If so, please remember that your 15"X15" camera will have a film diagonal length of more than 21" so that you will have vignetting of the corners of the film. If that is accepable to you, then good. If not, you will either have to design a smaller format camera or get a lens that throws a larger diameter circle. You might be able to get away with this lens stopped down because, with most lens designs, the image circle gets bigger as you stop down the lens. CHEERS!

I have an idea of how to build the film holder for it but am unsure of the best approach for the actual body and bellows (which I have no money to buy and will have to shimmy together). Does anyone have any suggestions on the basic design and or any online plans for such a camera? I'm hoping to get it built in the next two weeks as I'm enrolled in a semester of palladium printing... (exciting!) Thanks! -Zev __________ NOD32 3412 (20080903) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com
