The Urth 100 x 150mm Reverse Graduated ND8 (3 Stop) Filter is a high-quality graduated neutral density filter specifically designed for photography. With a size of 100 x 150 mm, it is ideal for use in various lens holders. This type of filter allows for a smooth transition from transparent to a darker area, which is particularly useful for balancing the contrast between the sky and landscape in landscape photography. The ND8 (3 Stop) filter reduces the amount of light hitting the sensor to avoid overexposure while preserving colour depth and details in the brighter areas. The reverse graduated design of the filter ensures that the transition from clear to dark in the upper half of the image is smooth, promoting a natural and harmonious composition. This filter is an essential tool for photographers looking to expand their creative possibilities and enhance image quality in challenging lighting conditions.
