Adjusting White Balance Settings
White balance is normally compensated for by the automatic white balance gain control. In
some lighting conditions, you may need to manually adjust the red and blue settings for
optimal viewing.
When Automatic White Balance is enabled, the red and blue setting values are based on
feedback from the camera. When Automatic White Balance is disabled, the camera uses the
red and blue setting values to control the white balance. When Automatic White Balance is
first switched from On to Off , the red and blue values displayed are based on the current
feedback from the camera. The red and blue values range from 0 to 511. Changes occur in
increments of 5.
The following chart illustrates the red and blue settings relationship to white balance.
As the value for the red setting increases, the image appears more red. As the value decreases,
the image appears less red.
As the value for the blue setting increases, the image appears more blue. As the value
decreases, the image appears less blue.
As the values for both the red and blue settings are increased, the image appears more
magenta (purple). As the values for both the red and blue settings are decreased, the image
appears more green.
