ND Grad stands for the neutral density gradient filter. These are placed in front of the lens in order to make sure areas are not over exposed.They are optical filter that has a variable light transmission.Typically half of the filter is of neutral density which transitions, either abruptly or gradually, into the other half which is clear.

It can be used to darken a bright sky so that both the sky and subject can be properly exposed. ND filters can come in a variety of shapes and sizes and densities and can be used in all types of photographic applications from still photography, motion photography and scientific applications.

The filter comes in many types but can be separated into two basic categories:

  • Hard edge: A hard edge is used when there is an abrupt change in brightness
  • Soft edge: A soft edge is used when the light and dark portions are not distinctly separated
