Estudio de la Circulacin en el Caribe Mexicano

This disclosure relates to performing proper strobe light photographing which is almost free from the influence of the object reflectance and an autofocus detection error. This disclosure includes a first calculation unit which calculates first photometry data on the basis of a photometry value obtained by a photometry unit for measuring light reflected by an object to be photographed by preliminary emission, an object distance detection unit (# 120 ) which detects object distance information, a second calculation unit (# 121 ) which calculates proper second photometry data corresponding to the object distance information, a third calculation unit (# 122 and # 123 ) which calculates third photometry data on the basis of the calculation results of the first and second calculation units, and a control unit (# 124 to # 126 ) which controls an main emission amount and performs strobe light photographing on the basis of the calculation result of the third calculation unit.
