RE: Lith film

Clay,

I checked it. The link shows an abstract rather then a paper. No process mentioned, no curves.
I believe you saw Pt/Pd print made with PMK processed lith film. I also believe they retain all the subtleties in tone that you
could want for this process. What I hardly believe, is that this was printed without contrasting agents. I want my neg to suit my process. Therefore I need a density range (w/ or w/o stain) adapted to pure palladiotype.
My point is: there is no lith film / developper combination that will provide that 3.2 density range (visible light density).
My tests and curves I received today confirm that.

I really don't agree that the lith film approach is a total dead-end
for making enlarged negatives. I have seen real-life results from
several workers (e.g. Stuart Melvin, Bob Herbst, Michael Kravit) who
are producing long scale pt/pd type enlarged negatives using APHS that
are very fine indeed, and retain all the subtleties in tone that you
could want for this process. Naturally, it takes a little practice and
a lot of care, but dismissing this approach completely is a little
premature. For instance, check out :
