Cokin NUANCES Extreme Z-Pro Series Soft-Edge Reverse-Graduated ND Filter (4 x 5.65", 2- to 1-Stop)

This filter achieves its effect with a 0.6 band of density across its center region that provides a 2-stop reduction in light from entering a lens. This band extends in both vertical directions which tapers to a 0.3 density that provides a 1-stop reduction in light at the edge above it. Directly below the 0.6 band of density, it tapers to clear, with a soft-edged line of transition before the clear area.

The placement of a 0.6 band of density that tapers to a density of 0.3 above it with a clear area directly below, allows the Cokin NUANCES Extreme Z-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.6 to 0.3 Filter to match the positioning of the sun when it is at, or immediately above the horizon. In such instances, the sun can appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created that is more prominent on both sides of the sun than above it. This pattern of brightness corresponds to the density pattern on the Cokin NUANCES Extreme Z-Pro Series Soft-Edge Reverse-Graduated Neutral Density 0.6 to 0.3 Filter. The soft-edged line of transition in this reverse, graduated neutral density filter is useful for soft transitions between the sky and land, while the 2-stop to 1-stop gradation is applicable to multiple regions of brightness within the sky.

Cokin NUANCES Extreme filters are constructed from tempered, shock-resistant glass and feature nano-metallic alloy film coatings on both sides of the filter surface to attenuate infrared light while maintaining true color fidelity, even when stacked with other Cokin NUANCES or NUANCES Extreme filters. Anti-glare coatings further help to reduce surface reflections for increased contrast and clarity, while additional hydrophobic coatings result in an improved beading effect when in contact with water for greater cleaning efficiency. Additionally, Cokin NUANCES Extreme filters feature C-shaped edges. This rounded edge shape resists chipping to further enhance durability.
