- Neutral Density (ND) filters can reduce the intensity of light without appreciably changing its color. Classic ND filters have different f-stop reduction numbers and transmittance thus generated can be applied for different shooting conditions, such as portraiture, water falls, fountain etc.
- To allow video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause overexposure.
