The Cokin 58mm NUANCES Clearsky 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 sky glow, 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 Cokin 58mm NUANCES Clearsky Filter can improve the results of nighttime images by absorbing the yellow light from sodium-vapor lamps or mercury-vapor lamps, 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 filter is constructed from optical-quality neodymium glass for clarity as well as color fidelity. It features an aluminum alloy filter ring for durability while remaining lightweight.

Related Questions and Answers

Q: 1. I've purchased this but when I rotate it I see no difference in the image. I bought this to remove reflections from windows but they remain just as strong as when I don't have the filter on. Am I doing something wrong?

A: The light needs to be at least partially polarized for a polarizer like this to work. If you are looking straight at the window and trying to remove reflections from behind you will see the least effect. You can experiment by putting yourself and the reflection you want to remove at an angle to the glass and you should start seeing more of an effect. You should find it is quite sensitive to the angle of reflection.

Q: 2. Will these filters and hood fit the Canon EF 70-300mm f/4-5.6 IS USM Lens?

A: fit fine on mine (model 0345B002 )

Q: 3. Will the hood and filters fit on an Olympus OM-D E-M5 Mk II with a Zuiko 14-150mm F 4.0-5.6 II lens? Specifically, will the filters clear the convex curve of the lens?

A: Yes, the lens hood and 58mm filters in this kit will work on the M.Zuiko 14-150mm F 4.0-5.6 II lens while mounted on the Olympus OM-D E-M5 Mark II.

Q: 4. Which way do I unscrew it to take it off? I have one on there now but I cracked it while birding today. I can't unscrew it and not sure if the impact of it hitting rocks caused it to jam the threading. I'm so bummed but glad my lens didn't take any damage. Thank you in advance for any reply.

A: Counter clockwise to unscrew. Try not to put pressure on the sides where it would put pressure on the threads. You may want to get a set of filter wrenches; https://bhpho.to/32suVwN

Q: 5. Are these particular filters good for long exposure photography?

A: You could use these filters for long exposure photography, yes. These are general use filters, including a circular polarizer, and a neutral density filter, which would be the most practical of the three to use for long exposures.

Q: 6. Will this work with the Fuji lens hood? The cinebloom does not. Outside diameter too large

A: The Moment 52mm CineClear UV Protection Filter has 52mm front thread so it should not interfere with the use of a lens hood on most lenses.

Q: 7. Are these filters glass? Are the frames plastic or aluminum?

A: Aluminum

Q: 8. How many filters fit into the filter case?

A: All three filters fit into the case, however I keep the UV and the polarizing filters screwed on the lens.

Q: 9. Is the base magnetic hollow ring included? Is the magnetic cap included?

A: Th Freewell 82mm Magnetic Quick-Swap Circular Polarizer Filter includes the magnetic cap.

Q: 10. Does it enable the use of a lens cap?

A: The 7artisans Photoelectric 82mm MRC-UV Filter does not have front filter threads, so a lens cap cannot be used.
