ABSTRACT:
When an electric shutter camera is set at a bulb photographing mode, which camera has an electro-magnetic release which places a photo-sensing circuit in an active state by a photo-sensing switch associated with a first stroke of a shutter button and provides shutter release by a camera-initiating switch associated with the second stroke of the shutter button, shutter release is performed by the camera-initiating switch and at the same time, the retention of a shutter follower screen is released in association with the photo-sensing switch to complete bulb photographing action.
