What is your processing strategy for the tech pan? I built a K mount back for my view camera. I haven't really given it much use, but I bet it would be good for this type of work. Even with the throat depth, I expect a person could get enough front tilt to correct the depth of field. About the only useful information one can get from 1000:1 TOC tests (those are the ones that people bandy about as "this film will resolve 200 lpmm") is that it is, indirectly, a report on granularity, even though the working resolution is probably closer to 1/3 of the 1000:1 resolution. I recall that Tech Pan scores way higher than T-Max in the lab, it's nice to see that translates to the real orld as well. I always have liked Tech Pan, though I have never been able to master it. It looks like you have it figured out quite well. William Robb
