Motion blur is a visual effect that occurs when an object moves quickly while a camera captures an image. Instead of appearing sharp and clear, the moving object appears smeared or streaked, creating a sense of speed and movement. This effect can be seen in photographs, videos, and animations. In photography, motion blur can be intentionally used to convey action or dynamism. By adjusting the camera's shutter speed, photographers can control the amount of blur, allowing them to highlight movement in a scene. This technique is often used in sports photography and action shots to enhance the viewer's experience.
