Nice prints indeed, but "so" clean for paper negatives with handmade pinhole. Maybe he's used a laser-drilled pinhole in there. They give you really sharp images but event with laser-drilled, it's hard to avoid the problem from blur arising from diffraction at the edges of the pinhole hole. Unlike lenses, every pinhole is different and each photographer tends to get very different results depending on their camera system.... Just got this evening the color prints I shot during the workshop and they confirm the "soft-focus" nature of my 35mm pinhole when I use handmade pinholes with that format of film... Great for pictorialist imaging, though...

Ha! my apologies, Dave. Didn't mean to put you down on this. Just quoted the numbers for illustrative purposes after four days explaining to workshop participants what an F/stop actually was and how it worked when you want to get propoer exposures. I think they've picked it up by the end of the 4 days, but they're now probably making nightmares about this crazy pinhole teacher and his F/stop numbers. Anyways, it seems that you've got the killer instinct with your three 1,600 watts flash heads! -:)) Best regards to both, Guy
