The Cokin NUANCES X-Pro Series Soft-Edge Graduated Neutral Density 0.9 Filter is a filter designed for use with a Cokin X-Pro Series Filter Holder. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens.

Cokin NAUNCES filters are constructed from tempered Schott B270 glass and feature nano-metallic alloy film coatings on both sides of the filter surface to attenuate infrared light and maintain true color fidelity even when stacked with other Cokin NUANCES filters. Multi-layered coatings further help to reduce surface reflections for increased contrast and clarity.
