The NiSi 75x80mm Nano IR Neutral Density Filter – ND32000 (4.5) – 15 Stop is a Neutral density (ND) filter that uniformly reduces the amount of light entering the lens. ND Filters can enable greater motion blurring and image detail by allowing a large aperture and a slow shutter speed. ND filters are also helpful when the contrast between the highlights and shadows is too high to get a quality exposure. A 15 stops filter can be used to achieve very long exposures in the middle of the day and with this filter, exposures upward of 5 minutes can be achieved even during bright sunshine.
NiSi ND 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 ND 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 75x80mm filter is compatible with the NiSi M75 filter system.

Creating long exposures during the day using a 15 stop ND filter
Creating super long exposures during the day requires the use of neutral density filters capable of blocking a lot of light. During the brightest parts of the day the sunlight is very intense, with exposure times often around 1/500th secs and faster being required to expose correctly. A NiSi 15 Stop ND filter - also [...]
