Shutter Photo

This is my best shutter photo. We were assigned to take a photo showing the motion or movement in objects. I found it difficult to stay stationary and capture moving objects so I had an idea to do it while the car was moving so that everything is effected by the movement. The element in this photo would be movement obviously. The principle would have to be Space because your eye kind of follows the car as it's moving. It took a really long time to get a good photo but I'm very happy with this one.
