Color temperature
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 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.
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.
