[alt-photo] Re: Clearing Up A Few Things About RC Paper Negs for Alt

[Tomas Sobota]

Francesco,

I have never worked with Pt/Pd, but I have used RC paper negs exposed
in-camera for printing gum dichromate. I used the paper negs as they are,
without peeling or anything. It worked for me, with at least two or three
brands of paper (which I don't remember right now). So I suspect that any
possile UV inhibition effect in the paper is corrected simply by a longer
exposure.
