The NiSi Explorer Collection 150x170mm graduated neutral density filters (GND) are made for adventures!
These filters feature a special B270 tempered glass that makes them twice as durable as other typical glass filters. And of course they do not affect the coloration of the image and also have IR coating and the same dirt, water and oil repellant Nano coating as NiSi’s regular filters.
NiSi Explorer Reverse Graduated Filter GND4 (0.6) / 2 Stops is used to even out differences in brightness between the sky and landscape. Reverse GNDs are similar to normal GNDs except that the darkest part is located along the center of the filter. They have a specific use for shooting motifs where the light is most intense near the horizon and gradually diminish towards the sky.
Most commonly, this would include landscapes with no elements protruding above the horizon, such as a seascape towards an open ocean.
The NiSi 150mm Explore filters are compatible with the NiSi 150mm filter system
Note: These filters have undergone a tempering and hardening process to make them much less prone to accidental damage. But this does not mean they are unbreakable. After a period of time, the hardening may also decline.
