Neutral density (ND) filters are the most demanded and essential type of photographic filters because of several reasons. For photographers ND filter means precise control of the amount of light passing through the lens for greater creative control over exposure. For video content creators ND filters helps much to set shutter speeds to match the frame-rate while maintaining the depth-of-field of the footage.
