150x150mm ND Filters

NiSi Neutral Density Filters uniformly reduces the amount of light entering the lens.  ND Filters can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed.  

ND filters are also helpful when the contrast between the highlights and shadows is too high to get quality exposure. The NiSi 150mm range features 3 Stop, 6 Stop 10 Stop, and 15 Stop.
