The 39mm Circular Polarizing (CPL) lens filter from Urth is a high-quality screw filter specifically designed to enhance image quality in photography. This polarising filter reduces unwanted reflections from non-metallic surfaces, such as water or glass, while simultaneously boosting colour saturation, resulting in more vibrant and clearer images. The filter is ideal for landscape photography, as it increases the contrast between the sky and clouds and highlights details in shadow areas. With a diameter of 39mm, this filter is compatible with a variety of lenses and is easy to attach and remove. Its robust construction ensures a long lifespan and protects the lens from dust and scratches. The Urth CPL filter is a valuable addition to any photographic kit and is suitable for both amateur and professional photographers looking to expand their creative possibilities.
