The NiSi 75x100mm Nano IR Reverse Graduated Neutral Density Filter – ND4 (0.9) – 3 Stop 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. Reverse edged GNDs are similar to hard-edged GNDs except that the darkest part of the filter is at the transition point. These filters have a specific use for shooting at the light source where the light is harshest at the horizon and tapers off toward the sky. This type of filter is most appropriate for scenes which have a sudden transition from the foreground to the sky with the brightest part of the scene near the horizon. Most commonly, this would include landscapes with no elements protruding above the horizon such as a seascape looking toward the open ocean. They can be used shooting into the direct light where a sharp transition is needed.
NiSi GND filters do not affect the colouration of the image, offer a true to life colour and are made from high-quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red colour to the photos when shooting at a small aperture. NiSi GND filters have an infrared protection coating layer to eliminate the infrared light through the lens to bring back the natural true to life colour.
The NiSi M75 filter system is great for compact and mirrorless cameras with lenses that have a standard filter thread from 40.5mm to 67mm.
This 75x100mm filter is compatible with the NiSi M75 filter system.

When to use a reverse graduated neutral density filter
Graduated neutral density filters come in several different varieties - the most common of them being soft, medium, hard and also reverse graduated ND filters. Each of them has different benefits on different types of scenes and better times to use them. One of the filters we get asked the most questions about is the [...]

What order do I insert neutral density filters into my NiSi holder?
When you first start to use a square neutral density filter system it can be a little confusing to understand the correct order to insert filters into the holder. There is a specific order which ND filters are designed to be placed in to prevent light leakage and other image quality issues caused by bright, [...]

Optical Glass vs Resin Neutral Density Filters – Which Is Best?
When it comes to optical performance in photography, the quality of lenses and filters being used plays a huge role in the overall quality and sharpness of the images being produced. Quality camera lenses are finely tuned pieces of equipment containing multiple glass elements which are aligned to direct the path of light rays as [...]
