Bright white background a silver umbrella as a side light near edge of frame on right. It shocked me. Didn't show up on a recent portrait session. But reared it's ugly head again on the latest chandelier shots, with lit bulbs (properly exposed) in the frame. Different size sensors may have a different affect. Camera baffle designs? I haven't tried to duplicate the anomaly in the 5D. I should do so.
