What do you mean by ups and downs in photography?

If you're sure you mean photography, not video. Then this fluctuation should be the narrator's own understanding of photographic composition.

Fluctuation may refer to color change, line change, mood change, light change and sight guidance change.

I prefer what a friend said, the photo is telling a story. It's a wonderful moment to like photography recently. Representative figures of two kinds of wonderful moment theories: Bresson and Frank. So when shooting, don't shoot, just shoot. There are photographers in China who know this.

Simple ups and downs cannot constitute the elements of composition. It also needs harmony, theme, opportunity and angle. To be honest, I think the word ups and downs only describes a special scene of composition. For example, an oblique S-shaped combination.
