 White Balance Correction
With just one shot, three images having a different color balance can be 
recorded simultaneously. Based on the color temperature of the current white 
balance setting, the image will be bracketed with a blue/amber bias or 
magenta/green bias. This is called white balance bracketing (WB-BKT). White 
balance bracketing is possible up to ±3 levels in single-level increments.
Set the white balance bracketing amount.
In step 2 for white balance correction, when 
you turn the <5> dial, the “ ” mark on the 
screen will change to “     ” (3 points).
Turning the dial to the right sets the B/
A bracketing, and turning it to the left 
sets the M/G bracketing.
On the right side of the screen, “BKT” 
indicates the bracketing direction and 
the bracketing amount.
Pressing the <B> button will cancel 
all the [WB SHIFT/BKT] settings.
Press <0> to exit the setting and 
return to the menu.
Bracketing Sequence
The images will be bracketed in the following sequence: 1. Standard 
white balance, 2. Blue (B) bias, and 3. Amber (A) bias, or 1. Standard 
white balance, 2. Magenta (M) bias, 3. Green (G) bias.
White Balance Auto Bracketing
B/A bias ±3 levels
During WB bracketing, the maximum burst for continuous shooting will be 
lower and the number of possible shots will also decrease to one-third the 
normal number. Also, the white balance icon will blink on the rear LCD panel.
You can also set white balance correction and AEB together with white 
balance bracketing. If you set AEB in combination with white balance 
bracketing, a total of nine images will be recorded for a single shot.
Since three images are recorded for one shot, the card will take longer to 
record the shot.
BKT” stands for Bracketing.
