The Hoya ND 64 reduces light by an equivalent of 6 stops. For photographers, ND filters provide precise control over the amount of light entering 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, images do not suffer from negative effects due to color shifts that can occur from inferior materials, poor quality control during manufacturing, or issues with infrared light spectrum leakage. The latter issue is currently the most significant in photography and videography. With Hoya's exclusive ACCU-ND technology, a uniform reduction of light in both the visible and IR spectrum is achieved.
