Frequently Asked Questions

What is the primary purpose of the NiSi Reverse GND4 filter?

The NiSi Reverse GND4 (0.6) filter is designed to balance exposures in landscape photography, particularly during sunrises or sunsets, by darkening the brightest part of the sky near the horizon while preserving foreground detail.

What are the dimensions of this filter?

This NiSi Explorer filter measures 150x170mm, which is suitable for use with compatible 150mm filter holder systems.

How durable is the NiSi Reverse GND4 filter?

The filter is crafted from hardened glass, making it less prone to accidental damage and more durable for use in various outdoor conditions.

Does this filter work for all types of landscape photography?

As a reverse graduated neutral density filter, it is specifically optimized for scenes where the brightest part of the sky is concentrated near the horizon. For other lighting scenarios, different types of GND filters might be more suitable.

What does "GND4" signify for this filter?

"GND4" refers to a 0.6 optical density, which means it reduces the light entering the lens by 2 stops at its darkest point, with the graduation being 'reverse' for horizon-specific brightness.

Strengths & Trade-offs

👍 Pros

Constructed from hardened glass, making this filter less prone to accidental damage and enhancing its durability in the field.
The Reverse GND4 (0.6) gradient effectively darkens the sky with the strongest effect near the horizon, ideal for sunrise/sunset photography.
Measures 150x170mm, providing ample coverage for wide-angle lenses and allowing for precise positioning within a filter holder.
Being an Explorer Filter from NiSi suggests a focus on robust design and performance for landscape photographers.
Helps in balancing exposures between a bright sky and a darker foreground, preserving details in both areas.

👎 Cons

The 150x170mm size means it requires a specific 150mm filter holder system, which is typically a separate and potentially expensive purchase.
The Reverse GND4 strength might not be sufficient or too strong for all lighting conditions, requiring other gradient filter strengths for versatility.
While made from hardened glass, it is not impervious to all damage and still requires careful handling.
The filter type is a reverse neutral density gradient, which is highly specialized for horizon-dominant scenes and less versatile than standard GNDs or solid ND filters.
No specific information about optical coatings (e.g., anti-reflective, hydrophobic) is provided, which can impact image quality and ease of cleaning.
