ABSTRACT:
A system for displaying an exposure value in the viewfinder of a camera or exposure meter. At least part of the light which travels through the objective of the camera is used for determining an exposure value which is displayed in a luminous manner at a location displaced from the viewfinder. A reflector receives light from the luminous exposure value display and reflects this light into the viewfinder while the image of the object which is to be photographed is also reflected into the viewfinder so that the camera operator will see in the field of the viewfinder an image of the luminous exposure value superimposed on an image of the object which is to be photographed.
