The NiSi 100mm100mm Nano IR Neutral Density Filter – ND4 (0.6) – 2 Stop is a Neutral Density (ND) filter that 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 a quality exposure. The ND4 2 Stop is commonly used for waterfalls and capturing water flow at shutter speeds from 0.25 seconds to 2 seconds.
NiSi ND filters do not affect the coloration of the image, offer a true to life color and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shooting at a small aperture. NiSi ND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true to life color.
The NiSi 100mm filter system is great for cameras with lenses that have a standard filter thread from 49 mm to 95mm.
This 100mmx100mm filter is compatible with the NiSi 100mm filter system.
