b3: Center-Weighted Area
When calculating exposure, center-weighted metering
assigns the greatest
weight
to
a circle in the center
of
the
frame. The diameter
(</»
of
this circle can be set
to
6,8,
or
10 mm. This
option
is
available in
P,
S,

Fine-Tuning Exposure
Exposure
can
be fine-tuned separately for each Custom Settings bank and
is
not
affected by
two-button
resets. Note
that
as
the exposure compensation
(~)
icon
is
not
displayed, the only
way
to
determine
how
much exposure
has
been altered
is
to
view the
amount
in the fine-
tuning
menu. Exposure compensation (pg.
90)
is
preferred in most situations.
