I was working in London, and took a day off to walk around the city to be a tourist with my camera. I didn't have an agenda, it was just me and my camera. I knew I wanted to be near The River Thames because that's where the sights are.
While walking from the hotel to the river, I ended up taking a turn off the beaten path and ended up walking down this alley and at the end was this phone booth. Since this alley walkway was quiet, it was perfect to take my time and setup this shot.
