White Balance

"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,
at a color temperature of 6000 K, a
change of 1000 K produces almost no
change in color, while a change of the
same amount at 3000 K would produce
a large difference in color. Mired, calcu-
lated by multiplying the inverse of the
color temperature by 10
of color temperature that takes such
variation into account, and as such
is the unit used in color-temperature
compensation filters.

The values for red and blue gain
chosen in the White Balance palette are

the photograph was taken.
Choosing a Value for Gain
Very large and small values for gain can
result in a drop in image quality.
