The Shooting Menu
White balance can be selected using the White balance option in the 
shooting menu (
0 176), which also can be used to fine-tune white 
balance (
0 92) or measure a value for preset white balance (0 94). 
The Auto option in the White balance menu 
offers a choice of Normal and Keep warm 
lighting colors
, which preserves the warm 
colors produced by incandescent lighting, 
while the 
Fluorescent option can be used to 
select the light source from the bulb types.

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, defined with reference 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 
neighborhood of 5000–5500 K appear white, light sources with a lower 
color temperature, such as incandescent light bulbs, appear slightly 
yellow or red. Light sources with a higher color temperature appear 
tinged with blue. The camera white balance options are adapted to the 
following color temperatures (all figures are approximate):
• I (sodium-vapor lamps): 2700 K
• J (incandescent)/
I (warm-white fluorescent): 
3000 K
• I (white fluorescent): 3700 K
• I (cool-white fluorescent): 
4200 K
• I (day white fluorescent): 5000 K
• H (direct sunlight): 5200 K
• N (flash): 5400 K
• G (cloudy): 6000 K
• I (daylight fluorescent): 6500 K
• I (high temp. mercury-vapor): 
7200 K
• M (shade): 8000 K
