Cokin Nuances Clearsky Light Pollution Filter, 77mm

The Light Pollution filters block specific wavelengths of urban lights such as the sodium and mercury vapor lamp spectrums. The yellow and orange glow of street lights is removed for urban photography at night, and the contrast of the sky is enhanced for astrophotography by darkening the gradient of the sky background, highlighting the stars or the Milky Way. Ideal for Night CItyscape, Nightscape & Astrophotography.
