Autoexposure Lock - Nikon Digital Camera Reference Manual

Autoexposure Lock

Exposure lock is used to recompose photographs after metering
exposure. It is most effective when used with center-weighted or
spot metering (0 117) to frame off-center subjects that are
much brighter or darker than their surroundings or to optimize
exposure for an object other than your main subject.
