The NiSi 100x150mm Nano IR Soft Graduated Neutral Density Filter – ND32 (1.5) – 5 Stop is a rectangular filter that helps to darken specific areas of an image, such as bright skies while allowing for a regular, unaffected exposure in the other regions of the picture. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged transition line between the thick and clear areas. A neutral density filter with a soft-edged linechange is beneficial for images that feature trees, buildings, mountains and other elements that protrude into the skyline.
NiSi GND 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. In addition, 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 colour.
The NiSi 100mm filter system is great for cameras with lenses with a standard filter thread from 49 mm to 95mm.
