The Cine Flash: A New Lighting Equipment for High-Speed Cinephotography and Studio Effects
A new form of portable lighting equipment is described which has been designed especially to meet the needs of the high-speed cinephotog-rapher who is always faced with the difficulty of obtaining sufficient light. Two compact-source mercury cadmium lamps are operated in series at their normal wattages of 1 kw, and are then flashed at 3, 5 or 10 kw for 5, 2 or 1 sec. The equipment consists of a control unit and two lightweight lamp-houses. — The light output is sufficient for color photography at speeds up to 3000 frames/sec, or for black-and-white photography with small lens apertures to give considerable depth of focus. The flash may be triggered from a microswitch or from a camera switch. The steady light output from the lamps is sufficient to arrange and focus the subject.
