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–
5500 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 camera white balance options are adapted to the following
color temperatures (all figures are approximate):
•
I (sodium-vapor lamps): 2700 K
•
J (incandescent)/
I (warm-white fluorescent): 3000 K
•
I (white fluorescent): 3700 K
•
I (cool-white fluorescent): 4200 K
•
I (day white fluorescent): 5000 K
•
H (direct sunlight): 5200 K
•
N (flash): 5400 K
•
G (cloudy): 6000 K
•
I (daylight fluorescent): 6500 K
•
I (high temp. mercury-vapor): 7200 K
•
M (shade): 8000 K
