The 100x150mmNano IR Soft Graduated Neutral Density Filter ND4 (0.6) 2 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 soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that feature trees, buildings, mountains and other elements that protrude into high 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 neutral density filter the camera isvulnerable to infrared light which will cast the unwanted red colour 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 colour.
The NiSi 150mm filter system is great for cameras with lenses that do not have a standard filter thread.
This 150mmx170mm filter is compatiblewith the NiSi 150mm filter system.
