ABSTRACT:
A photometry system for a camera has a finder optical system for receiving light reflected by an object and for forming an image of the object on a finder field, the image corresponding to an image that is formed on a film surface. The photometry system also includes an indicator for projecting a predetermined image onto a predetermined area of the finder field: a photometric sensor that detects a brightness of the image formed on the finder field; and a controller which inhibits the indicator from projecting the predetermined image onto the finder field when the photometric sensor is detecting a brightness of a portion of the finder field which includes the predetermined area.
