I just got back from a month in Europe and spent the last weekend in London, England. I had a room on the 9th floor of the the Hilton on Park Lane in London which had some pretty amazing views, especially from the bar on the 25th floor. I shot this out of my window on the 9th floor using a Canon 60D and two GoPro HD cameras.
