Abstract:
A method of photographing a subject with a foreground and a rearground, the method comprising the steps of:providing a camera with a photoflash projection device comprising: a housing defining an interior space and having an exterior surface; a multiplying circuit for receipt into the interior space of the housing; a lamp, the lamp for engaging the housing, the lamp comprising: an elongated, glass, gas-filled, straight flash discharge tube having a first end and second end, the two ends engaged in gas sealing relation by two electrodes; a reflector surface, the reflector surface adjacent and parallel to the straight flash discharge tube, the reflector surface having a profile defining a curved surface in a plane vertical to a longitudinal axis of the flash discharge tube, a curved surface with a longitudinal axis parallel to the longitudinal axis of the tube; a pair of side reflector plates located at two removed ends of the reflector surface whereby the multiplying circuit engages the tube to intermittently apply a potential difference across the electrodes of the tube sufficient to create a flash discharge therefrom; and aiming the reflector above the rearground and beneath any bounce surface of the subject; and releasing a shutter of the camera triggering the flash discharge tube of the flash device.
