Abstract
An underwater camera which comprises a shutter release button having an elastic construction that permits the shutter release button to be manually depressed to initiate shutter opening and to be increasingly depressed because of increases in the water pressure as the underwater depth of the camera is increased, and an underwater depth gauge that indicates increases in the underwater depth of the camera, is characterized in that the underwater depth gauge is coupled with the shutter release button for the underwater depth gauge to indicate increases in the underwater depth of the camera in accordance with increases in the depression of the shutter release button.
