Why do TV dramas usually only shoot the upper body?

In TV series, the lens language is very important. Generally speaking, the upper body lens can better show the emotion and image of the characters. The following are several possible reasons:

1. Protruding expression and action: The upper body has elements such as head, arms and upper body, which can effectively express the emotional state and action characteristics of the characters, such as showing the smiling or angry expression of the characters and showing the movements of the arms.

2. Simplify the background: The size of the upper body is relatively small, which can reduce the number of photographic equipment and environmental settings needed for shooting and facilitate the production of TV dramas.

3. Reduce the space: Due to the limited size of the TV screen, the lens of the upper body can narrow the distance between the person and the shooting environment. This makes the framing range easier to control and adjust.

4. Highlight the role: In TV series, the role image is very important. The lens of the upper body can highlight the characters, which is convenient for the audience to understand and remember. This can help the characters to be more vivid and attractive, thus better serving the plot.

For these reasons, TV producers usually prefer to shoot with the upper body lens. Of course, this does not mean that there is no full-length lens at all, but sometimes full-length lenses are used to express certain scenes and emotions.
