1. Within a digital camera, method of digital image processing using face detection to achieve a desired luminance contrast, comprising the steps of: (a) identifying a group of pixels that correspond to a face within a digital image; (b) determining first initial values of luminance of pixels of the group of pixels; (c) determining second initial values of luminance of pixels other than pixels of the group of pixels; (d) comparing the first and second initial values to determine an initial luminance contrast; and (e) determining properties of a fill flash for providing adjusted values of luminance for at least some of the pixels of the digital image based on a comparison of the initial luminance contrast and the desired luminance contrast.
