AThe Shooting Menu
White balance can be selected using the White balance option in
the shooting menu (0150), which also can be used to fine-tune
white balance (078) or measure a value for preset white balance
(079).
The IFluorescent option in the White balance menu can be used
to select the light source from the bulb types shown at right.
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 5000–
5500K 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): 2700K
•J (incandescent)/
I(warm-white fluorescent): 3000K
•I (white fluorescent): 3700K
•I (cool-white fluorescent): 4200K
•I (day white fluorescent): 5000K
•H (direct sunlight): 5200K
•N (flash): 5400K
•G (cloudy): 6000K
•I (daylight fluorescent): 6500K
•I (high temp. mercury-vapor): 7200K
•M (shade): 8000K
