Really you don't recommend rotary process for PMK.. I have only done PMK in my company for 18 years, I may owe a lot of people a lot of money for that screw up.
Another example with Foma 200:
I concur.. do not reuse the developer for a second run.
Didn't quite get that one, Bob... do you, or do you not use it rotary? I found that even at low RPM's, PMK had too much aerial oxidation for
rotary and led to excess fog, or worse, potentially excess edge dev which thicker emulsions. You could print thru it generally, but it certainly
isn't desirable. That's why Hutchings recommended argon gas for rotary, and why tweaks like Rollo-pyro came along. My drum processors are
capable of running a lot slower and more gently than the Jobo, and I'd never go back to using them for PMK.
I have run thousands upon thousands of runs of PMK on Rotary Jobo, actually in the middle of a series of runs right now and over this weekend.
Have been doing this for over 18years.
Yes but all Sandys current neg's are done as always, he also has been playing with an IR cheater camera.
I like PMK , but I also like ID11 and other developers, basically it boils down to what lighting ratio you are trying to capture , with an exposure developer plan .
Well, staining pyro formulas have made a gigantic difference for me in terms of printing ease and quality, in all formats. Saying you quit because of something Brett Weston said way back when might not have any relevance with today's films and papers. But at that point in time he mainly shot medium format using Agfapan, and deliberately underexposed and overdeveloped to give him those famous blacked out graphic shadows. So if you want to eat your cake and have it too, with reference to detail in both the deep shadows and upper highlights, that approach won't work so well. There are all kinds of pyro formulas, some based on pyrogallol and some on pyrocat. Once LFF is back up, one can look up the "pyro war" threads of past years, which got pretty brutal between different potential formula tweaks. I eventually threw a few punches myself. I don't know how Bob does it in a Jobo unless he uses an awful lot of solution volume to keep the air out in the first place. I personally keep about a dozen different film developers in the lab, mostly for specialized purposes, but like I said earlier, still prefer
basic PMK for general usage.
The Book Of Pyro may be 21 years old, but there are still some gems in it.
PMK didn't work for me because I mainly use BTZS tubes. I switched to Rollo pyro, which essentially is PMK, but for rotary. In the end I switched to Pyrocat-HD, because I prefered the look, and of it's ability to give extremely high aqutance in stand/semi-stand devleopment.
Still love Xtol, and D-19. To each his own.
