BH #NIHGNDLF0.9 • MFR #NIP-150-HGND0.9
NiSi
NiSi 150 x 170mm Nano Hard-Edge Graduated IRND 0.9 Filter (3-Stop)
Key Features
  • 8x Filter Factor, 3-Stop
  • Reduce Exposure in Selective Areas
  • Hard-Edged Line of Transition
  • Allows Reduced Shutter Speed
The 150 x 170mm Nano Hard-Edge Graduated IRND 0.9 Filter from NiSi has a rectangular shape and helps darken specific areas of an image, such as bright skies, while allowing for normal, unaffected exposure in other parts of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature a prominent horizon, or any hard transition between the sky and land. 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 the lens.

NiSi NIP-150-HGND0.9 Overview

The 150 x 170mm Nano Hard-Edge Graduated IRND 0.9 Filter from NiSi has a rectangular shape and helps darken specific areas of an image, such as bright skies, while allowing for normal, unaffected exposure in other parts of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature a prominent horizon, or any hard transition between the sky and land. 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 the lens.

Constructed from optical glass for clarity as well as color fidelity, this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. To provide a high level of neutrality across the visible and infrared spectrums to eliminate color casts and ensure cleaner, truer blacks, NiSi Optical Nano Coating is applied to each of this filter's surfaces. The Nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency. This filter is 2mm thick and fits most filter holder systems that are 150mm wide.

150 x 170mm graduated neutral density filter darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected.
8x filter factor provides up to a 3-stop reduction of light in selective areas.
Hard-edged line of transition between the dense and clear areas.
Useful for images that feature horizons, or any hard transition between the sky and land.
Filter does not affect coloration of the image and is ideal for use with other filters.
Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
Nano coating provides an improved beading effect with water or oil for more efficient cleaning.
Constructed from optical glass for clarity.
Leatherette pouch included for storage and transport.
