It is from Moose Peterson, i fallow his blog and i have my D3s on the settings that are in this article. I had my D3s set this way on my summer trip to Yellowstone and had great results. I took 1300 pictures there and through out many but not because of focus. I always moved the red square on the eye if possible. Hope this helps.
I am not a pro and always learning. That is why i am a Nikonian.
