PURPOSE:To finish a print with reproducibility by detecting the difference between the output of a photometry means and the output of a control value arithmetic means, and outputting and recording information regarding the difference. CONSTITUTION:A difference detecting means 40 detects the difference between a control value EV outputted by the control value arithmetic means 30 and a light value LV outputted by a photometry means 10, i.e. exposure quantity error delta and outputs it to an information recording part 50. The information recording part 50 records the exposure quantity error delta in an information storage part 60. Here, when the light value LV is within an exposure associative control range, the light value LV and control value EV becomes equal to each other, a film is exposed properly, and the exposure quantity error delta=0 is recorded. When the light value LV is not within the exposure associative control range, the light value LV and control value EV are not equal and excessive or deficient exposure is performed, but delta is recorded as the exposure quantity error. Consequently, the print with excellent reproducibility is generated with good efficiency.
