Big Picture: NYC and Las Vegas from above, at night

Photographer Jason Hawkes, a frequent contributor to the Big Picture blog, returns today, sharing with us some of his latest images of American cities seen from above at night - New York City and Las Vegas, both cities that undergo significant transformations after the sun goes down. From Hawkes: "The images of New York were shot on Nikons latest camera, the D3S, using three gyro stabilizing mounts and flown using twin star helicopters. (Eurocopter AS355). We flew from heights of just over 500 ft up to 2,500-ft with no doors on, it was very very cold. The images of Las Vegas were shot for a separate project, using a range of helicopters from a Robinson 44 to Eurocopter AS355". Be sure to see Hawkes' earlier entries here (1, 2, 3), and check out his newly-released book "London at Night". A book of his New York at night photos is due for publication in the Autumn.
