The DC capacitance is of interest for discharge applications like photoflash. A 1&colon;1 mixture is used for photoflash batteries. This allows a high current output with intermittent use, perfect for photoflash use. Those filaments are widely used in mass spectrometers, ion gauges and photoflash lamps in photography. There were several models of photoflash bombs, but most had a similar construction and makeup. Hansen was chosen Miss Photoflash of 1953 by the Chicago Press Photographers Association. Photoflash bombs could be carried for night photography missions. M120 photoflash bombs were used, and possibly practice bombs. Other missions included disruption of enemy sea channels; dropping photoflash bombs and propaganda pamphlets. Photoflash ejectors could be carried in underwing tanks for nighttime photographic reconnaissance missions. Higher voltage photoflash batteries are also made to fire reusable xenon flash tubes. The QuickTake 150 kit also included PhotoFlash software (for Macintosh) or PhotoNow! Capacitors with higher voltages, for example photoflash capacitors, usually containing anode foils with crystalline oxide.
