I've been using PMK for a few years now with roll film. I'm now trying to use it with LF, and am having some problems. I have searched, and found a few posts relating to this exact topic. I used the suggestions found there as well as in Gordon Hutchings' book. Emulsion down, 1 cycle per 15 seconds. I'm using HP5 @ 13 min for normal, @ 70F.
I processed one fogged negative, and one real negative, the results are attached. The real negative looks fine, the fogged one... well, see for yourself. The real negative is complicated, so the flaws probably aren't visible, but I wouldn't want to process a negative with empty skies or anything with these results.
Any suggestions? I've tried this twice with the same results.
