JJC 55mm Natural Night Filter F RN55

Purpose and Function

The JJC F RN Natural Night Filter 55mm is designed to reduce light pollution in photos and videos captured during night scenes. It enhances color saturation to provide natural and vivid color reproduction, improving the clarity and contrast of night sky images.

Light Pollution and Its Effects

Light pollution commonly occurs near concentrated artificial light sources such as city streetlamps, commercial and residential building lights, illuminated billboards, and sports venues. This results in skyglow, which obscures stars, the Milky Way, and other astronomical features in the night sky.

Filter Characteristics and Benefits

• Filters out specific light pollution wave bands, mainly reducing yellow light emitted by sodium vapor lamps, mercury vapor lamps, and low CRI LEDs in urban areas.
• Maintains high transmittance in nebular emission lines to preserve astronomical details.
• Enhances image purity, star clarity, and overall transparency.
• Improves color depth and vividness, making skies appear bluer and sunsets more layered and natural.

Construction and Coatings

• Made from high-definition optical glass with nano coating technology.
• Features 9 layers of coating on each glass surface, providing anti-scratch, anti-static, anti-fingerprint, oil, and water resistance.
• Frame constructed from high-quality aluminium alloy, only 3 mm thick to prevent vignetting.
