The Nuances Graduated Filter Kit Hard Extr. by Cokin is a high-quality set of slide-in filters designed specifically for photographers who desire precise control over exposure in their images. This kit includes three different Graduated Neutral Density (GND) filters with strengths GND4H, GND8H, and GND16H, allowing for the darkening of the sky or other bright areas in a scene while keeping the darker areas unchanged. The Extreme Hard series offers a sharp transition boundary, making it ideal for landscape photography where a clear contrast between sky and land is desired. The filters are available in XL size and fit into the corresponding filter holders from Cokin, providing ease of use and flexibility in application. With these filters, photographers can enhance the dynamics of their shots while maintaining image quality.
