A newbie question for y'all: I'm gearing up to shoot and process some 4x5 FP4+, but
a quick recce of the community darkroom I've joined revealed that the water/ambient temperature I'll be working with is 75-77 degrees.
I understand that I'll need to cut development times by up to a third for "normal," intermittently agitated runs, but was curious if I needed a similar fudge factor if I wanted to try semi-stand (e.g. "EMA") with 1:1:150-200 Pyrocat, given that the chemistry "self-regulates" (if I understand correctly) as the reagents chug on toward exhaustion.
Any thoughts appreciated--it might be that I might need to take steps to get to 68-70 before getting too far down this road, but since the workspace is a "commons," I'm hesitating before rolling in with a bag of ice.:)
