Fine-Tuning White Balance
White balance can be “fine tuned” to compensate for variations in the color of the
light source or to introduce a deliberate color cast into an image. White balance is
fine tuned using the White balance option in the shooting menu or by pressing the
WB
button and rotating the sub-command dial.

Fine tune white balance.
Use the multi selector to fine-tune white
balance. White balance can be fine tuned on
the amber (A)–blue (B) axis and the green (G)–
magenta (M) axis. The horizontal (amber-blue)
axis corresponds to color temperature, with
each increment equivalent to about 5 mired.
The vertical (green-magenta) axis has the
similar effects to the corresponding color compensation (CC) filters.
A White Balance Fine Tuning
The colors on the fine-tuning axes are relative, not absolute. For example, moving the cursor
to B (blue) when a “warm” setting such as
J (incandescent) is selected for white balance will
make photographs slightly “colder” but will not actually make them blue.
