However, if you are in Manual mode, then you cannot dial in EV compensation. Take the above scene again. ISO=100, you choose aperture f/4.0, shutter speed 1/500th sec. Since that was exposure level chosen at either AV or TV mode with 0 EV compensation, therefore, the meter indicator will be in blinking at the middle of the scale. You want to overexpose the scene by +2/3 stops, then you need to either go for f/3.2 (you are on manual mode) or 1/320th sec (or 1/3rd stop larger aperture and 1/3 stop slower shutter speed or any such combination)
Bottom line is in AV/TV mode you can dial in the Exposure Compensation and camera changes the shutter speed/aperture; in Manual mode to get a higher exposure you need to choose the shutter speed or aperture or both yourself.
Yes, I shoot M and was thinking that maybe Exposure Compensation would shift what the light meter displays.
thanks for the info
