I found a while ago a woman who have done some weddings and some others stuff with pinhole cameras, but I forgot her name.

Check out Renee Creager O'Bren. She's a coworker of mine, and has some work in NY MoMA's pemanent collection,among other places. She also did her doctorial thesis on pinhole, which resulted in a commercially available treatise of some 600 pages. To be honest,I haven't read it - pinhole's not my thing. But she's an excellent teacher, so I can only assume it's extremely informative. I also know she was shooting a lot of weddings around that time, so I wouldn't be surprised if she talks a little about the potential commercial uses.

Good luck!
