How to correctly arrange the subject, companion, foreground, background, and blank space in the composition?

The general principle is: highlight the subject, enhance the atmosphere, harmonize the picture, and have appropriate proportions.

1. Subject: It is the main image used by the photographer to express the main idea and is the structural center of gravity of the picture. The subject in the photo can be an object or a group of objects.

That is, it can express a person, a thing, or even a storyline. Highlighting the subject is an important and primary task in photographic composition.

2. Accompanying body: It is the image used by the photographer to set off, set off, and assist the subject to express the content. The companion should play a good role in explaining, recommending and beautifying the subject. The subject can also be elaborated more deeply through the companion. However, the accompanying person can only play a role as a foil. When choosing and arranging the accompanying person, the photographer cannot take over the main role because what we want to emphasize is the main body, so except for the main body, everything else is secondary.

3. Background: refers to the scenery behind the subject that sets off the subject. The main function of the background is to explain the environment where the subject is located, highlight the subject's image, and enrich the subject's connotation. The background is the same as the ligand. It cannot be more eye-catching than the main body. It can only be used as a foil to highlight the supporting role of the main body. Otherwise, we will not be able to achieve the purpose of highlighting the main body.

4. Foreground: The foreground refers to the scenery in front of the subject. As a component of the environment, it plays a role in setting off the subject. Effective use of the foreground can enhance the sense of space in the picture and supplement the subject.

5. Blank: It is an important part of the photo screen. It is the other part besides the physical object that plays a foil role. Although it is not an entity, it can communicate with various objects on the screen and help the main photographer express emotions. Making good use of the blank space in the picture can highlight the subject while creating the artistic conception of the picture.
