I've been researching for hours, and I'm stuck. I'm doing an assignment on the chemistry of photography; and I have all the information. All I need is chemical equations for the following processes:
1. (in colour photography) how the AgX crystals are reduced by the developer, which is simultaneously oxidised
2. (in colour photography) how the oxidised developer reacts with the dye couplers to form coloured dye
3. (in colour photography) equations to do with the film-bleaching step in development/fixing
4. (in cyanotypes) what happens when the film/paper is exposed to the UV light (ferric salt is reduced etc.)
5. (in cyanotypes) how ferrous ferrocyanide is reduced to ferric ferrocyanide
This is a last resort, and any equations or links to places I could find the equations would be greatly appreciated!!
Thanks!
