Abstract:
A process for fabricating a photographic film strip having a pre-exposed first portion and an unexposed second portion for use in a camera in which the unexposed second portion will be exposed as successive frames, the process comprising the steps of:fabricating a master film strip by successively exposing a section adjacent one edge of the film strip to a first image through a frame aperture having one area with a width greater than the width of a frame to be exposed in the camera to form a continuous pre-exposed first section between opposite ends of the master film strip; positioning the master film strip in contact with the photograph film strip including sprocket holes between opposite ends with an emulsion side of each film strip contacting an emulsion side of the other film strip; and exposing only the portion of the photographic film strip in contact with the exposed first section of the master film strip along one edge to light to pre-expose the first portion of the photographic film so that the pre-exposed first portion will extend laterally beyond opposite edges of each frame to be formed on the photograph film strip and the photographic film strip need not be precisely registered when loaded into the camera.
