Featured here is a capture of downtown Riverton Utah made on a recent late night trip to the store for a gallon of milk. Contrary to the title, I was only driving 30 mph at the time of the photo.
To create this image, I wedged a tripod into the passenger seat of my car then aligned & focused the camera before leaving (safety!). I estimated an exposure time of 13 seconds at f/8. I then simply reached over and pressed the shutter release while driving.
I am farely pleased with the result. I only wished I had cleaned the mirror beforehand.
