Choosing a Color Temperature

At a setting of K (Choose color temp.), color temperature can be selected by
pressing the WB button and rotating the sub-command dial until the desired value is
displayed in the control panel. Color temperature can also be selected in the
shooting menu (pg. 165).

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 5,000–
5,500 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.

Note that the desired results will not be obtained with flash or fluorescent lighting. Choose N
(Flash) or I (Fluorescent) for these sources. With other light sources, take a test shot to
determine if the selected value is appropriate.

The White Balance Menu
Color temperature can also be selected in the white balance menu. Note that the color
temperature with the WB button and the sub-command dial replaces the value selected in the
white balance menu.
