Abstract
A method is taught for automatically adjusting the balance coefficients of printer exposure determination algorithms based on an examination of the corrections made by the operator when reprinting negatives from unsatisfactory prints. The adjustment is based on the average correction and the standard deviation of the corrections made to each balance coefficient of the exposure determination equation.
