The first thing that struck me about London was it's energy at night: Taxi lights, night buses, hurtling police cars... the smell of Jack Daniels and perfume mixed with sweat.
I took these pictures from the top of my night bus home after an evening in London's financial district. I almost didn't - I was cosy in my downstairs seat and tired after a long evening photographing glowing skyscrapers. Nevertheless I eventually coaxed myself upstairs to the top deck. God knows what my fellow passengers thought.
My shutter speed was five or six seconds. I had no idea what to expect. So I let serendipity, the bus and the rhythm of the dark streets take control...
