The i1 Series Graduated ND16-8 Filter from Snake River Prototyping filter is ideal for unevenly-lit scenes to help darken a bright sky. It is a graduated neutral density filter that transitions from an ND16 (4-stop) filter on one edge to an ND8 (3-stop) filter on the opposite edge. The neutral density filter can help reduce rolling shutter artifacts by allowing your camera to use a slower shutter speed as well as allow for proper exposure of both your subject and the sky. The filter can be easily installed by screwing off the camera's UV filter and screwing on the Graduated ND16-8 Filter in its place. It works with the DJI Inspire or Osmo when using either with the Zenmuse X3 camera.
