"If it can be written, or thought, it can be filmed..." STANLEY KUBRIC
From Encyclopedia PRO
The color temperature of artificial light which is 3,200K on the color temperature scale. Quartz Lights use a tungsten filament, which burns at 3,200K, and gives us this term. Color film for indoor shooting is balanced for tungsten light, otherwise the image would appear orange in hue. If tungsten balanced film is used out-of-doors without a correction filter the image will have a washed-out blue hue.
