Taken from the top deck of a double decker bus while passing through one of Hong Kong's tunnels at night. A small tripod was used with the camera close to the window to minimise reflections. This one came out fairly sharp seeing it was a 2 second exposure (see here for what happened when we hit a bump). I like the tail lights reflected off the walls and also the halo effect of the car lights. Only a levels and curves adjustment was done in Photoshop.
