A White Balance Fine-Tuning
If white balance has been fine-tuned, an asterisk (“E”) will be displayed
next to the white balance setting.
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.

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

When WB bracketing is selected for Custom Setting e6 (Auto
bracketing set, 0 284), the camera will create several images each
time the shutter is released.
White balance will be varied with each
image, “bracketing” the value currently selected for white balance
(0 202).
