Abstract
PURPOSE: To perform correction of an exposure control circuit and achieve the optimization of exposures by comparing the output of a photometric circuit which measures the difference in reflection factor between shutter curtain plane and film plane and the output of a photometric circuit which measures the reflected light from the film plane and shutter curtain plane.
