An exposure time control circuit for a camera includes a level selecting circuit between a light measuring circuit and a memory circuit to have a selected output memorized in the memory circuit. The level selecting circuit is provided with two inputs, one of which is the output of the light measuring circuit indicative of the scene brightness and the other of which is the output of a maximum exposure time output source indicative of the maximum exposure time acceptable to the camera. The memory circuit memorizes the output selected by the level selecting circuit which output indicates a shorter exposure time between the two.
