ABSTRACT:
An improved exposure control apparatus for use in a camera having a shutter mechanism utilizing a setting member with first and second positions corresponding to first and second exposure time setting positions of the shutter mechanism. A spring linkage is provided to urge the setting member towards its first position. The spring linkage, upon manual movement of the setting member to its second position, cooperates with structure within the camera to releasably retain the setting member in its second position. A release member, actuated by the preparation of the camera for the next exposure, releases the spring linkage simultaneously with increasing the restoring force exerted on the setting member by the sprink linkage.
