Abstract
Abstract A PHOTOGRAPHIC STUDIO LIGHTING SYSTEM COMPRISING A PLURALITY OF LIGHTS (PREFERABLY STROBE LIGHTS) INCLUDING TWO FILL-IN LI GHTS ARRANGED ON OPPOSITE SIDES OF THE CAMERA, AND A MAIN, OR MODELING LIGHT MOUNTED ON AN OVERHEAD BOOM THAT IS SWINGABLE ABOUT A VERTICAL AXIS LOCATED DIRECTLY ABOVE THE SUBJECT. OTHER LIGHTS, SUCH AS HAIR HIGH-LIGHT AND BACKGROUND LIGHT, MAY ALSO BE INCLUDED. A SWITCH ACTUATED BY MOVEMENT OF THE BOOM PAST THE AXIS OF THE CAMERA LENS CAUSES THE FILL-IN LIGHT ON THE SAME SIDE OF THE CAMERA LENS AXIS AS THE MAIN LIGHT T BE INAC- TIVATED, AND THE FILL-IN LIGHT ON THE OPPOSITE SIDE OF THE CAMERA TO BE ACTIVATED. THUS, WHEN THE MAIN LIGHT IS ON THE RIGHT-HAND SIDE OF THE SUBJECT, THE FILL-IN LIGHT ON THE SUBJECT''S LEFT-HAND SIDE WILL BE ACTIVATED, AND THE FILL-IN LIGHT ON THE SUBJECT''S R IGHTHAND SIDE WILL BE INACTIVATED. PRESSING THE CAMERA SHUTTER RELEASE CAUSES THE OVERHEAD MAIN LIGHT AND THE ACTIVATED FILL-IN LIGHT TO FLASH, AS WELL AS ANY OTHER LIGHTS THAT ARE BEING USED.
