The electronic shutter of a "through-the-lens" type photographic camera is adjusted to compensate for exposure factors such as the speed of the film in use, and the aperture of the camera lens. The camera is of the type that includes an integrating circuit having a first light-sensitive photocell receiving light through the camera lens, and memory and exposure control circuits each respectively including second and third photocells receiving light directly from the object to be photographed.
