One of the great things about shutter speed is that you have a lot of creative options when it comes to implying motion. Adding motion to a still photography can turn a regular photo into one that is dynamic and full of energy. Alternatively, you can create abstract motion and add a surreal mood to your images. Some examples that you may be familiar with include a speeding train passing by a train station or a trail of lights from the cars at night. The creative possibilities with using slow shutter speed are endless.
