You can select the adjustment mode to suit

ATW (Auto Tracing White Balance)
This function adjusts the white balance
automatically to an appropriate level.
The white balance is automatically adjusted
when the color temperature of the light source
changes.
Press and hold the WHT BAL function button
(H) to display the direct menu (page 41)
and select ATW.
You can select the speed of adjustment
(five steps) using White Setting >ATW Speed
(page 76) in the Shooting menu.
[Tip]
You can freeze the current white balance setting by
assigning the ATW Hold function to an assignable
button (page 41), and pressing the assignable button
to temporarily pause ATW mode.
[Notes]
ˎ ˎ ATW cannot be used in Cine EI mode.
ˎ ˎ It may not be possible to adjust to the appropriate
color using ATW, depending on the lighting and
subject conditions.
Examples:
– When a single color dominates the subject, such as
sky, sea, ground, or flowers.
– When the color temperature is extremely high or
extremely low.
If the appropriate effect cannot be obtained because
the ATW auto tracking speed is slow or for other
reasons, run auto white balance.
