Abstract
This invention relates to an apparatus and method for providing calibration of photographic media. More particularly, the method and apparatus are based on measurements of areas of minimum optical density of a given photographic medium. Such measurements, when combined with reference optical density vs. exposure calibration data for related photographic media, provide an estimate of the optical density vs. exposure relationship of the given photographic medium. The method and apparatus of this invention are especially applicable for the calibration of photographic media used in hybrid imaging applications.
