NiSi Cinema Yellow Light Blocker

NiSi Cinema 4×5.65” Yellow Light Blocker (Natural Night)

The NiSi Cinema Yellow Light Blocker (Natural Night) is designed to reduce the appearance of light pollution in video or images that include the night sky and illumination from artificial light sources.  Light pollution occurs in areas of the night sky that are above or near concentrated and intense sources of artificial light such as cities. These light sources can include exterior and interior lamps for commercial or residential buildings, brightly lit advertisements as well as sports and entertainment venues. Additionally, artificial lights clustered together can become difficult to discern individually. Light pollution from these “cluttered” sources can become a source of distraction within an image and can resemble overexposed areas of glare.

When used, the NiSi Cinema Yellow Light Blocker (Natural Night) can improve the results of nighttime images by blocking the yellow light from sodium-vapour lamps, mercury-vapour lamps, or low Color Rendering Index LED’s, conventional light sources within urban areas. By preventing the dominant wavelengths of light associated with the colour of those lamps from being recorded, the visibility of astronomical objects is increased, and where they appear, artificial light sources are more clearly defined with less glare and improved contrast.
