Bleach bypass, also known as skip bleach or silver retention, is an optical 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 would have reduced saturation and exposure latitude, along with increased contrast and graininess. It usually is used to maximal effect in conjunction with a one-stop underexposure.

Famous quotes containing the word bleach:
“A bone,
polished in wet and sun,
worried of wild beaks,
and of the whelps’ teeth
worried of flesh,
left to bleach under the sun.”
—Hilda Doolittle (1886–1961)
