3.10. White Balance Adjustment (Color Types Only)
On digital video cameras, photographing white as pure white is described as "having the appropriate
white balance." On the system's color types as well, in order to take images with the correct color
representation, the white balance must be adjusted for the color temperature of the light source used.
The intensity of each color, R, G, and B, can be adjusted on this system. By adjusting the balance of
those three colors to match the light source used, the appropriate white balance can be achieved.
Two methods are available for adjusting the white balance, preset and user-editable white balance.
These methods are explained in this section.
3.10.1. Using Preset White Balance (Color Types Only)
With the system, there are two types of white balance presets (5100K, 3100K) for use with common
light sources. The suggested color temperature for these presets is listed below.
 5100K (Daylight, Outdoors)
 3100K (Halogen Light Source)
3.10.2. Using User White Balance (Color Types Only)
User white balance can be set in order to achieve the most appropriate white balance for the light
source used with the system and the conditions during recording.
The values set here are stored in the camera body's internal memory as the user preset, and they
can be loaded by selecting USER.
There are also two methods for setting user white balance, AUTO USER and EDIT USER.
