This Grebe showed up as I was standing next to a bridge. I was in the shade and shooting Ducks in full sun,so was extremely under exposed. Just popped up and almost immediately went back under. I think he was surprised too. Processed in DPP 4 ,Photoshop and added some canvas on the right side.Levels adjustment.
