The NiSi 58mm HUC PRO Nano IR Neutral Density Filter ND8 (0.9) 3 Stop 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 colouration of the image and the 0.9 density provides a 3 stop reduction in light from entering the lens.
The ND Filtercreates 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 isvulnerable to infrared light which will cast the unwanted red colourto the photos when shootingat 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 naturalcolour.
