White Balance

White balance is the level of light you have in your image.  It can either determine how light or dark one's image is.  This can  effect visibility of the film and an incorrect balance can result in the recording's color being offset.  Adjusting the white balance can also be used to strengthen or lessen shadows and reflections by increasing the levels at which the light is captured.  It is important because, depending on what the levels are or what you want them to be, the light  sources being used will either need to be adjusted or reconsidered.
