This is probably a real dumb question but here goes.
If I am shooting in shutter speed mode and the lens is already open as wide as possible, say f 5.6 on my 100~400 L lens, and I have the ISO set to 200, and the shutter speed set to 1/800 sec. Does exposure compensation do anything?
If so, what is the camera changing to add more light to the shot? This has been on my mind for a while now and just decided to ask a dumb question.
Thanks for your time and patience.
