ABSTRACT:
Apparatus which ensures a background providing colored contrast to permit easy legibility of data items recorded on film material is always produced irrespective of the brightness or color of a photographed scene or of the portion thereof adjacent to the data recording area on the film material. In addition the whole area of film material may be made available for carrying the image of a scene when it is required to produce a photograph unaccompanied by data. The data projection system is independent of the taking lens system for the light reflected from the external scene and a movable blocking element moves only into and out of the path of the taking lens system.
