ABSTRACT:
A processing apparatus performs a pre-shooting to beforehand photograph a camera subject for a light metering through controlling a camera. Image data representative of a pre-shot image of the object formed through the pre-shooting is subjected to a reduction processing by a camera control, and then transmitted to the processing apparatus. The pre-shot image is displayed on a predetermined area of a display unit. Area information representative of a photometric domain in the pre-shot image and a photometric method is determined in accordance with operational information of which the processing apparatus is formed by an input device. An exposure value is calculated from image data representative of the pre-shot image on the basis of the determined area information. Exposure information representative of a shutter speed and a stop corresponding to the calculated exposure value is formed. The image of the object is again photographed by the camera on the basis of the formed exposure information and the control of the processing apparatus.
