Excuse me, how to adjust the color of the sky in such a landscape photo?

These are not the results of color matching. Judging from the color of the cloud, the color is very positive. If the blue channel is added separately, it will affect the balance of other colors to some extent.

Good photos are not taken by post-adjustment, but by innate accuracy. I don't object to the later revision, but I can't go too far. That's unnatural.

Finally, I will tell you a skill to shoot the blue sky! !

When you shoot the skylight, it is important to get accurate exposure, but if you want to make the sky bluer, you must shoot the sky along the light to make it bluer. The angle between the lens shooting direction and the sun must be greater than 100 degrees, and the genius may be blue.
