• Reduces the amount of light reaching the film when it is not painted (ND8 reduces exposure by 3 levels. ND16 reduces exposure by 4 levels. ND4 reduces exposure by 2 levels). Can reduce the amount of light in very bright conditions, so the camera can choose the right exposure and avoid overexposure. Increases the color saturation of the image, making it more transparent and vivid. Can use a slow shutter speed to capture special effects such as water mist, night light tracks, etc. When shooting video directly in sunlight, you can use ND filter to lower the shutter speed so that the video has the right motion blur and looks balanced.
