The Urth 72mm 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 screw-on filter combines the features 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 water surfaces or nature scenes. On the other hand, the ND64 filter allows for a reduction in the amount of light hitting the sensor, enabling longer exposure times and better control over depth of field. With a diameter of 72 millimeters, this filter is compatible with a variety of lenses and is easy to attach. The combination of these two filter types in one product makes it a versatile tool for anyone looking to expand their photographic and filmmaking skills.
