The lower the shutter speed, the more blurry the motion photo will be. With the 1/13 shutter speed the background and the person in motion are very blurry. In the 1/80 shutter speed it's much clearer but still a bit blurry right on the outline of the people in motion. In the 1/200 shutter speed both the background and person in motion are very clear and easily identifiable.
