Cokin X-Pro Series Graduated Neutral Density 0.9 to 0.3 Filter (3 to 1-Stop)

This Cokin X-Pro Series Graduated Neutral Density 0.9 to 0.3 Filter is designed for use with a Cokin X-Pro Series Filter Holder. Its 0.9 to 0.3 density creates a darkening of the entire image that is graduated, allowing you to suppress specific areas of an image such as very bright skies, while providing a similar, but reduced effect in other regions of the image that can benefit from a more moderate reduction in exposure, such as reflecting water or sand. The Cokin X-Pro Series Graduated Neutral Density 0.9 to 0.3 Filter is densest at the edge with up to a 0.9 density that tapers to a 0.3 density at the other edge. This filter's 0.9 to 0.3 density range corresponds to a reduction of light from entering a lens by three stops to one stop.
