Skull and Photographic Superimposition: A New Approach Using a Second Party's Interpupil Distance to Extrapolate the Magnification Factor

CODEN: JFSCAS

Abstract

The photographic superimposition technique requires an antemortem photograph to be enlarged to life size and the skull to be photographed from the same angle as the antemortem photograph. This paper describes how the magnification factor can be extrapolated by measuring the true interpupil distance of a second person and the photographic interpupil distance of the suspect and the second party. A closed-circuit television (CCTV) system is used to determine quickly the skull photographic angle. We believe these techniques are viable and easy to perform.
