Like I've always said "What works in my darkroom most likely won't work in
yours!" "And my way works for me you need to find your own
path"...........I'd try the acid clear I know it changes the paper...... no
idea as to effects with zia though. I'd test with just acid clear first to
see if the paper change is what you want that last bath of s.s. and edta
tends to remove some of the color I find objectionable. The paper certainly
prints warmer than anything I've found using pure palladium- if you go to my
web site there is more information on rising and how I get it so warm in the
tech papers. Unlike some they are accessible to everyone.... but reread
the beginning of this post first!
