What is the structure of photography?

I will introduce you to some basic methods to prioritize and highlight the main portrait photos. Of course, it goes without saying that the characters are the main body and the beautiful background is also the foil. However, some people tend to look at the characters very small in photography (the main reason is that people run to the front of the scene and stay away from the camera, which is a common problem of most people's photography), but the scene is very large and there is no distinction between the foreground and the background, which means that the photo loses its structural center. For landscape films that are less prone to "subject", if the picture structure is not loose, we should choose an object as the fulcrum of the structure, such as a small bridge and a pavilion as the center of the structure, so that we can contact and take care of the scenery before and after. The "subject" in the scenery film is not necessarily more important than other scenery in content, but its role in the structural center is very obvious. Simple background and complex background of subtraction composition will bring interference to the subject, and even damage an excellent photo. The background should be handled concisely. Both painting and photography need composition, but the means of expression are different. The difference is that painting is composed by addition and photography is composed by subtraction. That is to say, painting composition always adds some scenery to the picture, and photography composition always tries every means to subtract those unnecessary scenery and the unnecessary scenery in the background, which hinders the main body from protruding, so as to achieve the simplicity and exquisiteness of the picture. Greed is the source of failure, and simplification is the mother of success. In the viewfinder of the camera used by the golden section wolf, there is a display format in which two straight lines form a "well" in the horizontal and vertical directions, which divides the picture into nine equal parts. At first, Lao Lang didn't know what it meant. Later, I learned composition, only to know that it is for the convenience of composition design: if the picture is divided into "nine squares", then the four intersections in the middle are the best places to arrange the main body. The positions of these four points are close to the golden section point 1:0.6 18, so it is easy to obtain better visual effects. Because people look at objects with their eyes, the middle position is the weakest visual area, so most photographers will not use middle composition when dealing with lines such as horizon and sea level, and focus will generally avoid the middle position. Besides the four points, there are two important "lines"-diagonal lines. There are many visual feelings, such as convergence and radiation, which are related to the diagonal hidden in the picture, so composition along the diagonal is also a very important composition method. A truly professional booth or studio will use a plain background to highlight the main body and avoid the "growth" of branches, telephone poles and other sundries from the characters. Outdoor photography also follows the principle of "plain and clean" background. Leave blank to enhance the sense of movement. To make the subject eye-catching and have visual impact, it is necessary to leave a certain gap around, which can be said to be a law of all plastic arts. The general rule of blank space is: the portrait on the side should leave some blank space facing the direction; For moving objects (such as people or cars), leave more white space in front of the direction of travel. Of course, this is just a general rule, so we should use the blank flexibly. If pedestrians emphasize the turban or dress fluttering behind and the smoke rising behind Mercedes-Benz cars, more space can be left behind than in front, because the center of gravity has changed. If the person who resists the edge of the picture is looking back, the blank behind will have meaning and the picture will not be embarrassed.
