Hello Sandy, My experience with VDB is limited. I got started on
Kalli/VDB/Silver when I wanted 11x14 and 16x20 cloth prints. Platinum
(Palladium) was simply too $$. On cloth VDB gave me a significantly
lower Dmax (visually) so it was discarded as an option for THIS project.
I've since done some work with Kalli on paper, as I had all the
chemicals for Kalli I didn't retest with VDB on paper.
After I wrote about my Epson 1200 and "darn good inks", I've had a
terrible day. Everything looked too dark and flat. Should have guessed
earlier, my last batch of ink came in "new packaging". I worried about
that, but printed a few photos on regular paper and the colors were
fine...... However they don't make the same neg in UV light!
I've wasted a fair bit of $$ Pictorico and will have to redo a few
curves :-(
I wish people would stop changing my materials!
