Exposure compensation is a camera setting used in conjunction with automatic and semi-automatic shooting modes. It allows the photographer to dial in an amount that the camera should adjust its calculation either up or down, to increase or decrease exposure. An example of where this is helpful is when shooting a scene with a lot of white, such as a snowy landscape. The camera’s meter wants to make everything 18% gray, but if it exposes like that for a white, snowy scene, the resulting photograph will be underexposed. To counteract this, the photographer can use exposure compensation to dial in an increase in exposure while still shooting in an automatic or semi-automatic mode.
