Bob,

I'll have to try more papers. A couple of months ago I did some testing
of cyano using your formula of 2 A to 1 B, and got very rich, deep blue
prints, but with way too much contrast for even my softer Pt/Pd
negatives. It looked more suitable for a straight silver negative in
fact, though I didn't get to try that. I'll try some more tests and see
if paper choice will control the contrast.---Carl
