• 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
~~~
(incandescent)
is
selected for
white
balance will make photographs
slightly "colder"
but
will
not
actually make them blue.
R uMired"
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 Kthan 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 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
