Response to Why do I get reticulation only with Tri-X ????????

from Keith Nichols (knichols1@mindspring.com)
Here in Dallas, I've been doing what you do every summer for 35 years (developing at 70 F and washing at 86 F) and never have seen a sign of reticulation in Tri-X or other film. I do not go directly from 70 F to 86 F, however. After development, I use a water stop at about 75 F, followed by a fix at about that temperature, followed by a dehypo solution at 80 F or so, and then put the film in water at about 80 F and flow in the 86 F tap water rather slowly to displace the 80 F water. I wash about three minutes in the 86 F water. I then dunk the film in some detergent solution at 86 F and hang it in still air without squeegeeing, since the warm emulsion tears rather easily. The detergent is intended to reduce droplets and mineral deposits, but I doubt that it does that much good. I don't get that much mineral deposit, anyway. The cooler solutions are made by tempering tap water with refrigerated water.
