[A filter that cuts light pollution and reveals the true colors of the night sky] "Starry Night" is a filter for starry and nightscape photography that effectively cuts light pollution from lights such as sodium lamps and mercury lamps. [Cuts out only light in specific wavelength ranges] It cuts out only the wavelength ranges of light commonly used in street lights, such as 589nm (sodium lamps) and 435nm/546nm/577nm (mercury lamps), allowing you to express the original colors of the night sky. [Can be used without lens restrictions] Starry Night has no restrictions on the focal length of the lens that can be used, and color shift does not occur even with wide-angle lenses, making it suitable for starry sky photography. It is also effective for time-lapse photography, which is difficult to post-process. [Can be used with auto white balance] Starry Night is not a color-adjusting filter, so you can leave the white balance on auto. You can manually adjust the color temperature to your liking.
