Nikon's 3D Matrix Metering II does a really great job of determining
exposure. Here's it managed to maintain detail in both the bright parts of
the bark of this tree while also holding detail in the deep shadows on the
bottom left. Shot details: Nikon D700; ISO 400; 1/125 sec.; f/8; AF-S Nikkor
24-70mm f/2.8G ED zoomed to 60mm
