setting of White Balance is appropriate for typical lighting conditions.    See the topic 
"Adjusting Color Balance" for general guidance on using Neutral and Auto levels to 
handle these cases if White Balance is not right. 
  None  
The black and white points aren't used at all, and the image is only corrected 
for the CCD's color response (if the Media option is set to Image) or by the 
film's color response.    This image is gamma corrected. 
  Manual  
Both the black and white points are used to stretch the image's intensity range.   
However, the relative ratios of red, green, and blue are specified manually. 
  Neutral  
Both the black and white points are used to stretch the image's intensity range.   
However, the relative ratios of red, green, and blue are kept constant. 
  Tungsten  
Both the black and white points are adjusted to compensate for an image lit by 
tungsten light (i.e. a normal incandescent light bulb).    This removes the reddish 
cast from indoor pictures taken without a flash. 
  Fluorescent  
Both the black and white points are adjusted to compensate for an image lit by 
fluorescent light.    This removes the greenish cast from indoor pictures lit by 
fluorescent lights or lit by flash. 
  Night  
Both the black and white points are adjusted to compensate for an image taken 
at night.    The white balance is determined from the darkest 10% of the image, 
which often produces the best results when images have bright fluorescent or 
incandescent lights that are greenish or yellowish.
