The NiSi Natural Night Filter is designed to reduce or eliminate the appearance of light pollution from images and video. For best results, a digital camera system can be used with the daylight white balance setting selected.
The quality results of images can be improved by blocking the yellow light from sodium-vapour lamps, mercury-vapour lamps, or Low Colour Rendering LED lamp.
