Looking Down on NYC
New York is so dense, that it can be difficult to see where the ground is when you're standing on the roof. I took this from the top of the rock, and this is one of only a couple spots where a street is visible.
This image is part Photomatix details enhancer, part Lightroom 32-bit HDR and part source file. Then some stylizing with Photoshop, Lightroom and Nik Color Efex.
