Poynter.org has published an interesting article examining how photographer Iwan Baan took his striking post-Sandy picture of Manhattan, which is currently gracing the cover of New York Magazine. According to the article, Baan took his photograph of Manhattan - which is half blacked-out due to the destructive effects of Hurricane Sandy - from the open door of a helicopter hovering at 5000 feet above New York. He went up on the night of Wednesday 31st October, when limited air traffic made it possible to hover for longer - and higher - than would normally be allowed over a major city.

Dutch photographer Iwan Baan took this striking cover image from the door of a helicopter hovering 5000 feet above New York. This view shows very clearly the vast blacked-out areas of the city, caused by the destructive force of hurricane Sandy. 

According to Baan, heading upwards 'was the only way to show that New York was two cities [...] one was almost like a third world country where everything was becoming scarce. Everything was complicated. And then another was a completely vibrant, alive New York'. 

Baan took the picture using a Canon EOS-1D X, paired with the new EF 24-70mm F2.8 II USM lens. In an effort to get a sharp image from the vibrating helicopter he selected ISO 25,600 and shot wide open.
