NiSi Variable ND Viewing Filter 1-6 StopsThe NiSi Cinema V-ND Variable Viewing Filter (1 to 6 Stops) is a variable viewing filter from 1 to 6 stops. When you\u2019re setting or focusing your lights it\u2019s helpful to be able to stand in the spot where you want the light to hit, and look up directly into it as it\u2019s being focused. NiSi have made an up to date version of the tool that uses a variable ND filter.
