What effect does a slower shutter speed have on a moving subject?

A slower shutter speed has the distinct effect of capturing motion as a blur. When the shutter speed is reduced, it allows more light to hit the camera sensor over a longer period of time, which means that any movement occurring during this time will be recorded as a streak or blur in the image. This technique can be creatively used to convey a sense of speed or movement, making the subject’s motion more dynamic and visually interesting.

For instance, when photographing a moving car with a slow shutter speed, the car may appear sharp, while the background blurs, illustrating the speed and direction of its movement. This effect stands in contrast to faster shutter speeds, which tend to freeze action by capturing only a brief moment in time, producing a clear and crisp image of the moving subject. Thus, the option that indicates capturing motion as a blur accurately describes the outcome of using a slower shutter speed on a moving subject.
