NiSi Square Nano IR GND Hard 150x170mm – Hard-edge Graduated Neutral Density for Defined Horizons

Designed for landscape photographers

This NiSi Square Nano IR GND Hard 150x170mm filter suits landscape photographers who work with scenes that have a clear separation between bright and dark areas. You can use it where the horizon or the line between sea and sky is sharply defined. The hard-edge design provides a visible boundary between the transparent and dark areas, so you know exactly where the gradient begins and ends.

Optical construction and coatings

The filter is made from high quality optical glass (not resin). In addition, NiSi applied nano coatings to both sides to protect details and to repel water and oil. An infrared protection coating reduces the unwanted red cast that can appear when shooting at small apertures by eliminating infrared light passing through the lens.

Practical handling and use

You can reposition this filter within a compatible holder to recompose your image and achieve the best result. Because it is a neutral density type, it does not affect the coloration of the image. It also features design characteristics that minimize reflection and color cast while maintaining high definition and avoiding vignetting.

Available densities

• 2 stop (0.6)
• 3 stop (0.9)

FAQ

• Question: Can I use this filter for seascapes with a clear horizon?
  Answer: Yes. The hard-edge GND shows a clear boundary between dark and transparent areas, making it well suited for horizons and other scenes with a distinct separation.
• Question: Will this neutral density filter change my image colors?
  Answer: No. The filter is designed as a neutral density type and does not affect the coloration of the image. In addition, NiSi's infrared protection coating helps restore natural color by reducing infrared-induced red cast.
• Question: Is the filter glass or resin?
  Answer: The filter is made from high quality optical glass (Environmental Optical Lens glass H-K9L), not resin.
• Question: What coating and handling features does it have?
  Answer: It has nano coating on both sides for detail protection, water and oil repellency, plus an infrared protection coating. You can also reposition the filter inside a holder to recompose your shot.
• Question: Which density options are available for this size?
  Answer: For the 150x170 mm size, you can choose 2 stop (0.6) or 3 stop (0.9) maximum effect.
