AWhite 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.

AColor 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 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
