The Abelson Scopeworks Omniscope is an anamorphic pinhole camera. It provides a bizarre 360 degree view.. The medium format negative is several inches long. The characteristic black bar near one edge is a roller that helps hold the film in place. An interesting thing to do with these images is to apply the Photoshop Polar Coordinates filter. Flipping the image vertically and then wrapping it with Polar Coordinates will yield a different result.
