Fine-Tuning White Balance
At settings other than 
  (Choose color temp.) and PRE  (preset), white 
bal ance can be “fi ne tuned” to compensate for vari a tions in the color of 
the light source or to in tro duce a deliberate “warm” or “cold” cast into 
an image.  Higher settings can be used to lend im ag es a blu ish tinge or to 
com pen sate for light sources with a yellow or red cast, while low er ing white 
bal ance can make pho to graphs ap pear slight ly more yellow or red or com-
 pen sate for light sources with a blue cast.  Adjustments can be made in the 
range +3 to –3 in in cre ments of one.  Except in Fluorescent  mode, each 
in cre ment is equiv a lent to about 10 mired.
White balance is fi ne tuned using the White bal. option in the shooting 
menu or by pressing the WB button and rotating the sub-command dial.

 Color Temperature
The perceived color of a light source varies with the viewer and other conditions.  Color 
temperature is an objective measure of the color of a light source, defi ned with ref-
 er ence to the temperature to which an object would have to be heated to radiate light 
in the same wavelengths.  While light sources with a color temperature in the neigh-
 bor hood of 5,000–5,500 K appear white, light sources with a lower color tem per a ture, 
such as incandescent light bulbs, appear slightly yellow or red.  Light sourc es with a 
higher color temperature appear tinged with blue.
