The Urth 43mm Circular Polarizing (CPL) + ND64 Lens Filter (Plus+) is a high-quality lens filter specifically designed for photographers and videographers looking to enhance their shots. This filter combines the properties of a circular polarizing filter with an ND64 filter, offering a wide range of creative possibilities. The circular polarizing filter reduces reflections and enhances color saturation, which is particularly beneficial for capturing images of water surfaces or in nature. On the other hand, the ND64 filter decreases the amount of light hitting the sensor, allowing for longer exposure times or a wider aperture without compromising image quality. With a diameter of 43 millimeters, this screw-on filter is easy to attach and fits a variety of lenses. Using this filter can help improve image composition and enhance the visual impact of your shots. It is a valuable addition to any photography gear.
