Gradual left gradual right | I took this just after midnight when driving through a massive thunderstorm. I had my camera out trying to capture lightning over a freight train, but it never materialized. Rather than putting the camera away, I left it on the dash and took a few 10-second exposures on the way home. This was the last and only 20-second exposure. I focused the camera on the road in front of me at a stoplight and then released the shutter after driving for a while. It just so happened that I made a gradual left and then right while taking this exposure, making the street lights and green lights look like they slide across the horizon. I’m not sure where the reds come from, but I found them in post-processing.
