A
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
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
