NiSi Filter IRND Long Exposure Kit 100mm

NiSi Filter IRND Long Exposure Kit 100mm – Three 100x100mm IR Neutral Density Filters for Extended Shutter Speeds

This NiSi Long Exposure Kit 100mm includes three 100x100mm IR neutral density (IRND) filters and a soft filter pouch. The kit gives you a range of light reduction options to extend shutter speeds, capture motion blur, and control exposure in high-contrast scenes.

What the kit contains

• Three 100 x 100 mm IR Neutral Density filters:
  • ND8 — 3 Stop
  • ND64 — 6 Stop
  • ND1000 — 10 Stop
• NiSi soft filter pouch that holds up to 4 × 100 x 100 mm filters or 4 circular filters up to 95 mm
• Cleaning cloth
• Four replacement foam gaskets

Practical use and exposure guidance

Neutral density filters uniformly reduce the amount of light entering the lens. As a result, you can use larger apertures and slower shutter speeds to create motion blur and capture movement in water, clouds or other subjects.

Specifically:

• The ND8 (3 Stop) is commonly used for waterfalls and flowing water. It enables shutter speeds in the range of about 0.5 to 2 seconds to create smooth but detailed water motion.
• The ND64 (6 Stop) works well around sunset hour. It allows much longer exposures — typically around 1 to 2 minutes — for very smooth water or cloud movement. You can also use 6-stop density to capture dynamic water while retaining some texture before sunset.
• The ND1000 (10 Stop) provides strong light reduction for daytime shooting outside sunset hour. With the appropriate camera settings, it can prolong exposures for up to 5 minutes during sunset hour when you need maximum light blocking.

How ND filters help your images

By limiting incoming light, ND filters let you control motion blur, select shallower depth of field under bright conditions, and prevent blown highlights when the contrast between highlights and shadows is too high. Use these filters to achieve creative long exposures and better-balanced exposures in high-contrast scenes.

IRND features: color neutrality and glass construction

NiSi IRND filters are made from high-quality optical glass (not resin) and feature a nano coating. These properties help preserve fine image detail and keep colors true to life.

Importantly, cameras become more sensitive to infrared light when you use neutral density filters. This sensitivity can cause an unwanted red color cast in images when shooting at small apertures. NiSi IRND filters include an infrared protection coating layer to block that infrared light and restore natural, true-to-life color.

Storage and accessories

The included soft filter pouch holds up to four 100 x 100 mm square filters. It also accepts up to four circular filters up to 95 mm in diameter. In addition to filter storage, the pouch contains a cleaning cloth and four replacement foam gaskets to help maintain the filter holder and filter fit.

FAQ

Question: Which filters are included in the NiSi Long Exposure Kit 100mm?

Answer: The kit includes three 100 x 100 mm IRND filters: ND8 (3 Stop), ND64 (6 Stop) and ND1000 (10 Stop), plus a soft filter pouch, cleaning cloth and four replacement foam gaskets.

Question: Will these filters change my image colors?

Answer: NiSi IRND filters are designed to be color neutral. They are made from optical glass with a nano coating and include an infrared protection layer to prevent the infrared-induced red cast, so they maintain true-to-life color.

Question: When should I use each ND filter?

Answer: Use the ND8 (3 Stop) for moderate slow-shutter effects like waterfalls (around 0.5–2 seconds). Choose the ND64 (6 Stop) for longer exposures near sunset (often 1–2 minutes) to smooth water and clouds. Use the ND1000 (10 Stop) for heavy light reduction during daytime or to extend exposures up to several minutes with the right settings.

Question: How many filters can the pouch hold and can it fit circular filters?

Answer: The included soft pouch holds up to four 100 x 100 mm square filters, and it can also accommodate up to four circular filters up to 95 mm in size.

Question: Are these filters made from glass or resin?

Answer: These NiSi IRND filters are made from high-quality optical glass, not resin, and they include nano coating for detail preservation and an infrared protection layer for accurate color rendition.
