[QUOTE="daredevil123, post: 113772, member: 11958"] Wayne, I think you misunderstood. What Desmond is saying is that the metering is based on the brightest AF point. Not the selected AF point. so moving AF points does nothing. I did this test before many times because I wanted to be sure. My conclusion is that on TTL-BL, the introduction of a bright object in the frame over any AF point matters. It is not just a simple middle of the frame metering. I have also shot with perfect flash exposure where the people in the frame is not in the center with a dark background. By your reasoning, those kind of pictures should result in the subject being over exposed, but they did not. Perhaps you can explain why the flash power for the following two pictures differ? Pictures shot moments from each other a couple of minutes ago. D4 + SB-600 (on TTL-BL), FV0, EV0, 1/160s, F5.6, ISO200, Matrix. No settings changed between the shots. camera on tripod. AF point on center point. Pictures are out of camera JPG, unadjusted, but resized to 1024 on the long end.
