Abstract
An apparatus for exposure correction is provided for use with a camera of automatic exposure control type. An amount of exposure which is determined on the basis of an output from photometric means is shifted by a given correction value toward overexposure or underexposure in response to the operation of a manual operating member. The correction value can be varied either automatically or manually. The correction value can be changed by automatically reading information given on a film or a film container and representing a film latitude, by manually supplying a film latitude value, or by utilizing information representing a film speed which has a correlation with a film latitude. In this manner, a photograph having an improved gradation can be obtained by effectively utilizing a film latitude.
