The NiSi 55mm HUC PRO Nano IR ND8 Neutral Density Filter is specially designed to reduce the amount of light entering the camera by 3 stops. This filter is made from high-quality optical glass with nano coating to prevent losing any single bit of detail. Neutral density filters do not affect the coloration of the image and the 0.9 density provides a 3 stop reduction in light from entering the lens.
The ND Filter creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control the depth of field and convey movement in your images. The ND8 is widely used to capture water flow in seascape images and to create wider apertures when using flash outdoors.
By using neutral density filters the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shooting at a small aperture. The added the infrared protection coating layer to this filter which helps to eliminate the infrared light through the lens to bring back the natural color.
