There are also the usual array of improvements and additions to shooting controls, including an expansion of Active D-Lighting parameters (you can now go extra high), nine slots for custom Picture Control settings, which can be uploaded to Nikon's Capture NX 2 raw-processing software, as well as advanced scene modes that incorporate Picture Controls and Active D-Lighting, and that can automatically program shift to slower shutter speeds when the camera knows a VR lens is attached.

It's not just the size that's impressive, but the saturation, clarity and sheer definition.
