Re: gum negatives redux

I should've been more clear...I'm getting better gum results from palladium negs than using less contrasty negs for gum. My palladium prints print wonderfully with the palladium negs ;-)
This would be a huge advantage for me, in not having to keep track of two different styles of digital negatives.
Now, I'm wondering how the palladium negs will work with tri-color gum...only one way to find out!
