really, how does a camera do it?
does it change the shutter speed? or the aperture? does it depend on the camera mode eg A, M, P or S (or Tv)?
assume if the camera changes its shutter speed to effect the compensation and the camera is already set to the highest speed, does it mean putting -1 compensation have no effect?
can somebody pls enlighten me? try to find answer in many book, but there is no satisfying answer.
