Response to PMK, Jobo and HP5+ for 35mm

Formulary also sells PMK with EDTA. The EDTA seems to help with streaking. I use it on a Uniroller 352 and have had good results. Your times are going to vary widley depending on paper/developer/enlarger/enlarger filtration/contrast filter etc. My best advice is to find .15-.20 +fb+f on Zone 1 and adjust Zone VIII to match your enlarger for just off paper base white at the same time you reach dmax. Gordon's book serves only as a reference, YMMV.
