Product Overview

NiSi 55mm Natural Night Filter (Light Pollution Filter)

The NiSi 55mm Natural Night Filter is designed to reduce the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources. This effect can be obtained when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected.

Light pollution occurs in areas of the night sky that are above or near concentrated and intense sources of artificial light such as cities. These light sources can include exterior and interior lamps for commercial or residential buildings, brightly lit advertisements such as billboards, streetlamps, as well as sports and entertainment venues. Together, they can result in a type of light pollution known as skyglow, where individual stars, the Milky Way, and other astronomical features in the night sky are obscured. Additionally, artificial lights clustered together can become difficult to individually discern. Light pollution from these "cluttered" sources can become a source of distraction within an image and can resemble overexposed areas of glare.

When used, the NiSi 55mm Natural Night Filter can improve the results of nighttime images by blocking the yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LEDs, common light sources within urban areas. By preventing the dominant wavelengths of light associated with the color of those lamps from being recorded, the visibility of astronomical objects is enhanced, and artificial light sources are more clearly defined with less glare and improved contrast.

This NiSi 55mm Natural Night Filter is constructed from optical glass for clarity as well as color fidelity. Each glass surface includes one layer of nano coating. The nano coating associated with this filter results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.

FAQs

How does the NiSi 55mm Natural Night Filter improve night photography?

The NiSi 55mm Natural Night Filter enhances night photography by effectively reducing light pollution, particularly from common urban light sources like sodium-vapor and mercury-vapor lamps. By blocking the yellow hues emitted from these lights, the filter improves the visibility of stars, the Milky Way, and other celestial objects, allowing for clearer and more vibrant night sky images without the distraction of glare from artificial lighting.

Can the NiSi 55mm Natural Night Filter be used with digital cameras?

Yes, the NiSi 55mm Natural Night Filter is suitable for use with digital cameras. It is designed to work effectively when the camera is set to daylight white balance, ensuring that the colours captured are true to life while minimizing the adverse effects of light pollution. This makes it an excellent choice for astrophotography and urban night scenes.

What types of lighting does this filter target?

The filter specifically targets the yellow light emitted by sodium-vapor lamps, mercury-vapor lamps, and low Color Rendering Index LEDs, which are commonly found in urban environments. By filtering out these wavelengths, the NiSi 55mm Natural Night Filter helps to enhance contrast and clarity in both night sky photography and images featuring artificial lights.

Is the NiSi 55mm Natural Night Filter compatible with other filters?

Yes, the NiSi 55mm Natural Night Filter features 55mm front filter threads, allowing it to be easily stacked with other filters. This flexibility enables photographers to combine multiple filters to achieve desired effects, such as polarisation or neutral density, while still benefiting from the light pollution reduction capabilities of the Natural Night Filter.

What materials are used in the construction of this filter?

The NiSi 55mm Natural Night Filter is constructed from high-quality optical glass, ensuring clarity and colour fidelity in your images. Each glass surface is treated with a nano coating that enhances the filter's resistance to water and oil, making it easier to clean and maintain. The filter also features a lightweight aluminum-alloy ring that adds to its durability without compromising portability.

How does the filter's light reduction factor affect exposure?

The NiSi 55mm Natural Night Filter has a filter factor ranging from 1.5 to 2.8x, which translates to a reduction in exposure of approximately 0.6 to 1.5 stops. This means that photographers may need to adjust their exposure settings accordingly, either by increasing the ISO, opening the aperture, or extending the shutter speed to achieve the desired exposure level while using the filter.
