What is White Balance?

White Balance is a setting that enables your camera to record images that have a natural looking colour. If we get this setting wrong or just don’t do it at all then depending on where and when we are filming we could get images that will have a strange colour cast - usually they will be too red or too blue.

So why does this happen?

All light has a colour temperature - it's called a colour temperature because it shows itself as a colour tint. Electric and Tungsten bulbs like these shown here have a reddish tint.

We say they have a warm temperature.

The exact colour of red or orange tint depends on the bulb. Some will show more orange or red than others. The less powerful the bulb the more orange they will look. But also the same bulb can have varying temperatures if a dimmer is in use. As it is dimmed the light becomes less powerful and therefore the colour temperature will be hotter and the colour tint more red or orange.

On the other hand, daylight creates what photographers call a COOL image because bright daylight makes everything look more BLUE or cold. And just to complicate things further the Sun’s temperature varies throughout the day, or if there’s cloud or clear sky.

This is not something you, as a human, need to take much notice of in your day to day life because your brain has an "auto" white balance built in to it. So as you look around your environment your brain automatically adjusts the illuminated image to make it look more natural for you.

Our camera on the other hand deals with these different temperature lights by adjusting an internal setting called the White Balance. This setting can be adjusted automatically by the camera or manually by us - the user.
