Abstract
A method for controlling the contrast range of the image recording light falling on an image recording medium by means of control light coupled into the optical path of the image recording light, which is composed of several base colors whose brightness is adjusted independent of each other, is provided. The brightness at least of those base colors of the control light is varied, whose dynamics in the recorded image go beyond the admissible dynamic range.
