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, defi ned 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. The color temperatures for each of the white bal-
ance settings supported by the camera may be found in the Appendix (
140).
