The Hoya ND 16 reduces light by an equivalent of 4 stops. For photographers, ND filters provide precise control over the amount of light that enters the lens, allowing for greater creative control over exposure. For video content creators, ND filters are very helpful in adjusting shutter speeds to match frame rates while maintaining the depth of field of the footage. Thanks to the leading ACCU-ND technology, the image experiences no negative effects from color shifts that can occur due to inferior materials, poor quality control during manufacturing, or issues with the infrared range of the light spectrum. The latter problem is currently the most significant in photography and videography. With Hoya's exclusive ACCU-ND technology, a uniform reduction of light in the visible and IR spectrum is achieved. As a result, photographers need not worry about color shifts when using Hoya ND filters under various shooting conditions.
