The higher the color temperature, the richer the light
in bluish tones and the poorer in reddish; the lower
the color temperature, the richer the light in reddish
tones and the poorer in bluish. The spectral balance
of different white light sources is rated numerically by
color temperature – concept of physics expressed
using the Kelvin (K) temperature scale. The color of
sunlight and other natural light sources and the color
of a light bulb and other artificial light sources can be
expressed in terms of color temperature.
It follows, then, that the color temperatures of
fluorescent lights make them unsuitable as artificial
light sources. There are gaps in the hues from the
color temperatures of fluorescent light. If these differences in hue are small, they can be
calculated with color temperature and this is called correlated color temperature.
The 4000 K, 4500 K and 6600 K preset settings in this camera are correlated color
temperatures, and should not be considered strictly as color temperatures. Use these settings
for shooting conditions under fluorescent lights.
