Shooting techniques
The camera automatically adjusts the
exposure according to the subject. If you
change the composition of your shot, the
exposure may be changed, such as by
changes in the brightness of the background.
In such cases, use the AE lock function. You
can shoot freely, regardless of the brightness
of the subject.
To determine the exposure, measure the
exposure of the desired portion of the
subject using either center-weighted
metering or the spot metering function.
Press AE LOCK to lock the exposure, and
then recompose the picture and shoot.
