shooting environment. You can select the most appropriate
white balance setting for a given shooting environment by setting
up a custom white balance.
1. Select Custom ( ) in the White
Balance Menu, and then place a
sheet of white paper in front of the
camera so that the LCD screen
shows only white.
2. OK button : Selects the previous
custom white balance.
Shutter button : Saves the new custom white
balance.

What is color temperature?
The Color Temperature scale is a conventional measure of color
expressed in degrees Kelvin (K). The scale runs from reds and yellows
at the low end (below about 2700 K) to blues at the high (above about
5000 K). Every light source, for example, an incandescent bulb, radiates
light that is mainly one color (see the scale above). This one color can
distort the natural colors of a scene, giving everything in the scene a
distinctive color cast. Your camera lets you change the color temperature
setting of the white balance to adjust for the light source so that when
you take pictures, the colors in the picture look natural.
The Color Temperature scale correlates the temperature of what is called
an ideal black body radiator to the color it radiates at that temperature.
For example, a black body radiator glows red when heated to about
2000 degrees Kelvin and glows blue when heated to about 10,000
degrees Kelvin. The color of light from another source, for example, a
fluorescent light, can be correlated to the color radiated by the black
body at a certain temperature, and then expressed in degrees Kelvin.
