BleachBypass is a Photoshop-compatible plug-in designed to digitally simulate the traditional film "bleach bypass" technique.
The bleach bypass, or "bleach skip" technique involves the partial or complete skipping of the bleaching stage during the processing of a colour film. This prevents the silver from being removed from the negative, and the result is a contrasty image with muted colours. The technique is often used extensively in motion pictures, such as "Saving Private Ryan" and "Three Kings".
It also gives a very pleasing, "film-like" quality to images, much like older, fast print film was used.
