Abstract
A method for producing copies of photographic originals, wherein an original is scanned regionally. With the aid of measurement data thus obtained, a decision is made in a test step, on the basis of specified criteria, whether the original is worth copying or not. On the basis of this decision, the particular original is or is not copied onto photographic copy material. In the test step, the scanned original is assigned to at least one of at least three categories of originals; namely a first category which includes originals that are unequivocally worth copying, a second category which includes originals that are unequivocally not worth copying, or a third category which includes originals that are neither unequivocally worth copying nor unequivocally not worth copying. Both originals assigned to the first category and originals assigned to the third category are copied onto photographic copy material, and the copies of originals assigned to the third category are specifically identified as belonging to that category and are not included in calculating the price for processing the customer's order.
