The NiSi Square Explorer 100x150mm Medium IR GND8 (0.9) reduces light by 3 stops to help you balance bright skies with darker landscapes. Designed for outdoor use, this graduated neutral density filter suits active photographers who need durable glass and reliable performance in varied conditions.
This graduated filter places a dark gray tone on the upper half while keeping the lower half clear. The 3-stop reduction in the dark area brings skies and bright highlights closer in exposure to foregrounds, which increases color saturation and makes cloud detail more pronounced. The medium-fast transition gives a balance between subtle and defined horizon blending, making the filter versatile for many landscape scenes.
The medium-fast transition is particularly suitable when the horizon is interrupted by natural elements such as hills and trees, or when shooting a sunrise or sunset over the sea. In short, it serves as a practical all-round graduated filter for landscape photographers who need a reliable way to control dynamic range without introducing color shifts.

The Nano coating helps repel dirt, water and oil, which makes routine cleaning and maintenance easier. Keep in mind that the glass has been tempered and hardened to resist accidental damage, but it is not indestructible. Over long periods the hardening treatment may diminish, so handle and store the filter with care to prolong its service life.
Question: What does "medium-fast transition" mean for composition?
Answer: A medium-fast transition places a defined but not abrupt boundary between dark and clear areas, making it easier to manage scenes where the horizon is broken by trees, hills or other elements without creating a hard line across the image.
Question: Will this filter change my image colors?
Answer: No. The NiSi Explorer series is designed not to affect image coloration, so the filter balances exposure without introducing color casts.
Question: How does the IR coating help?
Answer: The IR coating reduces infrared contamination that can cause unwanted color shifts or reduced contrast, helping to preserve accurate color and detail in your photos.
Question: Which lenses and systems does this filter work with?
Answer: The filter is compatible with the NiSi 100mm filter system and can be used with lenses that have filter threads from 49 mm to 95 mm, making it adaptable to a wide range of setups.
Question: Is the filter durable enough for outdoor use?
Answer: Yes. The B270 tempered glass used in the Explorer series is made to be about twice as durable as typical glass filters and is hardened to resist accidental damage, which suits active outdoor photographers. However, it is not unbreakable and its hardening may decrease with time, so proper care is still recommended.
