When you dial in an exposure compensation, say EV+1, EV-2, or whatever, where does that change in exposure come from? I have not been able to see any change in ISO, shutter speed or f/stop to account for these compensations that are added to or subtracted from the exposures to change them. So were does the change in exposure come from??

Can anybody answer this one? Feel free to use one of your lifelines if necessary.
