DJI ACTION 2 FILTER （ND8/16/32/64）(PROFESSIONAL)

The ND filter also called the Reducing Light filter, or Neutral Density filter reduces the amount of light in very bright conditions so that the camera can choose the correct exposure value and avoid excessive exposure.
It also improves the color saturation of the picture, makes the picture more transparent and alive. You can also use a slow shutter speed to shoot some special effects, such as a mist of water, a light track at night, etc. When you shoot video in direct sun exposure, you can reduce the shutter speed by subtracting the lens, so that the video has the appropriate motion blur and looks balanced.
