ABSTRACT:
A camera is provided which includes a backlight judgment section which determines whether the photographic scene is backlit by comparing the average luminance of the entire photographic screen obtained by photometry with the luminance of the main subject at a distance-measuring point selected by distance measurement. The camera performs suitable exposure control accompanied by illumination, such as supplementary light, at the time of exposure in a photographic scene where the main subject is against light.
