If you want to brighten that dark shot, or add light, this is the tool to do it with.  Just be careful, as the more this effect is used, your video quallity will often degrade.  use this along with Keyframing to brighten a long shot that is dark at the begining, but bright at the end.  Generally you will want to want to change the brightness and contrast about the same amount (eg darkness 28 contrast 26) so that your origanal colors will be kept intact.
