Bleach-Bypass color negative film with these 2 simple chemistry mixtures!
The "Bleach-bypass" color process, also known as skip bleach or silver retention, is a process of skipping the step of bleaching during processing of color films. By doing this, silver is retained in the emulsion along with color dyes. The result is a black and white image over a color image. The images usually have reduced saturation along with increased contrast and graininess. And if you ever want to remove the effect you can simply process it in the Bf41 bath included in our Cs41 2-Bath Kits.
Motion Picture "Bleach-bypass" was first used in cinematography by Japanese filmmaker Hiroshi Inagaki in film Rickshaw Man (1957). Kazuo Miyagawa, as Daiei Film's cameraman, invented bleach-bypass for Inagaki's film, 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. Actually, this is a throwback to pre-1944 Technicolor, which incorporated a silver-containing "blank receiver". Despite this early foray into the technique, it remained overlooked for the most part until its use by Roger Deakins for 1984 (1984). The effect has subsequently become a regular development tool in labwork, and has remained in widespread use. 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 and Minority Report.

If you already process your own black and white film, there is no reason not to process C-41 color negative film at home as well! It is specially formulated without compromise for modern color films, not requiring a stabilizer bath. Modern emulsions were designed so that one-hour photo labs wouldn't need haz-mat training for formaldehyde, and have built-in dye stabilizers and hardeners that are released through the simplified 2-bath process. You can have beautifully developed, bleached and fixed color negatives, ready to scan or print. All you need is water, a thermometer and any simple tank and reel system!
