Final effect:
Before doing it, the effect I wanted was like the effect of a shot put hitting the wall hard and sinking in. However, the effect of hitting it in the east and west resulted in the effect of a stone character. The tutorial is as follows:
1. Materials: a photo of a rotten wall and a photo of a film
2. Create a new 500*350 canvas and insert a background image. Then adjust the brightness and hue as follows.
