Abstract
In a method of determining printing exposures, an original image to be printed is divided into at least two image extents, namely, a principal subject and a background, from each of which at least one image characteristic value is obtained based on the color densities thereof. On the basis of the obtained image characteristic values the proper exposure is determined for obtaining prints of proper densities. The proper exposure is performed by basic exposure control in which the basic exposure is obtained from the image characteristic value, or its artificially weighted value, of the principal subject image extent, and by color correction whose amount is determined either from the characteristic value of the background image extent or from the characteristic values of the both image extents.
