NiSi Square Filter Explorer 150X150mm IRND 1000 10Stops

NiSi Square Filter Explorer 150x150mm IRND 1000 – 10 Stops for extended daytime long exposures

The NiSi Explorer 150x150mm IRND 1000 is a neutral density filter designed to block 10 stops of light. It belongs to the NiSi Explorer series of hardened glass filters, created for outdoor and active photographers who need reliable light reduction for long exposures during bright conditions.

Key features and construction

The Explorer series uses hardened glass to reduce the risk of accidental breakage compared with standard glass filters. These filters include an IR coating and the same Nano coating used on NiSi’s regular filters. The Nano coating repels dirt, water and oil, and the IR coating addresses infrared issues without affecting image coloration.

Durability and handling

The Explorer collection is produced using a tempering and hardening process. This makes the glass much less prone to accidental damage and, for the models described in the original Explorer collection, uses B270 tempered glass that is reported to be twice as durable as other typical glass filters.

Note that tempered and hardened glass is not unbreakable. The hardening may also decline over time, so normal care and sensible handling remain important.

When to use an ND1000 / 10-stop filter

An ND1000 (10-stop) filter is suited for daytime use when ambient light is very bright and you need substantial light reduction. The NiSi Explorer ND1000 lets you extend shutter times significantly to capture motion blur or smooth water and clouds while maintaining desired exposure settings.

Examples from the Explorer guidance:

• ND8 / 3 stops: commonly used for waterfalls and water flow, producing motion blur at shutter speeds roughly between 0.5 and 2 seconds.
• ND64 / 6 stops: often used near sunrise or sunset (golden hour) to allow exposures around 1–2 minutes and to smooth water or clouds while preserving some texture.
• ND1000 / 10 stops: suitable for daytime when much more light blocking is required. During golden hour the ND1000 can also prolong exposures for up to about 5 minutes with the appropriate camera settings.

Compatibility note from the Explorer collection

The original NiSi Explorer collection included 100x100 mm neutral density filters that are compatible with the NiSi 100 mm filter system and were noted as usable on lenses with filter threads from 49 mm to 95 mm. This is part of the Explorer collection information provided for the 100x100 mm format.

FAQ

Question: What does the ND1000 / 10-stop rating mean in practice?
Answer: A 10-stop ND (ND1000) reduces incoming light significantly so you can use much longer shutter speeds in bright daylight. This helps you create motion blur in water or clouds and achieve very long exposures that would otherwise be impossible without heavy light reduction.

Question: Does the filter change the colors in my images?
Answer: The Explorer filters are designed not to affect image coloration and include an IR coating to manage infrared issues, preserving the natural color balance of your photos.

Question: How durable are these Explorer filters and are they unbreakable?
Answer: The Explorer series uses a tempering and hardening process and the collection references B270 tempered glass that is twice as durable as typical glass filters. However, they are not unbreakable. The hardening can decline over time, so treat the filter with care.

Question: What coatings does the filter have and how do they help?
Answer: The filter includes an IR coating and a Nano coating. The Nano coating repels dirt, water and oil, making the surface easier to keep clean while the IR coating helps control infrared light without altering image colors.
