Jason Hawkes is one of the world's most prolific and sought-after aerial photographers. He has been hovering over cities with a camera since 1991 - initially in microlight aircraft and then hanging out of helicopters.
Jason was the official photographer on the BBC's huge Britain From Above project. He has published more than 40 books, including New York at Night and London at Night. His first book, London from the Air, came out when he was just 23 and has gone on to sell more than 160,000 copies.
He says he loves shooting just after dusk, when the city lights come on and there is a tiny bit of colour left in the sky. New advances in digital camera technology allow him to capture the city at night.
Jason says: "Each time I fly over London I notice the landscape constantly changing, new developments seem to appear overnight."
In this gallery, IBTimes UK presents some of his recent photographs of London from the air. To see more, visit his website at www.jasonhawkes.com. Follow Jason on Twitter at @jasonhawkesphot for the latest info and behind-the-scenes pictures.
