Hoya 67mm Starscape Light Pollution Filter S-67INTENS

The Hoya 67mm Starscape Light Pollution helps photographers capture beautiful nighttime landscapes and pictures of stars and the Milky Way galaxy. The targets specific wavelengths of light emitted by common Sodium and Mercury-vapor street lamps and blocks a portion of that orange/yellow glow as it passes through the filter. The end result is a "cleaner" RAW file without the orange/yellow glow polluting your image. It allows you to color correct and enhance colors without needing to compensate for the "pollution". The effect can be dramatic or subtle depending on how strong the light source is and how much atmospheric haze is in the air. Remember, the filter is not adding blue or changing the color of the scene. It is literally stopping specific areas of the color spectrum from passing through the filter. The camera never sees that light or color.
