San Francisco photographer Darren Samuelson built his own six foot-long ultra large format camera that uses 14″ X 36″ X-ray film negatives. It took him over six months to complete and the results are quite fascinating.
"I built a great big camera, and figured there might be a few folks who would be interested in the process. The idea started when I read something about people using x-ray film in regular cameras as a cheaper alternative to photographic film. For 10 sheets of the film I normally shoot with, I could get about 125 sheets of the x-ray film. This new film, although cheap, is very fickle stuff, but once you learn all the tricks, it can be just as sharp as most other films, but it really requires special handling."
