In this forum or another, Ed Buffaloe (Unblinking Eye) posted a fascinating report that he had tried a number of Amidol formulas, but when he finally tried the one that Paula and I use he got the best results ever. The formula we use came about after I spent years of experimentation. Some people like to experiment. I do not. I prefer to spend my time making photographs. The only reason I experimented before was that I was not getting the results I knew were possible. Since I found what worked, there was no reason to experiment further. In general my advice is to go with whatever works until you are not satisfied with the results. Only then, experiment with other formulas and processes.
