Fine-Tuning White Balance
At settings other than (Choose color temp.) and PRE (preset), white
bal ance can be “fi ne tuned” to compensate for vari a tions in the color of
the light source or to in tro duce a deliberate “warm” or “cold” cast into
an image. Higher settings can be used to lend im ag es a blu ish tinge or to
com pen sate for light sources with a yellow or red cast, while low er ing white
bal ance can make pho to graphs ap pear slight ly more yellow or red or com-
pen sate for light sources with a blue cast. Adjustments can be made in the
range +3 to –3 in in cre ments of one. Except in Fluorescent mode, each
in cre ment is equiv a lent to about 10 mired.

“Mired”
Any given change in color temperature produces a greater difference in color at low
color tem per a tures than it would at higher color temperatures. For example, a change
of 100 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 fi lters. E.g.:
• 4000 K – 3000 K (a difference of 1000 K) = 83 mired
• 7000 K – 6000 K (a difference of 1000 K) = 24 mired
