ABSTRACT:
A photographic illumination system, comprising a first stroboscopic flash tube, for emitting an intense broadband illumination pulse comprising ultraviolet rays; a second stroboscopic flash tube, for emitting a rapid series of broadband illumination pulses comprising ultraviolet rays; an optional filter, within a common optical path of the first and second stroboscopic flash tubes, for filtering a portion of the broadband illumination; and a control, for synchronizing the illumination pulse of the first stroboscopic flash tube with an external trigger pulse, wherein the second stroboscopic flash tube provides an output suitable for use by a human, unaided by viewing accessories, to compose a subject at a distance from the first and second stroboscopic flash tubes, and the first stroboscopic flash tube provides an output pulse suitable for exposure of an image capture medium. Both tubes are preferably manufactured to maintain the same spectral signature by adjusting fill pressure and gas mixture.
