AThe Shooting Menu

White balance can be selected using the White balance option in the shooting menu (0 222), which also can be used to fine-tune white balance (0 127) or measure a value for preset white balance (0 129).

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 5000–5500 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

• H(direct sunlight): 5200 K

• J(incandescent)/

• N(flash): 5400 K

I(warm-white fluorescent):

• G(cloudy): 6000 K

3000 K

• I(daylight fluorescent): 6500 K

• I(white fluorescent): 3700 K

• I(high temp. mercury-vapor):

• I(cool-white fluorescent):

7200 K
4200 K

• M(shade): 8000 K

•I(day white fluorescent): 5000 K
