    A little bit of underexposure to help keep the highlights
    under control.
    Three main situations for exposure compensation.
    1 is so the photographer can control mood - by either over
    or underexposing by an amount to get a lighter or darker
    image. Most photographers would run in full manual in that
    situation, but exposure compensation is a quicker way to set
    it, especially if you have changing light.

    2nd is to control highlights. Images with some very bright
    objects (clouds, lightbulbs etc) can be helped by
    underexposing a little. In some cases you may want to boost
    the shadows in post-processing, but that is possible to do.
    it is not possible to tone down highlights that have been blown.

    3rd reason is to adjust for scenes that will confuse the
    automatic metering. Scenes with a large amount of black or
    white will confuse the meter, and it will try to render the
    black or white as neutral gray - thus over or under
    exposing. Exposure compensation lets you adjust for these
    situations. Eg shooting in a snowfield, you will often need
    to dial in a little over-exposure, otherwise the white snow
    gets darkened to neutral gray and everything is underexposed.
