Pinhole cameras use a tiny pinhole as their aperture instead of a lens. Fran?s Besson created this cam to take a 240 degree panoramic picture. The cam aperture slot rotates on one axis while the film rotates on a separate axis. The 8×20″ film is attached to a large drum mounted to the second spindle. The exposure length can be 18, 6, or 3 minutes depending on the voltage supplied to the drive motor.
