I use Aperture or Shutter priority and use exposure compensation for the tricky lighting shots. I suppose that using manual would accomplish the same thing, just using different controls... I have not used the auto bracketing feature, which might be helpful in certain instances. Using the "spot" meter :roll: on the 20D is fairly helpful when lighting issues pop up, but I do wish there was a REAL spot meter!! Evaluative metering never gets backlighting right no matter what they claim.
