The 82mm Natural Night Filter from NiSi is specially designed for night photography, making it an ideal choice for night scenes and astrophotography. Between mercury vapour, sodium, and Low CRI streetlights, there are many undesirable wavelengths of light that pollute the night sky. The glow from these can keep your camera from seeing the sky properly and effect your night images. To combat this, the Natural Night Filter works to block the most common wavelengths of light pollution. Made from high quality optical glass, it preserves every bit of detail and will not affect the colour of your image. It also features NiSi’s unique nano coating technology which reduces reflection on the surface of the filter to help with ghosting and flare. In addition, a protective layer makes it easy to wipe off water, dust, and oil from the filter without worrying about scratching your glass.
