Most of the good locations can be found by just walking around (in sometimes stranges areas). I t took me about an hour to find this spot, with an almost perfect view of the south-west side of Times Square, and the brand new New York Times building. It’s not really a hyper-wide panorama since it’s only 80 degrees view, but I think it still fits into the family. I posted a zoomify version with the full gigapixel resolution on portfolio site at luminous-newyork.com
About 1 gigapixel.
