No. Chlorine bleach will ruin the film. The recipe for the bleach is on the left side of the page, about halfway down under "Mixing the Chemicals"beamascope wrote:So when they say BLEACH do they mean simple bleach? Like the stuff for use in laundry?
Looks really easy with short rolls of one or two meters, but I have my doubts about 10 or 33 meters of cine film!'Apron' Spiral Loading Tanks
The first tank had a circular moulded plastic body with a light-tight lid. Inside was a plastic bobbin (reel) with plain end faces, between which could be wound a length of celluloid (called an 'apron'), the same width as the film. This apron had little projections on its edges so that when the photographic film was wound within it, the film was touched only by the projections.
As they touched only the perforated part of the film and not the picture itself, the developer had access to all the picture area. Once the loaded reel had been placed inside the light-tight tank in the darkroom, the whole thing could be brought out into normal lighting. The necessary chemicals were then poured in and out without exposing the film to light. This soon became the standard way to develop 35mm films."
