What is the basic principle of photography?

Balance and symmetry are the basis of composition, and their main functions are to stabilize the picture. Balance and symmetry are not a concept, but they have inherent identity and stability. The sense of stability is a visual habit and aesthetic concept formed by human beings in their long-term observation of nature. Therefore, all plastic arts that conform to this aesthetic concept can produce aesthetic feeling, while those that violate this principle will look uncomfortable. Equilibrium and symmetry are not average, but a logical proportional relationship. Although the average value is stable, it lacks change. Without change, there is no aesthetic feeling, so the most taboo of composition is that the picture is evenly distributed. Symmetry has a strong sense of stability, and symmetry can make the picture feel solemn, solemn and harmonious.

2. About comparison

Clever contrast can not only enhance the artistic appeal, but also clearly reflect and sublimate the theme. Comparative composition is to highlight the theme and strengthen the theme. There are various contrasts and ever-changing, but they are similar. We can draw the following conclusions:

The first is the comparison of modeling. Such as: big and small, tall and short, old and young, fat and thin, thick and thin.

The second is the contrast of colors. Such as: deep and shallow, cold and warm, bright and dark, black and white.

The third is the contrast between ash and ash. Such as: deep and shallow, bright and dark, etc.

3. About opinions

Viewpoint composition is to attract the audience's attention to the center of the picture. Viewpoint is the name of perspective, also called vanishing point. To make a clear point, we have to start from three lines: the apparent horizon, the horizon and the horizontal line.

The visual horizon is a line parallel to the eyes. We stand anywhere and look into the distance. There is a clear line where heaven and earth meet or where water and sky meet. This line is just parallel to the eyes. This is the obvious horizon. This line varies with the height of the eyes. The higher a person stands, the farther he can see, but you broaden his horizons by 300 miles.
