White balance: In digital camera terms an adjustment to ensure that colours are captured accurately (without any colour cast) whatever lighting used.
Shameless copy and paste:
Unlike film, which basically comes with just two colour balances Ã¢â‚¬â€œ Daylight and Tungsten, digital cameras and backs can be set to a wide range of colour temperature settings. With film, fine tuning can only be done with the use of CC filters in the field (if shooting reversal stock), or at the printing stage (if shooting negative). But all digital cameras have the ability to set the White Balance through the use of presets such as Daylight, Shade, Indoor, Fluorescent, Flash, etc. In some high-end digicams, and most DSLRs, exact Kelvin temperature values can also be set, although you will find that how each camera reacts to being set to 5700 Degrees, for example, will differ.
All cameras have as well an Auto White Balance mode Ã¢â‚¬â€œ where the camera estimates the temperature of the light, based on an integration of what is recorded in the scene. Usually this works pretty well.
If one is shooting in Raw mode it's even easier. There is no colour temperature "baked" into the shot the way it is with JPGs. Instead, the white balance which is set in the camera, either manually or automatically, is simply a "tag" which accompanies the Raw file. The Raw conversion program uses this to display the file, but you are free to set the white balance to any temperature that you wish after the fact.
Most photographers know that the easiest way to get white balance correct is to take a shot of a gray card, or a white piece of paper. Then, when you're sitting at the computer with the file loaded into your favourite Raw converter, simply click on a shot of it taken in identical light to the shot that you want to white balance, and you've got it.
