Abstract
PURPOSE: To restrict the shutter second without deteriorating a photosensitive material by introducing a proper quanity oft bias light during photography into such a light receiving element of a system for photometry of the light feflected from the film surface as is operative to indicate in advance the exposure time second before the photography.
