ABSTRACT:
A system and method for scanning a photographic film using a scanner automatedly identifies the film as either a positive or negative and controls the scanner settings to perform the scan accordingly. The method includes performing a pre-scan of the film, sampling a color density of at least one location of the film, comparing the color density to a standard range indicating an orange bias for the at least one location, and setting the scanner to treat the film as a negative if the color density is within the standard range and to otherwise treat the film as a positive.
