Product Overview

NiSi 46mm Natural Night Filter (Light Pollution Filter)

The NiSi 46mm 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 46mm 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 46mm 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 46mm Natural Night Filter improve nighttime photography?

The NiSi 46mm Natural Night Filter enhances nighttime photography by specifically targeting and blocking unwanted yellow light emitted from common urban light sources, such as sodium-vapor and mercury-vapor lamps. This reduction in yellow light helps to improve the overall contrast and clarity of the night sky, making stars and other celestial objects more visible. By using this filter, photographers can achieve images with better colour fidelity and reduced glare, allowing for a more accurate representation of the night sky.

Can this filter be used with both film and digital cameras?

Yes, the NiSi 46mm Natural Night Filter is versatile and can be used with both film and digital cameras. For film cameras, it is best used with daylight film, while for digital cameras, photographers should select the daylight white balance setting. This flexibility makes the filter an excellent choice for various types of night photography, regardless of the camera system used.

What types of light sources does the filter specifically target?

The filter is designed to target and reduce the impact of light pollution from specific sources, primarily sodium-vapor lamps, mercury-vapor lamps, and low Color Rendering Index LEDs. These types of lighting are commonly found in urban areas and contribute to skyglow, making it difficult to capture clear images of the night sky. By blocking the dominant wavelengths from these sources, the filter enhances the visibility of astronomical features.

What is the significance of the nano coating on the filter?

The nano coating on the NiSi 46mm Natural Night Filter serves multiple purposes. It improves the beading effect when the filter comes into contact with water or oil, making it easier to clean and maintain. This feature is particularly beneficial for photographers who may be shooting in damp or humid conditions, as it helps to keep the filter clear of smudges and water spots, thus preserving image quality.

What should I consider when using this filter in urban environments?

When using the NiSi 46mm Natural Night Filter in urban environments, it's important to be mindful of the types of artificial lighting present. The filter is most effective in areas with significant light pollution, such as city centres or commercial districts. Additionally, while the filter reduces glare and enhances contrast, photographers should also consider their exposure settings, as the filter can reduce exposure by 0.6 to 1.5 stops. Adjusting your camera settings accordingly will help you achieve the best results.

How do I ensure compatibility with my camera setup?

To ensure compatibility with your camera setup, first check the diameter of your lens to confirm that it is 46mm, as this is the size of the filter. If your lens has a different diameter, you may need a step-up or step-down ring to fit the filter properly. Additionally, verify that your camera can be set to daylight white balance if you are using a digital camera, or make sure you are using daylight film for film cameras to maximise the effectiveness of the filter.
