BLEACH #1: One sort of bleach converts (rehaloginates) the silver part of the image back into a compund similar to the original silver halide in the
unexposed image. Then the fixer can remove that reconstituted silver halide.
BLEACH #2: In developing colour films, a molocule of colour dye is also formed for each molecule of exposed silver halide turned black by the developer.
Once the dye molocules have been determined by the silver image, you no longer want that silver image.
This other sort of bleach then removes that silver part of the image leaving only dye, as was mentioned.
I'm pretty sure this is correct.
Anybody want to confirm or correct this? Please.
(I know some of the spelling is probably wrong.)
