D White balance ne-tuning
The colors on the ne-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
6
. Any given change in color temperature produces a
greater dierence 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 lters.
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
