The Urth 77mm ND16 (4 Stop) lens filter is a high-quality neutral density filter specifically designed for photographers and videographers looking to expand their creative possibilities. With a diameter of 77 mm, this screw filter easily attaches to most lenses. The ND16 filter reduces the amount of light hitting the sensor by 4 stops, allowing for longer exposure times in bright lighting conditions or wider apertures to achieve a shallower depth of field. This is particularly useful for capturing motion, such as flowing water or moving subjects, as it creates a smooth blur. The filter is made from high-quality materials to ensure optimal image quality and minimise unwanted reflections. It is a valuable addition to any photography or videography kit and offers versatile applications in various lighting conditions.
