Increasing exposure to counter backlight on a subject. Because most metering systems tend to underexpose a backlit subject, it's generally a good idea to increase exposure by about 1.5EV.
Backlight compensation is usually done automatically, but some camcorders offer it as a manual option. What it does is compensate for too much light behind the subject, which would normally create just a silhouette. So, in effect, it reduces the backlight, while concentrating the light on the subject.

Ensures that your subject will be properly exposed, even under difficult lighting conditions. When the subject is in front of a bright background, like the sun or bright lights, the gain or aperture setting is increased to allow more light, which brightens the picture and reveals more detail. This is typically done automatically, but some camcorders let you adjust the backlight setting manually.
