I want a 7x17 camera. I think that format makes the coolest looking contact prints. I am gonna donate my Kodak 2d 5x7 to the project of making one. All I really need to do is make a new back standard and a focus back. Then, of course, I would need a new bellows and some holders and a lens. ugh???....Maybe I won't, 'cause that is a lot of money. Maybe I will just make some images with the 4x5 and make contacts from enlarged negs.
