ABSTRACT:
Submarine photography apparatus includes a camera to record scenes in a selected sector forward thereof; a source of light having a wavelength in the range between about 650 and 700 nm. designed to project from a position lateral of the camera a conical light beam so that it intersects the sector; and a system of optical and electronic elements to detect and measure the intensity of reflected light from a photographic subject within a conical volume that has its apex lateral of the camera and extends toward the sector to intersect the light beam so that the intersecting peripheries of the light beam and the conical volume substantially define the sector. Methods of photographing with the apparatus include flashing a strobe light and exposing the camera when the system measures an intensity of the reflected light above a predetermined minimum value within the sector.
