Atop the 95-storey skyscraper known as The Shard, Will Pearson captured an amazing photo of all of London at dusk. At the link, you can manipulate the image by zooming and panning. Pearson writes:
Technically this was a very difficult shoot, I was on the crane at the top of the Shard, and I had to wave at Andy the crane driver so he knew when he could rotate 45 degrees between the exposures. The temperatures were well below freezing and if you look in the distance behind Canary Wharf you will see the snow on the hills.
