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.
