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– 5,500 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.

AThe 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.
