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 will make photographs slightly “colder”
but will not actually make them blue.
A 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.
A “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
6
, is a measure of
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
