I'm about to process some new Delta 400 (120 format) with PMK and am looking for a start point for developing in a Patterson small tank. Doea anyone have a recommended time, temp, and agitation plan for this combination? I'd also be interested in what your effective EI was for this combination.(posted 8523 days ago)I'm currently using PMK with the standard 10/20/1000 dilution at 70F with 2 firm inversions every 15 seconds, water stop, TF-4 fix, 2 minute developer after-bath, and 20 minute wash.
