This can create more natural motion blur in moving ground detail, vehicles, waves, and subjects while preventing exposure from being controlled only by an extremely fast shutter. The filter …
The 180-degree shutter rule is a practical starting point for controlling motion blur in video. It links exposure time to frame rate so moving subjects retain a familiar balance between definition and blur. Bright conditions can make that exposure time difficult to maintain. An ND filter reduces incoming light so the camera can preserve the …
