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. The color temperatures for each of the white balance settings supported by the camera may be found in the Appendix ( 140). 13 - Auto BKT Set ( 90) This option to create a series of photographs "bracketing" the current white balance value.
