I've done 400 - ? or so - rolls of C-41 but always using the Bleach-Fix form the Kits; Tetenal, Photocolor, Agfa, etc. This is the first I've heard of Pottasium Ferricyanide applied to color processing.
Are you mixing your own chemicals? What formulae do you use? What about the fixer? The chemistry in the kits has always been identified as "Ferric-Ammonium EDTA" (or something like that .. I don't have the data sheets handy) ... is something else appropriate?
I am most interested.
