The NiSi natural night filter removes unwanted light pollution in night photos by cutting out very specific wavelengths of light produced by artificial light sources. It removes all yellow light produced by sodium-vapor lamps, mercury-vapor lamps and low-CRI LED's. This ensures that night-time images are colour-accurate, sharp and rich in contrast. This unique new filter is an indispensable tool for any serious cityscape shooter.
This filter drastically improves detail and contrast around bright light-sources.
This filter is also available in a circular screw-in version.
Please note that the Natural Night filter is not compatible with the Lee holders - it slides out as there is not enough friction between the filter and the holder. You can solve the problem by applying some insulation tape to the edge of the filter, should you want to use it with your Lee holder.
