4-1 Adjusting the Black Balance and White Balance

In order to maintain high picture quality when using
the camera, it is necessary to set the black balance and
white balance appropriately for the conditions.
Black balance adjustment
The black balance needs adjustment in situations like
the following:
• The first time the camera is used
• When the camera is used after a long period of disuse
• When the surrounding temperature changes greatly
• When the gain value is changed using the setup
menus
Normally, there is no need to adjust the black balance
every time the camera is turned on.
White balance adjustment
Always readjust the white balance when lighting
conditions change.
About the viewfinder screen
After the process of adjusting the black balance or
white balance begins, messages about the progress and
results of the adjustment will be displayed on the
viewfinder screen.
Note
Adjusted values set through automatic adjustment, and
other settings, are stored in the camera's memory and
preserved even when the camera power is turned off.
This memory will not be able to be maintained if the
backup battery on the IF-569 board runs down. The
battery life is approximately one year. If the battery
runs down, a warning message will be displayed on the
viewfinder screen each time the camera power is
turned on. Replace the battery when this message
appears.
Replace the battery within two or three days of when
the warning message is displayed. If not replaced
quickly, important data may be lost from the memory.
