PMK & Film Development Times

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

Now that I'm a bit closer to obtaining PMK chemicals in Australia, can anyone share their experiences with developing T-Max films (or any other) in PMK? Is it suited to developing T-Max 3200? What about pushing film (I'm a bit partial to exposing T-Max 400 @ 1600).

Developing times?

T-Max 100 EI 64 13M 70 deg F T-Max 400 EI 400 16M 70 deg F T-Max 3200 EI 3200 18M 70 deg F

You should read Gordon Hutchings' THE BOOK OF PYRO.

You can get maybe an extra 1/2 to 2/3 stop if you add .1 gram of Amidol/liter of working solution. I don't think PMK is really suited for push processing.

I tried some Delta 3200 at EI 800, and it looks like about 15M at 70 deg F in the standard PMK formula.

I develop TMY in PMK for 15 1/2 min @ 68 degrees. Pyro will produce too much grain when 'pushed.' XTOL is the best developer I've used for pushing. TMY should be exposed at EI 320. As for adding Amidol, I don't recommend it. It increases the activity of the developer and adds contrast, not real 'speed.' In addition, it tints the greenish stain of the pyro negative a purple/black; kind of defeats the whole purpose.
