264 Bleach Bypass<br />

•<br />

BLEACH BYPASS<br />

Description<br />

Bleach Bypass is a film laboratory technique where, by skipping the bleach<br />

stage in the color processing sequence, silver is retained in the image along<br />

with the color dyes. The result is effectively a black and white image<br />

superimposed on a color image. Bleach Bypass images have increased<br />

contrast, reduced saturation, often giving a pastel effect.<br />
