The 46mm Circular Polarising (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 enhancing colour saturation, resulting in more vibrant and clearer images. The filter is ideal for landscape and architectural photography, as it increases the contrast between the sky and clouds and highlights details in shadow areas. With a diameter of 46mm, this filter is compatible with a variety of lenses and is easy to attach and detach. 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, allowing photographers to achieve creative effects and significantly improve image quality.
