I have been making pt/pd prints from:
4x5 Ilford HP5
enlarged negatives on x-ray duplicating film
scanned negatives on Pictorico OHP using Dan Burkholder's software and with PhotoShop and my own curve
I've gotten very nice results with each and although I am partial to the film route some negatives requiring more than just simple editing do work best with the digital manipulation. I keep it as simple as possible and print the pt/pd on paper and/or vellum which I have backed with 24c gold leaf or sterling silver leaf as per Burkholder's technique.
I have never taken a workshop and far from a computer maven I managed to get results.
