What is Linear Strip Photography?
Normally the film in a camera is fixed behind the lens. Now imagine the camera is stationary and the film moves horizontally behind a narrow slit behind the lens at a constant rate. The objects in front of the lens travel in the opposite direction as that of the film. As the image of the traveling objects record on the moving film, the image will be recorded as if camera had panned the objects as they moved by. If the image of the objects matches the speed of the film the image will record sharp. Objects that don't match the speed of the film will appear smeared. Since the background doesn't move it appears as one long streak.
Severally years ago I got the idea of modifying a Canon AE-1 camera and its associated motor drive to a linear-strip camera. The camera's focal plane shutter was removed. The drive assembly was modified to direct drive. Two small sheets of exposed and processed litho film were added to make a slit where the light could pass through. The circuit board on the motor drive was also removed. The two leads from the motor were then attached directly to the on/off switch. This now controls the film transport directly instead of by the shutter release. When the film is expose, the motor drive is switched on and the lens cap is removed as the objects pass in front.
