Circular Polarizing Filter Features: A polarizing filter, used for photography, is colorless and does not affect the color balance, but filters out light with a certain polarization direction. This reduces oblique reflections from non-metallic surfaces, can darken the sky in color photography (in monochrome photography, color filters are more effective), and can saturate the image more by eliminating unwanted reflections. The main function of the circular polarizing filter (CPL filter) is to eliminate the scattered light in the air, as well as the reflected light from metal, glass, and liquid. It only allows parallel light through the lens, so that the camera can get a better picture such as blue sky, white clouds, clean water, and so on. When you rotate the CPL filter in its mount, the effects will appear immediately. Makes a blue sky bluer Enhances clouds Eliminates reflections Optical glass Black aluminum filter ring
