An apparatus and method for stereoscopic photography in which a direct view camera with a direct view lens is mounted to a support to obtain a direct view camera shot while a reflected view camera with a reflected view lens is mounted to the support in a down-looking camera configuration to obtain a reflected view camera shot without use of a beamsplitter when an interaxial spacing between the direct view camera and the reflected view camera does not cause an overlap between a direct view active optical area of the beamsplitter that would be used by the direct view lens and a reflected view active optical area of the beamsplitter that would be used by the reflected view lens. A reflective planar mirror can be positioned to (substantially fully) reflect light from a surface of the reflective planar mirror to the reflected view lens while a transparent planar glass is positioned to allow light to pass substantially perpendicularly through the transparent planar glass to the direct view lens, both the transparent planar glass and reflective planar mirror having substantially parallel surfaces and being integral or not. Alternatively, the transparent planar glass can be eliminated and a spacer used to adjust the mounting of the direct view camera to the support so as to restore a sight line for the direct view camera. In still other alternatives, either one or both of the direct and reflected view lenses can be replaced with a pinhole lens.
