3.8. White Balance Adjustment
In digital video cameras, photographing white as pure white is described as "having the
appropriate white balance". In the system's color models as well, in order to record 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 in 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.
3.8.1. Using Preset White Balance
This system has 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)
3.8.2. Using User White Balance
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”.
