Questions & Answers

FAQ

What is the main purpose of the 150x170mm Nano IR Reverse Graduated Neutral Density Filter?

The main purpose of this filter is to darken specific areas of an image, such as overly bright skies, while maintaining a normal, unaffected exposure in the remaining regions of the image. It's particularly useful for scenes that require a sudden transition from the foreground to the sky.

What is the advantage of the reverse edge on this filter?

The reverse edge places the darkest point of the filter at the transition area, making it an ideal tool for shooting directly at the light source. This is particularly useful when the harshest light is at the horizon and gradually tapers off toward the sky.

How does the filter handle infrared light?

The NiSi GND filters come with an infrared protection coating layer to eliminate the infrared light through the lens, ensuring the natural, true-to-life color of your images is preserved.

What is the material of the NiSi GND filters?

NiSi GND filters are crafted from high-quality optical glass, not resin, and feature a nano coating to ensure no detail is lost from your image.

Is the 150x170mm Nano IR Reverse Graduated Neutral Density Filter compatible with all camera lenses?

This filter is compatible with the NiSi 150mm filter system, making it an excellent choice for cameras with lenses that do not have a standard filter thread.

Professional quality filters

I have used high quality, professional level filters for over 20 years. I recently switched equipment that required much larger filters. I went with Nisi due to the versatility of the system. I am very impressed with the quality of the glass they use. when you put additional glass in front of your lens, you need it to be perfect. My impression is that Nisi filters are top of the line.

About NiSi Nano Grad IRND Filter

How does the 150x170mm Nano IR Reverse Graduated Neutral Density Filter, ND4 (0.6) 2-Stop enhance your photography This rectangular filter is expertly designed to darken specific areas of an image, such as overly bright skies, while maintaining a normal, unaffected exposure in the remaining regions of the image.

Unlike standard hard-edged GNDs, this reverse-edged filter features the darkest point at the transition area, making it an ideal tool for shooting directly at the light source. This is particularly useful when the harshest light is at the horizon and gradually tapers off toward the sky.

The 150x170mm Nano IR Reverse Graduated Neutral Density Filter is perfect for scenes that require a sudden transition from the foreground to the sky, with the brightest part of the scene near the horizon. This makes it an excellent choice for capturing landscapes with no elements protruding above the horizon, such as a serene seascape looking toward the open ocean.

NiSi GND filters are crafted from high-quality optical glass, not resin, and feature a nano coating to ensure no detail is lost from your image. They offer true-to-life color and do not affect the overall coloration of the image.

One common issue when using neutral density filters is the camera's vulnerability to infrared light, which can cast an unwanted red color to the photos when shooting at a small aperture. However, the NiSi GND filters come with an infrared protection coating layer to eliminate the infrared light through the lens, ensuring the natural, true-to-life color of your images is preserved.

The 150x170mm Nano IR Reverse Graduated Neutral Density Filter is compatible with the NiSi 150mm filter system, making it an excellent choice for cameras with lenses that do not have a standard filter thread. Enhance your photography with the precision and quality of the 150x170mm Nano IR Reverse Graduated Neutral Density Filter, ND4 (0.6) 2-Stop.
