White balance can also be adjusted using the White balance 
option in the shooting menu (

0 224), which also can be used to 

fine-tune white balance (

0 91) or measure a value for preset white 

balance (

0 95). 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 

I Fluorescent option can be used to select the light 

source from the bulb types.

Auto white balance may not produce the desired results with large studio flash units. Use 
preset white balance or set white balance to Flash and use fine tuning to adjust white 
balance.

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

When WB bracketing is selected for Custom Setting e6 (Auto bracketing set, 

camera will create several images each time the shutter is released. White balance will be 
varied with each image, “bracketing” the value currently selected for white balance (
