PMKPyro compensation - What problem am I looking for ?

from doug mcfarland (junquemail222@yahoo.com)
I'm the sort of person that likes to see-for-myself that some process doesn't work (assuming it's safe to do so :-).

I've been experimenting with compensation development with PMK Pyro, with agitation intervals up to 2 minutes. Visual inspection of the negatives shows no problems, but I’ve not printed one yet. I might also add that I’m developing 5x7 sheets in a sealed container and use an unorthodox agitation technique of what I call shogging. This is a single hard up-down shake of the container followed by a period of complete rest – similar in concept to gas bubble burst.

If compensation development isn’t possible, how do the negatives fail? I though I might see uneven staining. My test negatives have large areas of continuous tone, which I thought would highlight any uneven development.

So the question is, has anyone even seen PMK Pyro compensation failure, and what does it look like? Any first hand experiences?

TIA – Doug
