Bleach bypass

Bleach bypass can be done to any photochemical step in the process, be it original camera negative, interpositive, internegative or release print.

For motion pictures, it is usually applied at the internegative stage, as insurance companies usually are reluctant to have the camera negative bleach bypassed, or the interpositive (a "protection"/"preservation" element), in the event that the look is agreed to be too extreme, and the cost of the process for each individual release print is most often cost-prohibitive.

Kazuo Miyagawa, as Daiei Film's cameraman, invented bleach bypass for Ichikawa's film,[2][3][4] inspired by the color rendition in the original release of Moby-Dick (1956), printed using dye-transfer Technicolor, and was achieved through the use of an additional black-and-white overlay.

Despite this early foray into the technique, it remained overlooked for the most part until its use by Roger Deakins for the movie Nineteen Eighty-Four.

Practitioners include cinematographers Rodrigo Prieto, Remi Adefarasin, Darius Khondji, Dariusz Wolski, Walter Carvalho, Oliver Stapleton, Newton Thomas Sigel, Park Gok-ji, Shane Hurlbut, Steven Soderbergh (as "Peter Andrews"), Tom Stern, Vittorio Storaro, and Janusz Kamiński (notably on Steven Spielberg's Saving Private Ryan[5] and Minority Report).
