A reproduction camera comprises a copyboard (5) with picture (9) which is to be photographed, above which is disposed an objective with a diaphragm (4), possible filters (3), a shutter (1) and a focal plane (11) in which the film is placed. The camera is controlled by an electronic image scanning element (6) which, fully automatically and point by point, scans the copyboard and measures the total light intensity, finds the picture's lightest and darkest points, the picture's position and its dimensions. A further measuring element (2) measures the light intensity immediately in front of the focal plane. One can hereby provide a reproduction camera's digital calculation module with all the information necessary for the setting and the control of the exposure, completely without any mechanical movements or manual effort.
