Technical: Nikon D700, ISO 6400, +0.5 exp, Nikon 50mm f/1.8, f/2.8 @ 1/90s, auto white balance. RAW file processed in Lightroom 2 to crop and set Nikon Camera Landscape calibration.
The real story here is white balance and ISO performance. The auto white balance is perceptually spot on. I find that Nikon does a remarkable job with difficult white balance, but sometimes falls down on mundane conditions. The noise level in the blacks is remarkably low for the ISO. I recently made some pictures at ISO 3200 (see Tivoli Sign, Girlfriend Experience) and really don't see much difference in noise.
