For some reason I found this in my postpone file.... maybe the doorbell
rang,,,, anyway, Sandy, if you're still trying to increase contrast in
VDB... I wrote (FWIW)....

====================
There are I think 3 [VDB formulas in P-F #1], one that didn't work AT ALL,
one that sort of worked but wasn't very good, and the regular classic VDB
we know. That last is what I refer to -- but in some sources (which I do
not bring to mind), the part about "contrast control" with dichromate came
with it.

My folder on VDB is on a high shelf, & to get it down disturbs a lot of
asbestos particles, & other fallout from WTC (not to mention the usual
dust mites and mold spores), but *I believe* I exposed to the max, that is
to the point that the bottom steps blocked up. I therefore assumed that
the cliff at the other end was intrinsic, not to be overcome by more
exposure (although Sandy says didn't find that !!!).

-But if you want to increase contrast in the negative, I found that
chromium intensifier followed by selenium toner 1:3 gives the biggest
increase in neg density, also red color which is another filter, and quite
a jumpl A very brief Farmer's reducer before the intensifier can weaken
highlights for even more contrast.

best,

Judy
