I thought I would not give any more comment but I'd like to correct your massage.
You might be too upset to remember what you wrote.
"In fact, I would decline to use a P1 back even if it was free - it completely ruins my creative process, I would hate every second of the experience, and the upside in imaging results is debatable. Had I used my 8x10 at the Carmel workshop, I would have had a handful of truly amazing exposures, as opposed to dozens of crappy, noisy, bulky files. Sure, it would take a bit of time and effort in post including development and drum scanning, but there would be a real contribution to my portfolio, whereas what I got from the P1 backs (60 MP CCD and 100 MP CMOS) was frankly utter crap".
