COKIN Nuances Clearsky Light Pollution Filter Diameter 95 mm

Light pollution filters block certain wavelengths of street lighting, such as the emission spectra of sodium and mercury vapour lamps. In city photography, the yellow-orange hue of street lamps is greatly reduced. In astrophotography, the contrast of the sky is increased by obscuring the gradient of the sky background, causing the stars or the Milky Way to stand out.
