You shot 2-1/4 right? Those scans should hold for software manipulation. Lord knows you have a ton of resolution. What is your intended final print size?
I don't know about you, but I didn't bring a flashlight to the shoot. I would have had no way of setting a perspective control lens because I couldn't see anything on the lens barrel.
6 x 4.5. I always scan at 4000 dpi-->huge files, plenty of resolution. I have made up to 17 x 22's (Epson 4000's max) with no grain, no pixelation...fabulous prints. I think I could probably go even larger if I had the printer to do it on.
It was much darker in there than I'd anticipated. Of course I'd only seen Michael's website images of the place, and of course they made the place seem much brighter. I coulda used that flashlight for sure, and I would not have been able to figure out a new PC lens in near-darkness, to be sure.
