    Reverse processing

    I have a book somewhere that gives the chemistry for reverse processing (turning a negative into a positive) .... now, which book could that be? Anyone tried this at home recently? I think it involved dichromate, which I have.

    Reverse processing. I thought you meant fixer first, then stop, and finally developer. I accidentally did that once. I don't recommend it...

    ...unless you want really slow film for really long exposures. (post-fixation physical development)

    Off topic, but the Dr5 site has examples of various reverse processed films, using their process.

    Yes dichromate is used to bleach the latent image, re expose to light and redevelop. You can find a couple of very good articles in unblinkingeye.com.
