ABSTRACT:
A single flash discharge tube system is provided that is capable of emitting artificial light of a controlled and variable spectral output to compensate for photographic film color variations and/or extremes in scene color temperature. The flash tube contains a mixture of two or more gasses with each gas in the tube having a different ionization potential. When ionized, each has or combination thereof produces light having a different spectral output. The ionization of each gas is controlled by a trigger voltage applied to the flash tube in accordance with a code on a film container indicative of the color balance of film contained therein and/or sensing apparatus that determines scene color temperature.
