Hi Ken ... I've wondered about that recently. I used to work very hard to maintain constant temperature across the entire process, but a couple of years ago, in an Ilford or Kodak instruction sheet, or in one of kodak's photo guides, it was clearly stated that as long as the stop, fix, and rinse are within a few degrees of the development temperature, results will be satisfactory.
The problem as I understood it was reticulation, not grain clumping per se. Try as I might, I can't get reticulation at all these days. However, I agree that one should try to maintain an even temperature throughout the process, and would even go so far to suggest maintaining a 1-degree +/- tolerance. I just wonder how necessary it is these days. Ken Archer wrote: > > I don't want to over react, but nothing could be further from the > truth.
