White balance — Adjusting the color tone

Exposure, image and color
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.
TIPS
White balance with a flash:
J Auto WB is recommended when taking pictures with the flash.
If you intend to use preset WB, select the color temperature 6000K. When
shooting with the flash, be sure to play back your pictures and check the
color on the screen. Various conditions affect color temperature and how
color is reproduced on the screen.
Notes
• The color temperatures for each light source indicated in the above scale are
approximate. They are not an accurate indication of color. For example, the actual
sunlight is not exactly 5300K, nor fluorescent lights 4000K.
