[QUOTE="nickt, post: 605160, member: 4923"] It depends what mode you are in. Exposure compensation pushes the meter reading up or down to influence the exposure. The camera will use whatever parameter it has control of at the time to satisfy the meter. So if auto iso is on, it will change iso to make the meter happy and that will directly affect noise. Other than that, noise is noise and you will get whatever noise your camera would normally give you for a particular scene at specific settings.
