What is tungsten white balance?


White balance is the process of removing unreal colours from a scene or object. In simple, things which we see as white with our eyes should also be captured as white in photo. If they are captured with varying colour cast, then some colour adjustments should be done in the camera so that they are captured in white. This adjustment is called white balance adjustment.

The white balance of a camera takes in to account the colour temperature of a light source, which means relative warmth or coolness of white light. The symbols below show some of the white balance settings available in a digital camera.



The approximate color temperatures of lighting sources are given below.


    Incandescent—3,000° K

    Fluorescent—4,200° K
    Direct Sunlight— 5,200° K
    Flash—5,400° K
    Cloudy—6,000° K
    Shade—8,000° K

White balance can also be adjusted to capture strange creative images. One such setting is the tungsten white balance, which helped me to capture the blue tones in the photographs displayed here. The tungsten lighting settings, assumes a colour temperature of around 3,200K and is suitable for most tungsten lamps that normally emit a yellow light. It is the equivalent of an 82-series blue filter used with a film camera to correct for the same colour cast. Also a photograph taken at day can be made to look like it was taken at night by setting the tungsten white balance and slightly under exposing the shot.
