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.
A
Color Temperature Fine-Tuning
When Choose color temp. is selected, you can
view the color temperature while fine-tuning
white balance.
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
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
