Nikon D800E bracketing
So I tried to use bracketing yesterday and it did not work as i expected on my D800E. I had the bracketing set at 7F @ 1 stop increments. In the menu (e5) its set to AE & Flash. Menu e^ is set to Flash/Speed and e7 is set to Under >MTR>over. I was expecting to get a perfect exposure, 3 under and 3 over in 1 stop increments. What i am getting is a perfect exposure, and 6 over in 1 stop increments. What am I doing wrong? Please help.
