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 4000K, 4500K and 6600K 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.
