A polarizing filter is a type of optical filter that selectively absorbs light waves based on their polarization. This allows photographers to reduce reflections and glare, and to enhance the contrast of colors in their images.
Polarizing filters are an essential tool for any photographer who wants to improve the quality of their images. They can be used to reduce reflections from water, glass, and other non-metallic surfaces. They can also be used to enhance the contrast of colors in the sky, foliage, and other natural scenes.
