The HOYA STARSCAPE filter is designed for photography of night landscapes and reduces light pollution from artificial light that is common in cities. The HOYA STARSCAPE reduces light transmission in the region of the spectrum normally associated with light pollution from sodium and mercury vapor lamps common in most cities around the world. As a result, the filter provides a clearer image with natural colors and improved contrast in the night sky. The HOYA STARSCAPE filter is very useful in time-lapse photography. By reducing light pollution directly during the shooting process, the time required for post-processing is significantly reduced. The combination of HOYA STARSCAPE and SOFTON-A will allow the bright stars in the night sky to be highlighted even more, making the image more impressive and attractive.
