From the roof of a friend of a friend about 30 minutes before sunset. I think. It was too cloudy to know when the sun actually set. Looking north from 56th Street. From here, you can see the George Washington Bridge across the Hudson River, about 6 miles up. I went with a smaller aperture to get a longer exposure, and I think image quality suffered a little bit as a result.
