In Toulouse, France, the metro train is driven by computers. This allows passengers to go to the front of the train and see the tracks ahead. Photographer Éole Wind decided to see what a long exposure would look like as the train went around a bend.
Leaving the shutter open for 5 seconds (f3.5, ISO 100, 22 mm) produced the amazing image you see above which Wind states had no post-effect work done to it. It really conveys a sense of speed and motion, a great capture and well executed!
