I have a folder of them on top shelf of a closet -- done about 8 years ago
and no longer in the memory bank.  I was TRYING to change the color by
additives. That was iffy, though as I recall some gallic acid added had a
lengthening (& fogging) effect, as well as darkening. I noticed
differences of scale on different papers, though that WASN'T what I was
looking for, & tests weren't controlled for that -- so wouldn't cite them
now (even if I had strength & time to dig them out). Also, needless to
say, the papers have changed, and your conditions otherwise won't match
mine....

I do however feel confident in saying that the paper DOES change contrast
range.  (And if it does in cyanotype, which it does, why not in VDB???)
