Chapter 4 Shooting — Adjusting the white and black balance
When you have no time to adjust the white balance
f Set the <WHITE BAL> switch to <PRST>.
The value can be changed to 3200 K, 5600 K, or the user-specified variable value by pushing the <AUTO W/B BAL> switch towards the <AWB>
side, and while the color temperature is displayed, pushing the <AUTO W/B BAL> switch towards the <AWB> side again. The variable value can be
changed with the jog dial button while the color temperature indication [V
**** K] at the bottom of the screen is highlighted. At this time, if the jog dial
button is turned while pressing, the setting value can be changed faster. Highlight disappears in several seconds if the setting is not changed.
When the white balance has not been automatically adjusted
f When the auto tracking white balance (ATW) function is operating, white balance cannot be adjusted.
f When the white balance has not been successfully adjusted, the viewfinder displays an error message.

Viewfinder display for white balance
For details, refer to “Screen status display” (page 166).
Setting the auto tracking white balance (ATW) function
The camera is equipped with the Auto Tracking White Balance (ATW) function that automatically tracks the white balance of images according to the
lighting conditions.
The auto tracking white balance function can be assigned to <B> of the <WHITE BAL> switch. Configure the settings in the main menu
→ [SW MODE]
→ [ATW].
Note that if the auto tracking white balance function is assigned to the USER button, the function follows the operation of the USER button.
For details, refer to “Assigning functions to USER buttons” (page 67).
Canceling the auto tracking white balance
Press the USER button to which auto tracking white balance function is assigned again or change the position of the <WHITE BAL> switch. Note that if
the auto tracking white balance function is set to the <WHITE BAL> switch, the function cannot be canceled with the USER button.
@ @
NOTE
t This function does not guarantee 100% accuracy for the white balance. Note that the tracking performance relative to changes in ambient lighting and
white balance performance has been given a certain degree of latitude.
Adjusting the black balance
Black balance must be adjusted in the following instances:
f When the camera is used for the first time
f When the camera has not been used for a long time
f When the ambient temperature has changed considerably
f When super gain is set with the USER button
f When changing the gain switch values
f When switching the items in the main menu → [SYSTEM MODE] → [REC FORMAT]
To shoot optimum video, we recommend adjusting the black balance immediately before shooting.
Before adjusting the black balance, prepare the conditions for adjusting the white balance.
1
Set the <WHITE BAL> switch to <A> or <B>.
2
Push the <AUTO W/B BAL> switch towards <ABB> and then release it.
The <AUTO W/B BAL> switch returns to the central position and the black balance is automatically adjusted.
