The NiSi NID-PHTM4-NGT is a Natural Night filter designed to fit the lens of a DJI Phantom 4 drone. Natural Night filters are yellow light blockers that block most of the influences of light pollution, an effect best observed in nighttime cityscape photography and videography. The PHTM4-NGT will fit both the Standard Phantom 4 and Phantom 4 Pro drones.
