AWB stands for auto white balance. It is a camera setting that automatically adjusts the colors of an image to match the color temperature of the light.
The aim is to make white objects look white and colors look natural, as the human eye sees them, whether the light is warm, like a tungsten lamp, or cool, like shade. AWB works well in most situations, but it can be fooled by scenes with one strong color or mixed light. See also white balance.
