"I found it to give somewhat more graininess and lower acutance than D-76 1:1 or Xtol 1:1 with HP5+."(posted 8939 days ago)I find it very hard to believe that someone that wrote this statement has actually used PMK. I've found the exact opposite over the years I've been using pyro.
I don't look at grain through a microscope I only care how it prints and I never see grain in 6x7 negs printed to 11 x 14. As for supposedly having lower acutence, you've got to be kidding
