Definition & Meaning of "motion blur"

What is "motion blur"?

Motion blur is a visual effect in photography where moving subjects appear streaked or smeared due to their movement during the exposure. This happens when the camera's shutter remains open while the subject moves, capturing the motion as a blur in the final image. Motion blur can convey a sense of speed and movement, adding a dynamic quality to the photograph. It is commonly used in action shots, such as sports or dance, to emphasize motion and create a sense of energy.
