# 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.

1. <AUTO W/B BAL> switch

   Use to execute the automatic black balance.

2. <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.

#### Message displayed in the viewfinder screen

During adjustment |  |
Adjustment completed |  | The adjusted value is automatically stored in memory.

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.

## Black balance memory

Values stored to memory are saved even if the camera is turned off.
