Perfectly Balanced Landscapes Our professional Hard Graduated ND8 (3 Stop) Filter Plus+ provides a fixed 3 f-stop light reduction for balanced exposure and better dynamic range in hard graduated light conditions. By blocking 3 f-stops of light from half your image, you can balance your exposure when the foreground is darker than the background - such as shooting landscapes in the mountains. The hard graduation creates a natural blending of light.Our Plus+ range features 20 layers of nano-coating providing easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction. For best results, use our Hard Graduated ND8 Plus+ with lenses of focal lengths 35mm and above. World's Best Glass Made with world leading German SCHOTT.
