Called whenever the camera parameters change. In automatic exposure modes (Program, Shutter Priority and Aperture Priority) the camera may be automatically changing aperture, shutter speed and ISO (depending on the mode and camera) when lighting conditions change. In Manual mode, the exposure compensation is automatically updated to let the user know how much compensation the exposure needs to get to an exposure the camera calculates as correct.
