Underexposed Back-lit subjet

Underexposed Back-lit subjet

When a subject is lit from behind or is darker than it’s surroundings your camera can therefore be fooled into underexposing the most important part of the picture in an attempt to balance the exposure across the frame.
The easiest way to get the exposure well done with a backlit subject is to switch to either centre-weighted- or spot-metering.
Centre-weighted metering puts greater emphasis on exposing the centre of the frame correctly, while spotmetering only takes the brightness of the object under the spotmetering area into account when selecting the exposure settings.
Fortunately, your camera has a custom function that allows the spotmetering area to be linked to the active AF point, so even if your subject is off centre, it will be correctly exposed.
