A fun camera provides precise registration of a latent image within a film frame with subsequent images placed on the filmstrip through exposure of the filmstrip within the camera. Rolls of film are pre-exposed with the latent image of artwork positioned within film frames. Masks are provided for insertion of the camera frame opening for shielding that portion of the film frame which contains the artwork latent image. The art work is placed onto the pre-exposed filmstrip using an imaging filmstrip formed in a continuous loop. The continuous loop having multiple artwork images thereon is rotated while a portion of the filmstrip is in contact with a portion of the bulk film for transferring the artwork image from the filmstrip to the bulk film. The bulk film is advanced while a light source exposes the film when in contact with the filmstrip. The pre-exposed bulk roll of film is punched at preselected sprocket holes corresponding to the filmstrip length for providing a reference sprocket hole within each length of film cut from the bulk roll for loading within canisters for use within the fun camera for double exposure of the film and placement of a second latent image in juxtaposition with the artwork. Improvements to the fun camera film advancing mechanism permits precise movement of the film and indexing of the film using a sprocket hole count for providing improved registration of the multiple images juxtaposed within the film frames.
