I had forgotten that I had mixed a small test batch of this developer a couple of months back and never got to it. Yesterday, I had a roll of 120 PanF+ and HP5+ with non-important images that had my lazy tendencies steer me to doing in one tank at the 4 minutes A and 4 minutes B recommendations in my notes. The films were exposed at 1/2 box speed, studio flash and a few on-camera flash. The HP5+ was very low contrast and thin but they look printable if they were important enough to deal with. The PanF+ were very dense, radically different in all respects, having much, much more contrast.
I guess I didn't know what to expect but certainly not such a radical difference. The grain pattern is very pleasing (very fine but "edgy") and could merit a bit of tuning. Here's the formula paste from my spreadsheet:
Bath A Concentrate
Pyrocatechin 10 g
Sodium Sulfite 2 g
Potassium Bromide 0.5 g 7.7 grains Water to: 100 ml
Bath B Concentrate
Potassium Hydroxide 10 g
Potassium Bromide 0.5 g 7.7 grains Water to: 100 ml
Mix both at 1:14. 4 minutes each bath.
Agitation each 30 seconds in A and once each minute in B. No rinse between baths.
Part of my curiosity was that I have a large stash of the Pot Hydroxide and Catechol and I thought it would be handy if it worked for sharing tanks/film types universally.
