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 will make photographs slightly "colder"
but will not actually make them blue.

Touch Fine-Tuning
To fine-tune an option in the white balance menu using the touch
screen, tap the option once to highlight it and then tap the 2 Adjust
button to view the fine-tuning display. To choose a value, tap the
coordinate display or the u, v, x, or y icons. Tap 0 OK to return to the
shooting menu once white balance has been adjusted to your
satisfaction.

"Mired"
Any given change in color temperature produces a greater difference
in color at low color temperatures than it would at higher color
temperatures. For example, a change of 1000 K produces a much
greater change in color at 3000 K than at 6000 K. Mired, calculated by
multiplying the inverse of the color temperature by 10
color temperature that takes such variation into account, and as such is
the unit used in color-temperature compensation filters. E.g.:
• 4000 K–3000 K (a difference of 1000 K)=83 mired
• 7000 K–6000 K (a difference of 1000 K)=24 mired
