ND varies from ND2 (1 stop) to ND400 (9 stops). Neutral density filters appear gray and have no effect on color. Digital Water Proof and Scratch Resistant Multi-coated glass for optical clarity and color fidelity. Wide angle construction insures no vignette on wide-angle lenses. A convenient index scale on the filter ring makes exposures repeatable and exact.
