ND 3,6,9 (Graduated)

ND (Neutral Density) Graduated Filters are used to reduce the amount of light entering the lens while preserving color balance. They have a gradual transition from dark to clear, which helps to manage exposure differences between the sky and the foreground. ND 3, 6, and 9 filters offer varying degrees of light reduction, with ND 3 providing a 1-stop reduction, ND 6 a 2-stop reduction, and ND 9 a 3-stop reduction. They are ideal for landscape photography, balancing exposure in high-contrast scenes, and achieving smoother motion in video.
