1. A method for pre-exposing film to an image in registration with a single use camera frame opening, the method comprising the steps of:

  • providing a single use camera having an exposure frame opening;

    forming the opening for shielding a portion of a filmstrip frame from exposure to image bearing light, the opening providing a camera exposure film frame shielded portion sufficient for receiving an artwork image;

    providing an unexposed alignment filmstrip dimensioned for use in the single use camera, the alignment filmstrip for aligning artwork within a portion of the filmstrip;

    mounting the alignment filmstrip within the single use camera for exposing the filmstrip to image bearing light;

    exposing the alignment filmstrip to light sufficiently bright to form a latent image of the exposure frame opening onto the alignment filmstrip;

    developing the alignment filmstrip for forming a frame opening image on the alignment filmstrip wherein the developed frame has a clear portion for viewing artwork therethrough and an opaque portion;

    providing artwork for exposing a first portion of a film frame to the artwork;

    affixing the artwork within an artwork portion as viewed through the alignment film frame clear portion, the artwork portion corresponding to the shielded portion of the covered exposure frame;

    removing the alignment filmstrip;

    mounting an imaging filmstrip within the copy camera for photographing the artwork within the artwork portion, the imaging filmstrip having first and second surfaces, and sprocket holes along edge portions;

    placing the artwork within the artwork portion;

    exposing the imaging filmstrip to imaging light from the artwork thereby forming a frame on the imaging filmstrip having a latent image of the artwork within a portion of the frame shielded by the shield portion of the single use camera exposure frame opening;

    developing the imaging filmstrip;

    providing an unexposed filmstrip having first and second surfaces, the unexposed filmstrip dimensioned to communicate with the imaging filmstrip, the unexposed filmstrip having a multiplicity of sprocket holes along edge portions of the unexposed filmstrip;

    placing the imaging filmstrip in contact with the unexposed filmstrip; and

    exposing the imaging film second surface to light for pre-exposing the unexposed filmstrip thereby placing a latent image onto the unexposed filmstrip and forming a pre-exposed filmstrip, the latent image representative of the imaging filmstrip artwork image, the latent image positioned within a portion of the unexposed filmstrip for shielding by the single use camera exposure frame opening shield portion.
