Just got back from a WONDERFUL photo trip to Angkor Wat w/ my 8 x 10 and have 70 + sheets of Tri-X, HP5+, and Bergger film that I hope to process in Pyro for pla tinum printing. I've been using Pyro for negs for silver printing up until now, but am hoping to get started in platinum now (hence the experimenting with thre e different films, as I gather Tri-X has advantages over my usual HP5+ for Pt/Pd ). I have more than one copy of many of the best shots, so I'm able to do a lit tle experimenting without risking once in a lifetime shots. Any suggestions for first approximation concentrations and developing times/temps for any of these films in Pyro to produce negs for Pt/Pd printing? The times suggested in the We ese/Sullivan book mostly relate to Rollo/Pyro, and those they suggest for Tri-X for tray processing (which is what I use) don't seem that different from what Hu tchings suggests for negs for silver printing. I would expect the times to be c a. 50% longer.
Also, any personal experience with using the same neg for silver and Pt/Pd when processed in Pyro? This is a claim I have often heard made, and would love it if it were true.
Thanks in advance for any suggestions. Feel free to email if you have any quest ions about Angkor Wat, LF in Cambodia, etc. Truly one of the world's most amazi ng sights!
Thanks,
Nathan
