With backlit scenes...
Compensate in range +0.3 EV to +2 EV
When taking backlit portraits against a bright sky or the sea, etc,
where the greater part of your picture is occupied by a bright
background, your subject will be underexposed and turn out dark
like a silhouette. In such cases, compensate exposure in the range
of +0,3 EV to +2 EV, to increase exposure.
When the background is dark...
Compensate in the range of -0.3 EV to -2 EV
If you are shooting a spotlighted subject on a stage where a dark
background dominates the scene, the main subject will be
overexposed and appear washed out. In such a case compensate
exposure in the range of -0.3 EV to -2 EV to reduce exposure.
