NiSi 100x150mm Nano Soft-Edge Graduated IRND 0.9 Filter (3-Stop)
Key Features
  • 8x Filter Factor, 3-Stop
  • Reduce Exposure in Selective Areas
  • Soft-Edged Line of Transition
  • Allows Reduced Shutter Speed
The NiSi 100x150mm Nano Soft-Edge Graduated IRND 0.9 Filter is a rectangular filter that 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. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. 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-100-SGND0.9 Overview

The NiSi 100x150mm Nano Soft-Edge Graduated IRND 0.9 Filter is a rectangular filter that 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. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. 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.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide a high level of neutrality across the visible and infrared spectrums to eliminate color casts and ensure cleaner, truer blacks when using the NiSi 100 x 150mm Nano Soft-Edge Graduated IRND 0.9 Filter, one layer of 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 NiSi 100x150mm Nano Soft-Edge Graduated IRND 0.9 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

100x150mm 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.
Soft-edged line of transition between the dense and clear areas.
Useful for images that do not have a strongly defined transition between the sky and the foreground.
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.

Filter is excellent. Much easier to get it right in camera with this filter then have to play around with post processing. B&H's price was the best around.

Must Have filter, if you are Landscaper...

By Arup Kumar

This is one of the must have filter for any landscaper I believe. Newbies like me, realized the value of this filter after using it. It provided excellent control on Dynamic range without compromising with color cast. I managed to drop it successfully while using it on a rock and it survived leaving a scratch on the corner, and scratch is not affecting photography. I am very happy about it and planning to acquire Nisi complete range of filter set…

when I've used it its gotten the job done!

I've used this filter only 3 times, but I do like the gradient! when I want a specific subject to be well lit but I want to maintain a light exposed sky or harsh light, this filter does the job!

quality, no color shift, gentler transition than expected

By Jianing

The transition is much broader than I expected therefore not full 3 stops within the picture frame. It does have an advantage if the landscape requires such gentle transition effect. I had to order another 3-stop NiSi GND with hard-edge (keeping both for different applications). No color shift. A little worried about the possible scratches because the coating is on the surface instead of sandwiched between glasses. So far I no scratch but I only used it 2 times. From what I learned the coating is done by vacuum deposition. If so, I wonder if it is NiSi's preference to make more gentle transition (as evident in both soft and hard edge GND) or NiSi has technical limitation to produce a sharper edge. Overall quality seems very good and the packaging is very nice and sealed so you know you are not getting returned goods.

Great soft edge filter

This is a basic filter that I use in conjunction with a circular polarizer filter to help bring out sky and in particular cloud details. Like the fact that these NiSi filters are made with 2mm glass. Color rendition is excellent

Excellent transitions

Love NISI filters This is actually my second 3 stop Soft Grad. I'm using two in the NISI switch holder to set the grad effect on two different angles at the same time
