As a photographer, I often encounter this situation: the photos I just took are not good-looking, and after a while I feel good-looking. What happened?

When you first shot, you saw the real thing. You compared it with the photo in your heart. The photo is not as real as the real thing, and it doesn't feel good. After a while, the real thing has disappeared in my mind, and the photo is really in front of me. There is no harm without comparison, so the photos are also quite good.
