NiSi Explorer 100x100mm IRND 64 6-Stops Square ND Filter

NiSi Explorer Collection 100x100 mm Neutral Density Filters

The NiSi Explorer Collection 100x100 mm Neutral Density (ND) filters are designed for adventurous photography. These ND filters are crafted from special B270 tempered glass, making them twice as durable as typical glass filters. They maintain true color fidelity without affecting image coloration and feature an infrared (IR) coating along with NiSi's proprietary Nano coating that repels dirt, water, and oil.

These 100x100 mm Explorer filters are compatible with the NiSi 100 mm filter system and can be used on lenses with filter thread sizes ranging from 49 mm to 95 mm.

Note: The filters undergo a tempering and hardening process to reduce susceptibility to accidental damage. However, they are not unbreakable, and the hardening effect may diminish over time.

How to Choose an ND Filter

Neutral Density filters reduce the amount of light entering the lens, enabling longer exposures and/or wider apertures to create effects such as motion blur or shallow depth of field.

• ND8 / 3 stops: Commonly used for photographing waterfalls and water flow with shutter speeds between 0.5 and 2 seconds.
• ND64 / 6 stops: Ideal during the "golden hour" (shortly after sunrise or before sunset) to achieve exposures of 1 to 2 minutes, producing smooth water or cloud effects. Also suitable for capturing dynamic water textures before the golden hour.
• ND1000 / 10 stops: Suitable for daytime use when bright ambient light requires significant light reduction. During the golden hour, it can extend exposures up to 5 minutes with appropriate settings.
