ND filters are important for filmmakers and photographers because they allow accurate control of the amount of light passing through objectively, providing greater creative control over exposure. For filmmakers, this means appropriate lock speed while maintaining the desired depth of field. For photographers, this means that they can use longer exposure time or reach narrow depth in severe sunlight.
