Product Overview

NiSi 67mm Natural Night Filter (Light Pollution Filter)

The NiSi 67mm 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 67mm 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 67mm 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 67mm Natural Night Filter improve night photography?

The NiSi 67mm Natural Night Filter enhances night photography by specifically reducing the impact of light pollution, which is prevalent in urban areas. By blocking the yellow light emitted from common artificial sources like sodium-vapor and mercury-vapor lamps, the filter improves contrast and clarity in your images. This allows for better visibility of celestial objects, such as stars and the Milky Way, that would otherwise be obscured by skyglow and glare from artificial lighting.

Is this filter suitable for both digital and film cameras?

Yes, the NiSi 67mm Natural Night Filter is designed to be compatible with both digital and film camera systems. For film cameras using daylight film, it can be used effectively to manage light pollution. For digital cameras, setting the white balance to daylight will optimise the filter's performance, ensuring that the colours in your night sky shots remain true to life while minimising the effects of artificial lighting.

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

The nano coating on the NiSi 67mm Natural Night Filter serves multiple purposes. It enhances clarity by reducing reflections and ghosting, which can occur in challenging lighting conditions. Additionally, the coating improves the filter's resistance to water and oil, making it easier to clean and maintain. This means that you can keep the filter in optimal condition, ensuring the best possible image quality during night photography.

Can I stack this filter with other filters?

Yes, the NiSi 67mm Natural Night Filter features 67mm front filter threads, allowing you to stack it with other filters. This flexibility enables photographers to combine different types of filters tailored to their specific needs, such as polarising filters or ND filters, to achieve unique effects or manage exposure levels while shooting at night.

What kind of results can I expect when using this filter?

When using the NiSi 67mm Natural Night Filter, you can expect to see enhanced visibility of stars and astronomical features in your images, with reduced glare from artificial lights. The filter effectively improves contrast, making celestial objects stand out more prominently against the night sky. This is particularly beneficial for astrophotography or any nighttime scene where artificial lighting may detract from the overall composition.

How does the filter factor of 1.5 to 2.8x affect my exposure settings?

The filter factor of 1.5 to 2.8x indicates that the NiSi 67mm Natural Night Filter reduces the amount of light entering the lens, which equates to a decrease in exposure by approximately 0.6 to 1.5 stops. This means that when using the filter, you may need to adjust your camera settings, either by lengthening the exposure time, increasing the ISO, or opening the aperture to properly expose your images in low-light conditions.

What materials are used in the construction of the filter?

The NiSi 67mm Natural Night Filter is constructed from high-quality optical glass, which provides excellent clarity and colour fidelity. The filter ring is made of durable yet lightweight aluminium alloy, ensuring the filter is robust enough for regular use while remaining easy to handle. This combination of materials helps to maintain the integrity of your images while providing a reliable tool for night photography.
