Auto white balance
This function enables the camera to automatically detect white in images and adjust the color
balance accordingly. Use this mode for general use.
Preset white balance
Seven different color temperatures are programmed on this camera covering a variety of
indoor and outdoor lighting including fluorescent lights and light bulbs. For example, use
preset WB when you want to reproduce more red in the picture of a sunset, or capture a
warmer artistic effect under artificial lighting.
Custom white balance
You can change the color temperature of one of the preset WB settings to your liking.

One-touch white balance
You can set the optimum white balance for the shooting conditions by pointing the camera at
a white object like a sheet of white paper. The white balance achieved with this setting is
saved as one of the preset WB settings.

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.
Setting the auto/preset/custom white balance
You can adjust the white balance by selecting the appropriate color temperature for the light
conditions.
