Inter-Sprocket Area

In the camera used by Zapruder, the aperture opening extended into the inter-sprocket area. The area between the sprockets was not supposed to be seen during normal projection. The aperture opening in the sprocket area extended vertically beyond the normal frame area, so that there occurred superimposition of images. In the sample using Z330, the motorcycle escort in the foreground was partially exposed, along with the bumper of the limousine.
