NiSi 95mm Natural Night Filter (Light Pollution Filter)

The NiSi 95mm Natural Night Filter is specifically designed to combat light pollution, which can obscure the night sky and hinder the visibility of stars and other celestial objects. By blocking out the dominant yellow wavelengths produced by common urban light sources, such as sodium-vapor and mercury-vapor lamps, this filter improves contrast and clarity in your nighttime images. As a result, you'll capture more detail in the night sky and reduce the distracting glare from artificial lighting.

The NiSi Natural Night Filter is ideal for urban areas where light pollution is prevalent. It performs best when used with daylight film or a digital camera set to daylight white balance. Photographers often use this filter during astrophotography sessions, cityscapes at night, or any scenario where artificial light can obscure the night sky. It's beneficial for capturing the Milky Way, constellations, or city scenes that include dramatic lighting.

Yes, the NiSi 95mm Natural Night Filter is versatile and can be used with various camera systems, including both film and digital cameras. As long as your camera has a 95mm front filter thread, you can attach this filter directly. Additionally, it can be used in conjunction with other filters, allowing for creative combinations to achieve your desired photographic effect.

The nano coating on the NiSi Natural Night Filter enhances its surface properties, making it more resistant to water and oil. This results in an improved beading effect, which helps to prevent dirt and moisture from sticking to the filter. This feature not only makes cleaning the filter easier but also ensures that your images maintain clarity and sharpness by reducing the risk of smudges or streaks.

When cleaning the NiSi Natural Night Filter, it's essential to use a microfiber cloth or a soft lens tissue to avoid scratching the optical glass. You can also use a blower to remove any loose dust particles before wiping the surface. If there are smudges or stubborn marks, a lens cleaning solution specifically designed for optical glass can be applied. Always avoid using household cleaners or rough materials, as they can damage the filter's coating and glass.

While the NiSi 95mm Natural Night Filter is highly effective in urban environments with significant light pollution, its performance may vary in areas with minimal artificial light. In extremely dark locations, the filter might not be necessary, and using it could potentially result in a loss of some light, as it has a filter factor of 1.5 to 2.8x, which reduces exposure by 0.6 to 1.5 stops. Therefore, it is primarily recommended for use where light pollution is a concern.

The aluminum-alloy filter ring of the NiSi Natural Night Filter contributes to its overall durability while keeping the filter lightweight. This construction ensures that the filter can withstand regular use and travel without being prone to bending or breaking. Its lightweight nature also makes it easier to handle and reduces the overall weight of your camera setup, making it a practical choice for photographers on the move.
