I gave a pinhole workshop in Columbus. Three folks attended. Two had body caps for their DSLRs, one had a 120 film camera from the Czech Republic. I used my Zero Image. Two images from the workshop at the Statehouse in Columbus.
Yeah, I think it's more like 6x10, but who cares? No extra charge for the extra length? The problem is that I have to be careful advancing the film, or the images touch! I've learned to adjust! And I use a 6x12 carrier.
