For the small amount of film I now process, I've switched from C-41 to the C-41RA process. The RA process uses faster bleach and fixer solutions, for a total process time of about 8 minutes. I am using the solutions one-shot in a Jobo. The "RA" bleach is extremely expensive (though the Trebla version is slightly cheaper than the Kodak). This is probably because its replenishment rate is 1/10 that of the standard Flexicolor Bleach III (5ml per roll rather than 52ml). In fact, the replenishment rate is so low it approximates the amount of solution lost by carry-over into the fixer in a tank system, though it might not in a large dip-and-dunk. Kodak's process documentation does not give a one-shot capacity for the RA bleach or fixer -- it gives only the general advice that the capacity of bleach and fixer solutions used to exhaustion in is twice that of the developer. I am sure the capacity of the RA bleach used this way is not 10 times that of the standard bleach, but what is it? I know with small solution volumes capacity can have as much to do with build-up of byproducts and carry-over from the previous process step as with exhaustion, but I would hope I could, for example, reuse a tank of bleach at least twice, or use minimum volumes to cover the film with my (carefully-leveled) Jobo processor and tanks. By the replenishment rate (5ml per roll) both practices look like they should be just fine, but by Kodak's "twice the developer" instructions they are not. Opinions? I could call 800-242-2424, but I wonder if there is still anyone there who knows enough to help me when the written documentation can not.
