Did my first PMK development today and wanted some feedback. Since I have never seen negs from PMK before, they have a greenish brown stain. Haven't printed them yet. They look nice with good detail. Here's what I did:

Ilford 5+ (120) processed in JOBO CPA2+. I used the small tank filled it with 500 ml of stock. Mixed 10 ml of A, 20 ml of B with 1000 ml of distilled water. At 70 deg I processed them for 11 minutes. Did a 1 minute water stop bath; 5 min TF-4 fix; 2 min bath in the used developer and a 20 min water rinse. 20 sec in photo flo. Hung to dry.

Would appreciate any suggestions other PMK users might have. Also have a roll of Plusx 120. Can't find any development times for that. Has anyone used this for their portraiture work? I use Trix and Plus for that. How much developer would one use for the large JOBO tank. The one that holds 6 rolls of 35mm? I know I need to get Gordon's book, but until I do ..well thanks

I use HP5+ in PMK also in 120 size. I don't use a JOBO motorized tank, just the old fashioned flip it over yourself type.

I have found that my film speed is 200 in PMK which produces a film base plus fog density of around 0.10. I develop for 8'0" at 70 deg F with a liter of stock solution, agitate 2x per 15 sec. This produces Zone VIII density of 1.15 which works well on my condenser enlarger.

You'll need to run your own tests because 1) you are using less stock solution than I am 2) the JOBO tank could lead to rapid oxidation and inactivation of the PMK and 3) everybody's equipment is a little bit different.

Definitely get Hutching's book.

Don, watch out that you don't confuse 'stock' solution with 'working' solution! Someone might get some real nasty negatives.
