I was walking up towards London Bridge station after work this week, when I spotted this:

I stopped to speak to the photographer, who was looking a bit bored. He was in the process of taking a time lapse series of the sun going down on the Shard for a trade advert. He's mistimed it a bit, as he had already been there for an hour and a half, he said, and had about another hour and a half till he was done. He said he was doing one photo every fifteen seconds, which is a lot of images. I hope he had enough storage.
No, I don't know what his kit was. One black plastic SLR looks much like another to me.
