The NiSi Natural Night for DJI Mavic Pro and Phantom Pro/Advance are designed to film at night removing the light pollution.
When you are filming on the street at night the mercury vapour, sodium, Low CRI streetlights, "paint" the objects with an unnatural light and glow the sky, this cause an overexpose areas that can't be recovered in post-processing, also the colors can't be recovered in post due to the hard unnatural color of the streetlights.
Dur to this, NiSi has created the Natural Night Filter to block the most common wavelengths of light pollution. Like the rest of the NiSi line, this filter is made of high quality aluminium and optical glass.
The NiSi Natural Night Filter with the NANO Coating technology has a multi-layer coating that reduces reflection on the surface of the filter avoiding flares. It also includes a protective layer that makes it easy to wipe off water, dust, and oil from the filter without worrying about scratching your glass. The NANO Coating process achieves this without loss in sharpness, it's possible to film in 4K with an incredible definition.
