Polarizer

Polarizers, also known as polarizers, are classified into two types, cpl and pl. Polarizers are accessory parts of the camera. The light itself is an electromagnetic wave. After reflection and diffusion, the vibration in a certain direction is weakened to become polarized light. Therefore, the reflection of the smooth surface and the diffuse light of the sky are polarized light, and these rays will affect the imaging. The clarity. The polarizer can choose to let the light oscillating in a certain direction pass, so the use of a polarizer can weaken the reflection of the surface of the object, can highlight the blue sky and white clouds and darken the sky. Polarizer is very useful in still-life photography and scenery photography.
