Adjusting the black balance

Black balance must be adjusted in the following instances:

When the camera is used for the first time
When the camera has not been used for a long time
When the ambient temperature has changed considerably
When super gain is set using the <USER> buttons (<USER MAIN>/<USER1>/<USER2>)
When [DS.GAIN] is assigned to [USER MAIN], [USER1], [USER2], and [USER5] in the main menu → [CAMERA] → [USER SW]
When the digital super gain assignment is changed in the main menu → [CAMERA] → [USER SW GAIN] → [DS.GAIN]

To shoot optimum video, we recommend adjusting the black balance immediately before shooting.

<AUTO W/B BAL> switch
Use to execute the automatic black balance.
<OUTPUT> switch
Set this switch to <CAM>.

Set the <AUTO W/B BAL> switch towards <ABB> and then release it.

The switch returns to the central position with the black balance automatically adjusted.

Adjustment is completed in several seconds.

NOTE

Make sure that the lens connector is connected and that the lens aperture is in the close mode.
During black balance adjustment, the aperture is set to automatically shut out light.
During recording, black balance cannot be adjusted.
During the automatic black balance execution, recording to the P2 card is not performed by pressing the <REC> button.
The gain switching circuit is automatically switched during black balance adjustment. Flicker or noise sometimes appears on the viewfinder screen. This is not a malfunction.
Even after automatic black balance has ended, if black shading is a cause for concern, select [DETECTION(DIG)] in the main menu → [MAINTENANCE] → [BLACK SHADING], and execute black shading adjustment. Alternatively, set the main menu → [CAMERA] → [SW MODE] → [SHD,ABB SW CTL] to [ON] and hold down the <AUTO W/B BAL> switch for two seconds or more to adjust black shading. [B-SHD READY] will be displayed in the viewfinder, and black shading can be automatically adjusted after the automatic black balance operation. While black shading is being adjusted, [B-SHD ACTIVE] will be displayed in the viewfinder. After this, be sure to close down the lens aperture until [B-SHD OK] is displayed in the viewfinder. However, when the extension control unit AG-EC4G (optional) or remote operation panel AK-HRP200G (optional) is connected, black shading cannot be automatically adjusted even by holding down the <ABB> switch.
When black balance is being automatically adjusted (when [ABB ACTIVE] is displayed in the viewfinder), adjustment is canceled by pushing the <AUTO W/B BAL> switch towards <ABB> again. The adjustment values at this time return to the values before automatic adjustment was performed.
