Strobe light photographing system

A camera which controls a strobe light to execute preliminary emission before main emission, comprising:

• a unit which has a plurality of regions for splitting a field into a plurality of fields and performing photometry of light reflected by an object to be photographed by preliminary emission in the plurality of regions;
• a unit which determines precision of a distance information from a interchangeable lens mounted on the camera body;
• a unit which calculates a proper photometry level from the distance information;
• a unit which calculates an identification level for identifying an abnormal reflection region on the basis of the proper photometry level and a distance precision set in accordance with a determination result of the precision;
• a unit which compares photometry values of the plurality of regions out of the plurality of regions with the identification level, thereby determining an abnormal reflection region;
• a unit which measures a photometry values of reflected object light in the plurality of regions out of the plurality of regions from which the abnormal reflection region is excluded;
• and
• a unit which controls an main emission amount by the photometry values of reflected object light.
