Hang on a minute, chaps, we're all missing something here: of course
bleaching a straight neg and redeveloping in PMK will intensify! A good PMK
neg tends to be thinner than an ordinary neg, but its overall density is
determined much less by the developer than the development time; allowed
enough time to act, it will develop all silver that is developable. With a
bleached neg, it will therefore redevelop all of the original silver within
10, 15 minutes or whatever, AND add its stain to it. Result? An
intensified neg!

This still doesn't explain Sandy's results. As a matter of interest, Sandy,
why is there bromide in your bleach?
