Why do many people like to take pictures at a 45 angle? People shot from this angle really seem to look better and look more three-dimensional. Why?

Generally speaking, just don't shoot directly or completely sideways, the angle is in the middle. 1, front light, because the depth and outline are expressed through the interaction of light and shadow, so the front light creates a two-dimensional sense of plane, which is usually called "plane light"; 2, 45 degrees side light, he can produce a good light and shadow interaction, the proportion is balanced. The rich colors in form reflect a three-dimensional effect, and the surface structure is skillfully displayed. So it is also called "natural light"; 3.90-degree side light, used to emphasize dramatic light with strong contrast between light and dark. The side of the subject facing the light is bathed in strong light, and the side facing the backlight is buried in the dark, and the surface structure is prominent. Also known as "structured light". Therefore, it may be boring to shoot with the front light, and the 45-degree side light will look natural and beautiful. If you use 90-degree side light, you can imagine such a scene in the movie, an insidious old man, with one face in the strong light and the other face in the dark shadow, skillfully portrays the characters vividly with light.
