                    The technical details behind this filter                    
NiSi Explorer Series 100x100mm Nano IR Neutral Density Filter - ND8 (0.9) - 3 Stop is part of the Explorer Series made for adventure. The filters feature a special glass hardening process that makes them double the strength of a typical glass filter. The Explorer series are much less prone to accidental breakage and perfect for active photographers. Neutral density (ND) filters uniformly reduce 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 ND8 3 Stop is commonly used for waterfalls and capturing water flow at shutter speeds from 0.5 seconds to 2 seconds. NiSi ND filters do not affect the colouration of the image, offer a true to life colour, and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. By using a neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red colour 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 colour. The NiSi Explorer Collection is made from B270 tempered glass. It features the same Nano coating process as our optical glass filters. This filter is tempered and hardened making it much less prone to accidental damage but this does not mean it is unbreakable. After a long period of time, the hardening may decline. It is compatible with the NiSi 100mm system.
