White Balance Fine-Tuning

If white balance has been fine-tuned, an
asterisk (“

E

”) will be displayed in the

information display. Note that 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.

“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
