On Riuji's council, I purchased Grant Haist's two volume set of wonderful reference texts (thanks Riuji) and he has a great treatment of reversal technology in volume II. He, however, doesn't like permanganate and says not to use fericyanide. He recommends acid dichromate as bleach. I also get the impression that he's not too keen on thiosulfate in the first developer either. He essentially says that controlled light reexposure is best but details how to use chemical fogging also. Here, of course, he is coming from a MP perspective using machine processing. I need reagents and instructions for small tank use (in his defense, he lists these too but as an afterthought). Could the members here give me some guidance on links to web sites devoted to reversal B&W processing. I am marginally computer literate and get way too many hits with Google to troll through.
