Recent discussions in here regarding reticulation touched on the pH shock effects. I've been noticing a temporary reticulation that appears as a "frosty" sort of finish when I first hang my washed films up. I notice it most on medium format Tri-X but also on Ilford films, too. When fully dried, it seems to not be apparent and the film seems normal (perhaps a very vague retention of pattern under a 45X viewer). In a recent "Duh" moment, I realized that I started seeing this about the time I was switching to an alkaline fixer (TF-4). Is there some sort of pH related issue at work here? I'm skipping the acetic acid and using 3 flushes with tempered water following my developer (FG7 w/o ss, Exactol Lux and W2D2+). I'm quite certain my tempering methods rule out temperature related issues.
