Abstract
A photographing apparatus employs a real time photometry technique, and includes a central processing unit to which information concerning the characteristic of a film such as a film speed and other information relating to photographing conditions are supplied through input means. The central processing unit selectively controls the connection of integrating capacitors in an integrating circuit on the basis of such input information, and accurately derives an expected exposure period and the remainder of the exposure period. Also, a display of various information is permitted.
