Abstract
A method for processing and laser ablation marking an imagewise exposed motion picture photographic film element which comprises a support having on a front side thereof one or more image-forming units comprising at least one light-sensitive silver halide emulsion layer is described, comprising processing the film to provide a developed photographic image with at least 100 mg/m2 of retained silver halide, and subsequently laser ablation marking the film to selectively ablate portions of the image forming units from the support.
