-EXPOSURE-continued---------------
Memory lock button
Another way of making exposure compensation with the F3AF
on
automatic
is
to
use
the exposure memory lock button.
When
there
is
a substantial difference
in
brightness between the main
subject and the background, such
as
a strongly backlit subject,
the camera's exposure meter
is
likely to be fooled, resulting
in
under- or overexposure (Fig. 1).
To
compensate for this,
center the main subject
in
the
viewfinder or move
in
close to
the subject, depress the memory lock button and hold it
in
; then
recompose and shoot (Fig.
2).
Note:
In
autofocus operation,
you
must also depress the focus lock
button when recomposing with
the
subject off-center
to
keep
it
in
sharp focus.
