What mode is your camera most often in? Why?

I'm not quite sure what Exposure Compensation is. On my 7D when using P it picks a couple that will give what it thinks will be a correctly exposed image at that ISO. by rolling one wheel both A & S settings will change still giving a correct exposure (ie shutter gets faster and Aperture larger, or the oposite)...but one can also rotate the back wheel which will allow an over or under exposing but altering one of the two. The centre mark in the viewfinder goes to the right or left of the centre mark allowing you to see whether you are over or under exposing. So hence you have complete control over shutter, aperture and any over or under exposing that you choose. I think this meats M where you have to set both Shutter and Aperture and involves more thought!
