NiSi Light Pollution Filter

NiSi Light Pollution Filter

In the realm of night photography, the battle against light pollution is an ongoing struggle for photographers seeking pristine, natural nightscapes. NiSi Filters has stepped into this arena with their groundbreaking solution โ€“ the NiSi Natural Night filter. In this comprehensive review, we'll explore the features, specifications, and real-world performance of this tool designed to combat the adverse effects of light pollution.

Understanding the Light Pollution Challenge

Light pollution poses a significant challenge for night photographers, whether they are within city limits or immersed in the serene beauty of nature. The orange color cast caused by artificial lights can detract from the visual appeal of images. NiSi Filters recognized this issue and introduced the Natural Night filter as a dedicated solution.

NiSi Natural Night Filter Overview

The Natural Night filter from NiSi is a testament to the company's commitment to innovation in the field of night photography. It is their first filter dedicated solely to the challenges posed by nightscapes and light pollution. At the time of writing, the filter is available for NiSi's 100x100mm holder systems, specifically the V5 or V5Pro. Although not yet tested on larger lenses, conversations with NiSi suggest a potential release of a 150mm version in the near future.

Compatibility and Lens Options

For testing purposes, the reviewer utilized the filter with a Nikkor 16-35mm f/4 and a Fujinon 23mm f/1.4. While the Natural Night filter may currently have limitations in terms of lens compatibility, discussions with NiSi indicate a proactive approach to address this concern with the potential release of a 150mm version.

How Does It Work?

The NiSi Natural Night filter is engineered to combat the detrimental impact of mercury vapor, sodium, and Low CRI (Color Rendering Index) streetlight wavelengths. These artificial lights often contribute to the undesirable yellow or orange glow associated with light pollution. The filter's objective is clear: to enhance the visibility of celestial bodies in the night sky while minimizing the impact of urban and artificial lighting.

Filter Construction and Variants

Launched in 2017, the Natural Night filter boasts a distinct design focused on blocking specific wavelengths associated with common sources of light pollution. Available in various sizes, including 180mm, 150mm, and 100mm square varieties, as well as 77mm and 82mm circular versions, NiSi offers versatility to accommodate different filter holders.

Optical Glass Quality and Coating

Crafted from high-quality, lens-grade optical glass, the filter features a double-sided multi-layer coating that is both waterproof and oil-resistant. This coating not only enhances durability by preventing smearing but also minimizes ghosting and flaring.

The Impact on Night Photography

Night photographers face the challenge of capturing captivating images while combatting the adverse effects of light pollution. The Natural Night filter aims to alleviate this challenge by selectively blocking wavelengths associated with common sources of light pollution. The reduction of mercury vapor, sodium, and Low CRI streetlight wavelengths contributes to a more natural and visually pleasing representation of the night sky.

User Experience and Quality Assurance

Drawing from the reviewer's extensive experience with NiSi filters, a consistent theme emerges โ€“ a commitment to quality. The reviewer notes the durability and high performance of NiSi filters even after a year of rigorous use. The Natural Night filter aligns with this standard, instilling confidence in its robust construction and resistance to breakage.

Nano Coating Technology

NiSi's Nano Coating technology takes center stage in the Natural Night filter. This multi-layer coating serves multiple purposes, including reducing reflections on the filter's surface, minimizing ghosting and flare, and facilitating easy cleaning. The protective layer ensures that water, dust, and oil can be wiped off without compromising the filter's integrity.

Spectrum Test and Reduction of Light Pollution

A critical aspect of the Natural Night filter is its ability to reduce light pollution effectively. The filter undergoes a spectrum test, revealing a sharp cut of the curve at approximately 580-600nm. This targeted reduction in specific wavelengths contributes to the restoration of the night sky's natural beauty, free from the intrusive hues of artificial lights.
