White Balance Fine-Tuning
The colors on the fine-tuning axes are relative, not absolute. Selecting
more of a color on a given axis does not necessarily result in that color
appearing in pictures. For example, moving the cursor to B (blue) when a
"warm" setting such as J [Incandescent] is selected will make pictures
slightly "colder" but will not actually make them blue.
D
"Mired"
Values in mired are calculated by multiplying the inverse of the color
temperature by 10
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 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.: Change in color temperature (in Kelvin): Value in mired
•
4000 K – 3000 K = 1000 K: 83 mired
•
7000 K – 6000 K = 1000 K: 24 mired
