Abstract
Quality control has long been practiced, diligently, in the photographic manufacturing, motion picture, and aerial reconnaissance/mapping industries. Manufacturers spend large sums of money on quality control tests and analysis in each step of the manufacturing process including the selection and processing of the gelatin, the testing of each constituent chemical, the testing and certification of the final product, and the testing of the containers used for packaging. Between the first step in the manufacturing process and the final packaging many quality control checks are carried out. This assures that the product, as it leaves the manufacturer's warehouse, meets the specified criteria in terms of speed, contrast, shelf life, fog levels, uniformity, etc.
