AThe Shooting Menu
White balance can also be adjusted using the White balance
option in the shooting menu (0214), which also can be used to
fine-tune white balance (0117) or measure a value for preset
white balance (0121).
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 IFluorescent option can be used to select the
light source from the bulb types.
AStudio Flash Lighting
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.
AColor 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 5,000–
5,500K 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:
•I (sodium-vapor lamps): 2,700K
•J (incandescent)/
I(warm-white fluorescent): 3,000K
•I (white fluorescent): 3,700K
•I (cool-white fluorescent): 4,200K
•I (day white fluorescent): 5,000K
•H (direct sunlight): 5,200K
•N (flash): 5,400K
•G (cloudy): 6,000K
•I (daylight fluorescent): 6,500K
•I (high temp. mercury-vapor): 7,200K
•M (shade): 8,000K
