I am about to return to printing after something of an absence. I have historically used Ansco 130 with benzo substituted for Kbr, and now want to try Amidol now that I'm a better printer, and have been perusing formulae for a starting point. I prefer cool-toned images, and have been curious about trying benzotriazole as the only restrainer in an amidol formula, but seem to find conflicting information about it's compatibility. I have found Fein's Amidol formula of course, which has no bromide at all, just benzo - BUT I've also read (Darkroom Cookbook) that Benzo does not function at the mild ph of an Amidol developer. Is Fein's poorly formulated? Or does the extra Sulfite bring up the ph enough to activate the benzo? ... but then again what about all that citric acid added? Can someone straighten out this conflicting information for me? - I'd love to omit the Potassium Bromide for the coldest tones, but would like to find an effective starting point for a formula before squandering precious Amidol! Thanks!!
