Whenever you need to look directly at strong sources of light, the Cinema 10-Stop Viewing Filter with Neck Strap from NiSi enables you to do so without hurting your eyes. Similar to an ND filter, this viewing filter reduces the amount of visible light reaching your eyes to help you determine the position of light fixtures or the sun. The filter's Nano coating stops UV and IR light for additional protection.
The viewing filter is made of aviation-grade aluminum, with easy-to-replace, removable glass. A silicone eyecup on the rear of the filter prevents light leaks. For convenience, the filter comes outfitted with a neck strap so you can keep it handy during your work on set.
