Abstract

Calibration targets (70) for use with digital cameras (24) comprise black (72) and white (74) target areas to which digital cameras are exposed simultaneously to provide proper settings for highlight and shadow sensitivity prior to making a digital photograph. In addition a white or gray (76) neutral target area, without color bias, is provided, to which the digital cameras are exposed to provide desired settings for color balance prior to making digital photographs. In one embodiment of the calibration target (70), the black (72) and white (74) target areas are on one side of a panel (101) and the white or gray (76) neutral target area is on the other side of the panel (102).
