CREATIVE CONTROL
AE LOCK
When to use
Your X-7A's center-weighted av-
eraging
meter system is designed
so that light from all parts of the
viewfinder is measured, but influ-
ence
from a large central area is
greatest. Thus, when the main
subject fills most of the frame's
center, the meter reading should
give satisfactory exposure . However,
when there is a great brightness
difference
between the su bject and
background where the main subject
does not fill the center of the
frame, the AE lock should be used
(with
camera in auto mode).
Use
the AE lock in situations
where subjects appear dark against
strong backlighting, such as win-
dows,
or against a light background
of snow or sand; or where subjects
appear very light against a dark
background , as when standing in a
spotlight or shaft of sunlight.
How
to use
To obtain proper exposure in
high-contrast lighting
situations
where your subject is on the edge
of
the frame or occupies only a
small
portion in the center, use the
AE lock as follows :
1. Shift
the camera's position so
the sub j ect fills most of the frame.
For small subjects, you may need
to move closer (or zoom closer).
