The Urth 77 mm Soft Graduated ND8 Lens Filter (Plus+) offers a fixed 3-stop light reduction over half of your frame, allowing for a balanced exposure gradient and an extended dynamic range with smooth light transitions. This professional filter blocks 3 stops of light from one half of your composition, enabling you to balance the exposure when foreground elements are darker than the background, which is particularly useful in mountain landscapes and similar scenarios. The soft gradient creates a natural transition effect between the filtered and unfiltered areas. Made from high-quality German B270 SCHOTT optical glass, this filter features 20 nano-coating layers that facilitate cleaning while providing excellent protection against water, oil, and scratches. The advanced coating system ensures higher maximum light transmission and a more consistent transmission curve for precise light reduction performance. The ultra-thin housing design prevents vignetting, while the robust Magnalium construction offers long-term reliability. The double-threaded design allows for stacking filters or attaching screw caps. This filter helps photographers capture more detail and depth in both bright and shadowed areas, resulting in more balanced, detailed landscape photographs with an extended dynamic range. The product reflects Urth's commitment to environmental responsibility through conscious design practices and sustainable material selection.
