White balance — Adjusting the color tone
Color reproduction differs depending on the light conditions. For instance,
when daylight or tungsten lighting is reflected on white paper, the shade of
white produced will be slightly different for each.
With a digital camera, white color can be adjusted to reproduce more natural
white with a digital processor. This mechanism is called white balance. There
are 4 options for setting the WB with this camera.
Auto white balance
This function enables the camera to automatically detect white in images and
adjust the color balance accordingly.
Use this mode for any scene. If there is no near white color in the picture, the
white balance of the image may not be correct. In such a case, use preset WB
or one-touch WB to achieve the correct white balance.
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. You can enjoy creating different color tones by trying the different
preset WB settings.
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.
