The NiSi Explorer Collection 150x170mm Nano IR Medium Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop is part of our Explorer Series for 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.
The NiSi Explorer Collection 150x170mm Nano IR Medium Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition is particularly useful for images that feature buildings, small mountains, and other elements that protrude high into the skyline. The transition zone of a medium is 40% smaller than a Soft GND and is wonderful for shooting at sunrise and sunset.
NiSi GND 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 a 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 GND 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 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.
This 150x150mm filter is compatible with the NiSi 150mm filter system.
