48 Adjustments and Settings for Recording : Adjusting the White balance and Black Balance
OUTPUT: CAM
Each value in memory is retained even if the camera-
recorder is turned off.
Notes
Ensure that the lens connector is connected and
the lens iris is CLOSE.
During a black balance adjustment, light is
automatically cut off.
During a black balance adjustment, the gain
switchover circuit is automatically switched.
The viewfinder screen may flicker and/or display
noise; this is not a failure.
If you find the black shading annoying after
performing an auto black balance adjustment,
adjust the black shading. To do so, go to the menu
option DETECTION, move the cursor ( > ), then
press the JOG dial button. The menu option
DETECTION can be found in the <BLACK
SHADING> screen, which is accessible from the
MAINTENANCE page.
By turning on the SHD.ABB SW CTL in <SW
MODE> (page 178) and then continuously pressing
the ABB switch for 8 seconds or longer, black
shading can be automatically adjusted after the
Auto-Black-Balance operation. While the black
shading is being adjusted, ensure that the lens iris is
closed completely until the "B-SHD OK" message is
displayed in the viewfinder.
However, when the remote control unit (AJ-RC10G:
optional accessory) is connected, automatic black
shading cannot be executed even if the ABB switch is
held down.
To cancel the automatic black balance adjustment
in process (the viewfinder displays "ABB ACTIVE"),
flip the AUTO W/B BAL switch down to [ABB] again.
If automatic adjustment is cancelled, the value in
effect before automatic adjustment will be used.
