleach or silver retention, is a chemical effect which entails either the partial or complete skipping of the bleaching function during the processing of a color film. By doing this, the silver is retained in the emulsion along with the color dyes. The result is a black-and-white image over a color image. The images usually have reduced saturation and exposure latitude, along with increased contrast and graininess.[1] It usually is used to maximum effect in conjunction with a one-stop underexposure.
