[] 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 Kappear 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:
• _ (sodium-vapor lamps): 2,700K
• ;_ (incandescent)/
(warm-white fluorescent): 3,000K
