As I recall, Picker said that Zone VI developer was like Dektol but that it didn't "dump" the low values in the way that Dektol did. I have to believe that there was a proprietary formula involved. I posted several months ago asking for information on the formulation but came up with nadda. I like the Zone VI developer for conventional enlarging, as well. If I were to try to come up with a formulation, I believe that I would check the Darkroom Cookbook. Perhaps Ed Buffaloe would have some knowledge of the formulation.

Lacking that perhaps we could invite Fred to a seance. Heck he wouldn't mind letting us in on his secret now...
