Abstract
A method of calibrating digital images having pixels with pixel values includes the steps of: exposing a photographic element to form a latent image of a reference calibration target including a plurality of reference calibration patches; exposing the photographic element to form a latent image of a scene; processing the photographic element to form developed images from the latent images on the photographic element; scanning the developed images to produce digital images; measuring the pixel values of the digital image of the reference calibration target to produce a measured value for each of the reference calibration patches; obtaining an aim value and adjustment data corresponding to each reference calibration patch; generating image calibration corrections using the measured values, the aim values, and the adjustment data; and applying the image calibration corrections to the digital image of the scene.
