3 Save changes and exit.
Press J to save settings and return to
the photo shooting menu. If white
balance has been fine-tuned, an
asterisk (“U”) will appear next to the
white balance icon in the shooting
display.
D 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.
D “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
