When people mismatch their film and light source, they often don't like the results at all. But if you are aware of the effects of mismatching, you can use these color alterations to your advantage. Scenes under tungsten lighting that are photographed on daylight film may resemble outdoor scenes shot at dawn or sunset. The warm light enhances flesh tones, creating a healthy glow. Scenes with heartwarming potential, such as a family get-together in the living room, are further enhanced by the warm orange glow produced by using daylight film indoors at night.
Tungsten film exposed under daylight conditions produces cool, bluish tones.
This is because the film is manufactured with a strong blue bias to compensate for the orange of tungsten lighting. The bluish rendition can create moods from tranquility to storminess. The blue cast of tungsten-balanced film can enhance foggy, misty scenes, or convey a feeling of extreme cold. One of the most interesting applications for tungsten film is in photographing cities at twilight. Blue tones in the afterglow of sunset are very intense, and the orange tones appear more neutral.
