The device has a controller that determines the exposure device setting region, depending on format of the original region, and drives the exposure device The device has an exposure arrangement (25) with an output light beam that passes over a defined path to a light sensitive medium (16). There is a detection arrangement (12,14) for detecting the format of an image region of the photographic original (10) containing the information to be illuminated. The exposure arrangement contains several adjustable position regions, with which the intensity of the light beam can be adjusted by region, and is fixed in the beam path (24). A controller (14) determines the setting region for the exposure device, depending on the format of the original region, and drives the exposure device to set the intensity of the light beam to be output in the defined position region.
