Checking FP4+ and PMK dev times...

[Drew Wiley]

I've always used ASA 50 for FP4 in PMK to get better shadow gradation. My "N" is 10 min @ 20C, 1 liter solution in an 11x14 dimple-bottomed stainless tray in a larger water jacket, typically four 8X10 sheets at a time, gently interleafed every 30 sec, emulsion up. 2 min presoak plain water first.

I also use 50 iso for FP4 , my time for -n is 11 min with Jobo and two developers so I probably get denser negs than Drew but this time and rating works very well for me.

Thanks again, guys!
Feel a bit silly not checking this stuff out before I shot the film... I hope I get some useable results...

The big question in your quest for certainties is "do you know what actual speeds your shutter is delivering?"

[Drew Wiley]

That's easy enough. Get a shutter tester.
