Tungsten is 3,200K; it is the color temperature of artificial light on a color temperature scale A tungsten filament is used for quartz lights. Quartz lights burn at 3,200K, which is how the term originated. If one is shooting film inside, one should use color film that is balanced for tungsten light. If this is not done, the resulting image will take on an orange tinge. Similarly, a correction filter should be used for tungsten balanced film when shooting outside so the resulting image will not appear too blue.
