Imported optical glass ensures the highest level of transparency. Eliminates unwanted reflections from non-metallic surfaces like water or glass, and glare from the sun. Description: Enhances colors and saturation, creating darker blue skies that make white clouds pop. The filter limits reflections from non-metallic surfaces like water and glass windows. Colors become brighter and clearer, and contrast is enhanced. Great for black and white photos too.
