This photo was taken at the Winter Wonderland attraction at Hyde Park, London. The ride took ages to get going because more and more people kept getting on! I used a slow shutter speed to blur the carriages of the ride as the sped round at a high speed.
F-Stop: f/22 | Exposure: 0.6s | ISO Speed: 400
