Marumi Digital High Grade ND Filters have been specially designed with Digital Photography. The filter helps to create a dynamic expression via a long exposure, or to prevent blown out highlights caused by over exposure. The Marumi ND Filter offers a light volume of 1/64th and the equivalent exposure value is 5 stops. The filter can reduce the light volume without any changes in hue, allow even a novice photographer who is unfamiliar with slow shutter speed or iris control to make a difference in their pictures.
Each filter uses a specially developed ultra-low reflection coating to minimize internal reflection off the cameras built-in CCD and CMOS Sensors. Other anti-reflect features include a special slim frame with satin smooth finish and a black ink process on the glass edge facilitates to eliminate flare. Neutral density filter reduce light volume, allowing the photographer to use slower shutter speeds under bright conditions, giving more control and creativity.
