Hi. I've had point and shots for years, and rarely used exposure compensation, now i am happily using mu43 cameras, I still don't use this much. I have played with it but can't seem to grasp it's use? This may be obvious but... How does it work,? I assume it's different from changing the aperture. And if so, is it some digital process that I can do afterwards? If not then, how might in use this feature? Am I missing something? Thanks in advance!
