Howard, the dilution I gave was 1:1:6, or add one part stock A to one part stock B and then add 6 parts water. Or if you like, simply add 1/2 of a part of A and B together, and of this total amount, add 3 equal parts distilled water. Pat Gainer's original recipe specifies a 1+3 dilution for film. My 1:1:6 is faithful to that when using Ted's stock A and stock B solution approach. I chatted with Ted about this last evening and he graciously conceded that his 1:1:14 dilution was in error, but regardless of that error, seems to work well using hand tanks and low agitation.(posted 8221 days ago)As for the shelf-life longevity or the wisdom of the chemistry in this developer recipe, I'll leave that to smarter people than myself. All I can say is that I agree with Ted's superlatives when describing the results of this developer recipe.
