Abstract
A method of locating a reference calibration patch on a photographic element, that includes the steps of: exposing the photographic element to form a latent image of a reference calibration target having a two dimensional barcode symbol with a finder feature and a reference calibration patch having a known spatial relation to the finder feature of the two-dimensional barcode symbol; processing the photographic element to form a density image from the latent image; scanning the density image to produce a digital image; locating the finder feature of the two-dimensional barcode symbol in the digital image; and locating the reference calibration patch relative to the finder feature in the digital image.
