Why does nobody mention stand developing turns Tri-X into a totally different film?
I let a roll of Tri-X sit in Rodinal at 1:100 for a full hour with no agitation, just two flips at the 30 minute mark, and the highlights came out way softer than my usual 1+50 routine. The shadows held more detail too, which I did not expect from a roll I shot at box speed around my neighborhood in Portland. Only downside is I have no idea how to time a second roll now that I like this look. Does anyone else stand develop and just guess at the timing, or am I the only one winging it?
The highlight thing is real but it's not the stand part doing it, it's the 1:100 dilution. Rodinal is a compensating developer at high dilution no matter how you agitate it, so you'd get that softer highlight rolloff even with normal agitation. The shadows opening up is the stand part though, since the developer exhausts in the highlights and keeps working down in the shadows while it sits there. As for timing, most folks just pick a time and stay with it, like 60 minutes at 1:100 is kind of the standard starting point. You can push it to 90 if you want more punch but you're not really guessing so much as tweaking one variable at a time.
