Learning never exhausts the mind

The White Balance setting on cameras and editing software allows changes to the colour balance in your photos, making them warmer or cooler depending on the light conditions you're shooting in. White balance is also used to change the atmosphere in your photo.

White balance is the process of adjusting colour cast so that whites appear white. For example, take a sheet of white paper and place it under an indoor light - it takes on an orange tint. Take that same paper and place it under fluorescent lights it appears much whiter, or even slightly blue. Having the incorrect white balance is responsible for making photos appear very orange when indoors, or photos taken at dawn or dusk appear blue.

Most of the time modern cameras do a pretty good job of selecting the correct white balance profile to use. The most common colour profiles and corresponding temperatures and uses are shown in the illustration below.

White Balance Examples

White Balance Examples

White Balance Modes

null

Auto (AWB) - A simple fail-safe for snapshots, but can vary from shot to shot depending on how the camera meters the scene.

null

Incandescent - Used for domestic indoor lighting and will colour match more effectively, eliminating the orange colour from indoor photos.

null

Fluorescent - for use when photographing under fluorescent lighting, however there are many types and this setting often has many options.

null

Direct Sunlight - Gives neutral colours under midday sun. Often used as a reference for "normal"

null

Flash - Flash guns have a cold feel about them, using this setting warms them up a little.

null

Shade - For shooting outdoors in shady conditions, under blue skies but not direct sun light

null

Cloud - For shooting outdoors in cloudy conditions, overcast with grey skies and a dull light cast

null

K - Some cameras allow manual colour selection from a list of temperatures in Kelvin.

Fixing White Balance

The easiest method is to select the correct colour profile on the camera; however, it may be required to do so afterwards in post processing.

Most image editing packages have a white balance feature which allows selection from a list of presets, similar to on the camera. There is also often a manual mode, allowing you to manually specify what "white" is and what "black" is. From this, it can generate a colour profile curve which can then be fine-tuned. It should be noted that this option is for advanced users as incorrect settings here will have disastrous results.
