How to make the sky bluer?

Reducing exposure compensation and adding a polarizer in front of the lens can make the sky bluer.

Method 1: reduce exposure compensation:

Adjust the exposure compensation negative 1 to 3rd gear for debugging.

Principle: When taking style photos, the brightness of the sky is generally higher than the ground, and the camera will average the exposure value after automatic metering, which will lead to overexposure and whitening of the sky. By reducing the exposure compensation, the sky can be exposed normally and appear blue.

Method 2: Add a polarizer in front of the camera:

Adding a polarizer in front of the lens can filter polarized light.

Principle: Polarizer can selectively let the light that vibrates in a certain direction pass through, and it is often used to eliminate or weaken the strong reflection of non-metallic surface, thus eliminating or reducing the light spot. In scenery and landscape photography, it is often used to show the texture of objects with strong reflection, highlight the scenery behind the glass, darken the sky and show blue sky and white clouds.
