1) Approach your subject and, looking in the
viewfinder, center your subject so that it
takes up about one-third of the viewing area.
2) While pressing the shutter button halfway,
press the AE lock switch.
3) Keeping the shutter button pressed halfway,
step back, compose the picture as you like,
and shoot. Your subject will be correctly
exposed.
You do not have to continue pressing the AE lock

you press the shutter button halfway.
