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 5000–5500K 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 camera white balance options
are adapted to the following color temperatures.
