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 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 4000 K, 4500 K and 6600 K 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.
