Interpretation of photographic lines

Formal statements in photographic works.

For example,

1. You shoot the horizon (sea level), put "between heaven and earth" in the middle of the photo, divide the whole picture in half, and draw a main line in the middle of the picture. Then, some people use this main line to distribute pictures with Sanqi, resulting in different picture effects.

2。 Shoot the pyramid, and then the triangle of the pyramid forms a line on the screen. Shooting this pyramid from different angles will produce different lines to outline the picture.

The important thing is, is the outline of this line good? In other words, is it nice? There is no standard, as long as people who look at this photo like it.
