This was shot from Jersey City, which sits just across from lower Manhattan. To find this vantage point, head to the New Jersey PATH terminal (the one named Exchange Place -- some Diggers pointed out that there are several), then walk north until you come to a pier in front of the Hyatt. This is the view from that pier.
This is actually shrunk down quite a bit; the original is almost 25,000 pixels wide.
**edit** Q&A time! I've had a bunch of questions about the technical details of this shot, so, here goes!
This is a panoramic stitch of 8 photographs. They were taken with a Canon EOS 20D using a Sigma 70-200 2.8 telephoto lens set to 70mm. The lens was tripoded, and each shot was shot using a cable release. I shot it RAW and processed the using Adobe Photoshop CS2. I stiched them using Adobe's stitching utility, however I set everything to manual and did it in layers, as the Photoshop stitcher had a hard time figuring out what to do with the color changes in the sky over time. I processed each layer individually so that the colors would match up, and then overlapped them and then painted layer opacity screens over the edges to make it as seamless as possible. (There are actually spots where the edges don't line up so hot, but I tried to keep those spots in the sky/water so it's harder to tell. :)) I actually have two more versions of this, one at dawn and one at night. :)
