How to grasp the structure of photos

Composition is the key to photography. Commonly used line compositions are: triangle, C, S, L, etc. The intersection of the "well" shape is the focus (also called interesting point) when people look at photos, so we should make full use of it. Generally speaking, photos should try to maintain a (visual) balance, such as the collocation of large and small elements (the big one is close to the midpoint and the small one is far from the center), the contrast of light and dark colors, the control of visible and invisible lines and so on. But if necessary, unbalanced composition will also bring full sense of movement and vitality.

Perspective (something that reflects three-dimensional space in two-dimensional space) is also often used for composition. Pay attention to the theme, story and appeal of photos. In addition, when reflecting the depth, the far viewpoint should stay in the picture (to avoid the divergence of visual guidance).
