The problem is, having never made a palladium print, I don't know what a
negative targeted for palladium would look like. My ultimate goal is to
make platinum/palladium prints out of 150 negatives that I have not yet
processed, and I thought I would start by doing some experiments with
cyanotype just to get the coating thing down, etc. But maybe I should not
process all those negatives on the basis of the cyanotype "proofs", but
rather, play with cyanotypes a while with other negatives, then work out a
development time for palladium separately.
I am not planning to do the new cyanotype thing because of the extra toxicity.
