A circular polarizer filter helps reduce reflections and look at the light that has become polarized due to the reflection of a non -metallic surface. Sun light becomes naturally partially polarized due to reflection on electrons in air molecules, causing the diffusion of light in what appears as mist. A polarizing filter arranges and filters, this directional polarized light perpendicular to the reflected light, allowing the absorption of a large part of this light. This results in a significant reduction in reflections and reflections from non -metallic surfaces and an increase in saturation of the sky, foliage, and allows the camera to capture what is below the surface of the shallow water.
