19 Sep 1969TL;DR: An underwater case for cameras whose specific gravity when housing a camera is less than unity and which has support members for supporting the camera within the case so as to deviate the center of gravity of the camera from that of the case toward the front face thereof is described in this article.
Abstract: An underwater case for cameras whose specific gravity when housing a camera is less than unity and which has support members for supporting the camera within the case so as to deviate the center of gravity of the camera from that of the case toward the front face thereof. The case has a rear surface which is colored with a color which can readily distinguish the case in the water. Ordinary cameras can be used for underwater photography and the case housing the camera floats and can be readily recognized under water.
