  2. Tungsten film - Wikipedia

    en.wikipedia.org/wiki/Tungsten_film

    Tungsten film was developed for photographers who use tungsten lights, also known as photofloods, which have a much lower color temperature than daylight, at 3200 kelvins or 3400 kelvins. It also renders colors more accurately than daylight film under ordinary household incandescent lighting.

  3. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    Since fixtures using discharge type lamps produce a light of a considerably higher color temperature than do tungsten lamps, using the two in conjunction could potentially produce a stark contrast, so sometimes fixtures with HID lamps, commonly producing light of 6000–7000 K, are fitted with 3200 K filters to emulate tungsten light. Fixtures ...

  6. Tungsram - Wikipedia

    en.wikipedia.org/wiki/Tungsram

    The name "Tungsram" is a portmanteau of tungsten (/ ˈ t ʌ ŋ s t ən / TUNG-stən) and wolfram (/ ˈ w ʊ l f r əm / WUUL-frəm), the two common names of the metal used for making light bulb filaments. Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and ...

    en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

    Similar to fluorescent lights, HMIs present problems with color temperature when used for film or video lighting applications.Unlike incandescent-lighting units, which are blackbody radiators limited to a theoretical maximum of 3680 K (the melting point of tungsten), HMI lamps, like all gas discharge lighting, emit the emission spectral lines of its constituent elements, specifically chosen so ...

  8. Color correction - Wikipedia

    en.wikipedia.org/wiki/Color_correction

    Sunlight at 5600 K, for example, appears much bluer than tungsten light at 3200 K. Unlike a chromaticity diagram, the Kelvin scale reduces the light source's color into one dimension. Thus, light sources of the same CCT may appear green or magenta in comparison with one another. [ 1 ]

  9. Photoflood - Wikipedia

    en.wikipedia.org/wiki/Photoflood

    Photoflood lamps are a type of incandescent light bulb designed for use as a continuous light source for photographic lighting. [1] The filaments of such lamps are operated at much higher temperatures than is the case for standard, general lighting service lamps. The result is a brilliance of light much higher than the lamp's wattage rating ...
