Abstract
This invention relates to a printing system which makes use of a color exposure determination algorithm. If the printing system permits operator controlled reprinting, then the algorithm's coefficients may be optimized by reprinting negatives using exposures that have been precisely corrected by the operator. This invention teaches that a most efficient way to select the negatives for reprinting is to chose those which lie in two ranges of the 'hat' statistic for any or all of the color exposure determination algorithm equations used to make the print. It also teaches how to automatically re-optimize the algorithm coefficients on a periodic basis using data collected automatically during the reprinting operation.
