The 84 x 100mm Cokin NUANCES Extreme P Series Center-Graduated ND Filter is designed for use with a Cokin P Series Filter Holder. It can be applied to darken the sky, specifically along the horizon during a sunrise or sunset, while allowing for a normal, unaffected exposure in the other regions of the image.

This filter achieves its effect with a 0.9 band of density across its center region that provides up to a 3-stop reduction in light from entering a lens. The band of density extends approximately 0.8" in both vertical directions before tapering to clear below and above, with soft-edged lines of transition before the clear areas. The clear areas then extend approximately 1.6" until they meet the top and bottom edges of the filter.

A narrow 0.9 band of density with larger clear areas directly above and below it allows the Cokin NUANCES Extreme P Series Center-Graduated Neutral Density 0.9 Filter to specifically match the positioning of the sun when it is at, or immediately above, the horizon. In such instances, the sun will appear closer to the center of an image as opposed to the upper edge, and an increase in brightness is created which is much more prominent on both sides of the sun than either above or below it. This pattern of brightness corresponds to the density pattern on the Cokin NUANCES Extreme P Series Center-Graduated Neutral Density 0.9 Filter. The soft-edged lines of transition in this filter are useful for images that have features alongside the sun that cannot be confined within the band of density.

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.

Q: 1. What is the resolving resolution on these filters?

A: where did ou read about this? seems not related

Q: 2. If I got these filters for the bmpcc 4k, would I need to use an IR cut filter with them or do these filters already cut IR to prevent color shifting?

A: NiSi states that the filters in the NiSi 100 x 100mm Solid Neutral Density Extreme Filter Kit use their IR technology, i.e. the coating that blocks infrared light, and therefore eliminates the risk of magenta color cast.

Q: 3. What type of adapter ring is needed for Cokin BPE01 Filter holder?

A: It will depend on what filter thread is on your lens. Find the filter thread for your lens and choose the size of the adapter ring here https://bhpho.to/3e43Tk6

Q: 4. Can other filters screw on to the Nano filter to stack filters?

A: Unfortunately this filter is too thin to stack any more filters on top of it.

Q: 5. Will it fit in Lee 100 and Nisi V6 filter holders?

A: Yes, they are all 2mm thick and will work with each other.

Q: 6. Can I use this wallet for the 100mm format hitech system ?

A: The filters will be the same size so it should fit other 100mm filters.

Q: 7. What are the filter dimensions? 100x100 mm?

A: Cokin*

Q: 8. Will format Hitech 4x6 filters work with this?

A: These items were purchased as a gift. I never used them.

Q: 9. This comes with some foam gaskets but don't the filters already have these attached? If so, what's the point of including extras.

A: Those are replacement foam gaskets in case the others wear out.

Q: 10. Will this filter fit into a tiffen 4x4 holder?

A: This filter is a 2mm filter. The Tiffen works with 4mm filters. This filter would be at risk of falling out.
