[공통적인 문제점들] Too long exposure: image has become blurred because of hand shaking or subject moving too fast. [규정] Motion blur should have a purpose, most often to emphasize motion. [토의] "Movement control" refers to the manner in which motion is represented in the image. Motion can be frozen or blurred. Neither is better over the other by itself – it's representation that matters. Movement is relative within the objects of the image. For example, photographing a race car that appears frozen in relation to the background does not give us a sense of speed or motion, so technique dictates to represent the car in a frozen manner but with a blurred background, thus creating a sense of motion. This is called "panning". On the other hand, representing a basketball player in a high jump frozen in relation to everything else, due to the "unnatural" nature of the pose may well be a good photograph.
