The 9-stop, 100 x 100mm NiSi Nano IRND Filter 100x100mm 9-Stopis an ND filter with a 512x filter factor that provides a 9-stop exposure reduction. Its 2.7 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

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 in order to eliminate color casts and ensure cleaner, truer blacks when using the NiSi 100 x 100mm Nano IRND 2.7 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 100 x 100mm Nano IRND 2.7 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Q: 1. Can I combine this with a Nisi circular polarizer? which should be in front (which determines size i need)?

A: Yes, you can combine with NiSi circular polarizer. The size of the filter will be the same as the ND filter. The circular polarizer should be in front, after the ND filter, circular polarizer is being rotated more often then ND so should have easier access without disturbing exposure. When stacking multiple filters with rotating elements consider having Rubberized Filter Wrench https://www.bhphotovideo.com/c/product/1407950-REG/sensei_48_55mm_rubberized_filter_wrench.html of appropriate size due to possible difficulty of separating the filters when taking of the lens.
