This effect can be obtained when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. \u003cbr\u003e \u003cbr\u003e 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 such as billboards, streetlamps, as well as sports and entertainment venues. Together, they can result in a type of light pollution known as skyglow, where individual stars, the Milky Way, and other astronomical features in the night sky are obscured. Additionally, artificial lights clustered together can become difficult to individually discern. Light pollution from these \"cluttered\" sources can become a source of distraction within an image and can resemble overexposed areas of glare. \u003cbr\u003e \u003cbr\u003e When used, the NiSi 95mm Natural Night Filter can improve the results of nighttime images by blocking the yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs, common light sources within urban areas. By preventing the dominant wavelengths of light associated with the color of those lamps from being recorded, the visibility of astronomical objects is enhanced, and artificial light sources are more clearly defined with less glare and improved contrast. \u003cbr\u003e \u003cbr\u003e This NiSi 95mm Natural Night Filter is constructed from optical glass for clarity as well as color fidelity. Each glass surface includes one layer of nano coating. The nano coating associated with this filter results in an improved beading effect when in contact with water or oil for greater cleaning efficiency. \u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdl\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eReduces the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources\u003c\/li\u003e \u003cli\u003eFor cameras with daylight film installed, or a digital camera system with its daylight white balance setting selected\u003c\/li\u003e \u003cli\u003eBlocks the yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs, common light sources within urban areas\u003c\/li\u003e \u003cli\u003eEnhances the visibility of astronomical objects, and where they appear, artificial light sources are more clearly defined with less glare and improved contrast\u003c\/li\u003e \u003cli\u003e1.5 to 2.8x filter factor reduces exposure by 0.6 to 1.5 stops\u003c\/li\u003e \u003cli\u003eConstructed from optical glass for clarity\u003c\/li\u003e \u003cli\u003eEach glass surface includes one layer of nano coating that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency\u003c\/li\u003e \u003cli\u003eAluminum-alloy filter ring for durability while remaining lightweight\u003c\/li\u003e \u003cli\u003e95mm front filter threads allow for use with other filters\u003c\/li\u003e \u003cli\u003ePlastic case included for storage and transport\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003e In the Box \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e NiSi 95mm Natural Night Filter \u003c\/div\u003e \u003c\/div\u003e \u003cli\u003eFilter Case\u003c\/li\u003e \u003cli\u003eLimited 1-Year Warranty\u003c\/li\u003e \u003cdiv\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch3\u003eNiSi NIR-NGT-95 specs\u003c\/h3\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eType\u003c\/td\u003e \u003ctd\u003eBroad-band light pollution reduction filter\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSize\u003c\/td\u003e \u003ctd\u003e95 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDensity\u003c\/td\u003e \u003ctd\u003e0.2 to 0.45\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFilter Factor\u003c\/td\u003e \u003ctd\u003e1.5 to 2.8 (0.6 to 1.5 stop)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMulti-Coated\u003c\/td\u003e \u003ctd\u003eNo\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eEffect\u003c\/td\u003e \u003ctd\u003eReduces the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources by blocking yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eConstruction\u003c\/td\u003e \u003ctd\u003eH-K9L optical glass\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFront Filter Thread Size\u003c\/td\u003e \u003ctd\u003e95 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFront Lens Cap Size\u003c\/td\u003e \u003ctd\u003e95 mm\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth colspan=\"2\"\u003e \u003ca\u003ePackaging Info\u003c\/a\u003e \u003ca\u003e\u003c\/a\u003e \u003c\/th\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePackage Weight\u003c\/td\u003e \u003ctd\u003e1.0 lb\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBox Dimensions (LxWxH)\u003c\/td\u003e \u003ctd\u003e4.5 x 4.5 x 1.0\"\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
