The difference between polarizer and polarizer

Different applications and different functions.

1, different uses: polarizer is mainly used to eliminate and weaken the strong reflection of non-metallic surface, thus eliminating or reducing light spots; Polarizers are mainly used for color and black-and-white photography to eliminate or weaken the strong reflection of nonmetallic surfaces.

2. Different functions: the color removal function of the polarizer is to selectively let the light vibrating in a certain direction pass through; The color removal function of polarizer is to filter out a lot of polarized light in diffuse reflection, thus weakening the light intensity in the sky, darkening the sky and increasing the contrast between blue sky and white clouds.
