The function of polarizer is to selectively let the light that vibrates in a certain direction pass through, and it is often used to eliminate or weaken the strong reflection on the surface of the object in photography, thus eliminating or reducing the light spot. When shooting jewelry, use a polarizer. By rotating the polarizer to the most suitable angle, the messy light spots on the surface of jewelry can be eliminated or alleviated, making the photos of jewelry clearer and more beautiful.

In order to eliminate or reduce the surface halo of jewelry, we should pay attention to the softness of light distribution and the illumination angle of main light source besides using polarizer. The light source is preferably a surface light source, avoiding a point light source. If lighting is used, you can add a soft mask to turn a point light source into a surface light source.
