B&W film will bleach with Farmer's Reducer or reversal process bleach. The image is a silver image, so what you're doing is reacting with the silver to form a soluble salt that you can clear out.
However, the B&W emulsion is also designed for low temperature processing so another route is to put it in very hot water and just dissolve all the gelatin right off. I once sent an edited negative containing color and B&W sections to Commonwealth Film for processing. Even though the can was untaped some bozo ran the whole thing through the color processing machine and the B&W sections were all perfectly clear afterward because the emulsion was all completely removed. Color film is going to be more problematic... if it is long perf it's probably best to just use it for soundtrack fill... --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
