Photorepublik Pro HD filters are made from high-quality Schott glass and feature an expertly machined attachment ring. The PhotoRepublik Pro HD Circular Polarizer reduces reflection and glare created by polarized light. Light becomes partially polarized due to scattered particles in the atmosphere, creating a haze on blue skies, and reflections.

The effect is strongest at a 90 angle to the sun, and enhance the colour saturation of you images.
