Physical cameras expose their film for some period of time, during which moving objects in the scene may change their position, orientation, size, or shape. Moving objects leave a blurry “trail” on the film. In particular, the edges of moving objects become semi-transparent because the object was only occupying the blurred region for some fraction of the shutter open time. Motion blurring simulates these effects.
