An apparatus for indicating the contrast range in a scene to be photographed arranged to be situated within the field of view of a viewfinder of a camera. The apparatus includes a plurality of matching fields of respectively differing gray scale reflectance and a light source for illuminating the matching fields to an extent substantially similar to that of the scene to be photographed. By comparing the dark and light areas of the scene with the matching fields, a photographer is able to directly determine the contrast range of the scene and, if necessary, to adjust the same for the desired purpose.
