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–
5,500K 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:
•I (sodium-vapor lamps): 2,700K
•J (incandescent)/
I(warm-white fl.): 3,000K
•I (white fluorescent): 3,700K
•I (cool-white fl.): 4,200K
•I (day white fluorescent): 5,000K
•H (direct sunlight): 5,200K
•N (flash): 5,400K
•G (cloudy): 6,000K
•I (daylight fluorescent): 6,500K
•I (mercury-vapor lamps): 7,200K
•M (shade): 8,000K
