REDSCALE FILM PHOTOGRAPHY
Redscale film is just normal 35mm colour film that is reversed - ie take the film out of the canister (in a dark bag), cut it at the end - then flip the film over. Sticky tape the end back on and respool the film into the canister before loading into the camera as normal.
I didn’t do this - I just bought the film pre-prepared from Nik & Trick, a specialist camera retailer. And because it is just colour film, you can process it locally using C41 processing
