to set fine adjustment value.
• The four directions are A (amber), B (blue), G (green) and M

The color displayed in the fine-tune screen for white balance represents the approximate color in the
color temperature direction. When a color is set in the fine-tune screen, it may not be reproduced
exactly in the image. For example, when the white balance is set to
Incandescent , the image will not
have a strong blue color even if fine adjustment is performed in the B (blue) direction.

Color Temperature
The perceived color of a light source varies with the viewer and other conditions. Color temperature
is an objective measure of the color of a light source, defined with reference to the temperature to
which an object would have to be heated to radiate light in the same wavelengths. While light
sources with a color temperature in the neighborhood of 5000–5500K appear white, light sources
with a lower color temperature, such as incandescent light bulbs, appear slightly yellow or red. Light
sources with a higher color temperature appear tinged with blue. The camera white balance options
are adapted to the following color temperatures.
