Motion blur is a visual effect that occurs when an object moves quickly while a camera captures an image. This results in a streaking or smearing effect, where the moving object appears blurred in the direction of its motion. Motion blur can enhance the sense of speed and movement in photographs and videos. In photography and cinematography, motion blur can be controlled by adjusting the camera's shutter speed. A slower shutter speed allows more light to enter, capturing the movement over a longer period, while a faster shutter speed freezes the action, reducing the blur. This technique is often used creatively to convey dynamic action.
