Hi: A friend of mine is building a circuit camera designed to shoot 12" wide CGP lith film. Its design is that the camera body rotates, while the film is rolled behind a slit. It should be able to take picture of varying widths. It should be finished in a month or so.
I can't wait to see the contact prints it will make :) Gord On Fri, 12 Dec 2003 dain...@aol.com wrote: > Hi Tom, > > I wanted to make a Cirkut camera out of a 2X3 "baby" Speed Graphic but > could not figure out how to spin the camera around a tripod and have the > film sync to it.
