Today, if I had to do it again, I would shoot this scene with the Brenizer Method (google it) with my D3 and a different lens and stitch a panorama together with Photoshop.
However, this 2007 photo was shot with a 30 second exposure at 12mm at f/22, with a Nikon D200 on a tripod. I remember it was quite nice outside and not too cold.
