The 2 shots are a type of lens that consists of two people (body) frames. Subjects do not have to be adjacent to each other, there are two common shots. One is the foreground and the other is the background.
The classic two lenses are taken with a medium lens, from the head to the knee, or closer (the terms of the two lenses stand for "medium two lenses"), and letters are displayed. Face General changes include outlines of two persons, a silhouette of one person and 3/4 or completely facing the camera, two people watching the camera side by side, is it a contour? , 3/4 or full face, or two shots in the mirror?
"From 2 shots to the west", one character is 180 degrees from the other character and the other character sees them.
In "Full 2 shots", two characters are displayed from head to toe. "Two lens" is a main lens that shows that two people are using wider lenses, including the surrounding overview. "Close-up shot" is a close-up shot taken with a long shot, with two human heads in the frame. This frame is usually used to kiss two people or to take a picture at a moment with a dramatic tension.
For classical movies, long-time shooting is often used. There, several types of lenses are used without cutting. For example, if two people are talking to the camera with a middle lens and the foreground character is facing away from the camera, the lens will be an "overshoulder" or "OTS" lens. After that, if the character moves to the background character and both characters are outline, the shot becomes full 2 shots. As the camera approaches, the lens will again be inside twice.
But "one shot" has a different meaning. It is used to describe a film shot at once, usually a continuous shot without clipping.

Two shots present two characters in the same frame. This is a natural way of introducing two people and can be used to clarify relationships between each other. To convey different messages about the character, different variants of the two shots can be applied. For example, if the characters are next to each other, they may leave the impression that they are equally important in the scene.
