D Color Temperature
The perceived color
of
a light source varies
with
the viewer and other conditions. Color temperature
is
an
objective measure
of
the color
of
a light source, defined
with
reference
to
the temperature
to
which
an
object
would
have
to
be heated
to
radiate light
in
the same wavelengths. While light
sources
with
a color temperature
in
the
neighborhood
of
5,000- 5,500K appear white, light sources
with
a lower color temperature, such
as
incandescent light bulbs, appear slightly yellow or red. Light
sources
with
a higher color temperature appear tinged
with
blue.
Approximate color temperatures for each
white
balance setting are given
below
(when fine tuned
white
balance setting
is
±O.
Values may differ from color temperatures given by
photo
color meters.

Fine-Tuning White Balance
Unless Preset manual
is
selected, white balance
can
be "fine tuned"
to
compensate for
variations in the color
of
the light source or
to
introduce a deliberate color cast into
an
image.
1 Select a white balance option except Preset
manual.
Select White balance
in
the shooting menu, then
highlight
a
white
balance
option
and
press
the multi
s:
selector right. If Fluorescent
is
selected,

balance can be fine
tuned
on
the
amber (A)-blue

axis
and the green (G)-magenta

axis.
The horizontal
(amberblue)

corresponds
to
color temperature,
with
each increment equivalent
to
about 5 mired. The vertical
