Abstract
An exposure control method in which an exposure value for a designated or particular original picture is determined using in combination photometric values or exposure controlling characteristic values of a designated original picture and photometric values or exposure controlling characteristic values of at least one other original picture which is weighted with relativity to the designated original picture. With this method, pictures of similar or continuous scenes are reproduced with a uniform density and color. The method may be applied to photographic film, particularly, motion picture films, VTR photographing operations or picture printing operations.
