What should I pay attention to when shooting a multi-person scene?

1. It can prevent the camera from being misplaced on the other side of the relationship line.

2. The actor's performance in the camera will be more natural, because he has someone to talk to instead of talking to the empty space. If the second actor can't be used when shooting the single shot of the first actor for some reason, then it is necessary to set a reference point for the actor on the side of the shading bucket.

Either a staff member stands there to replace the absent actor, or choose an object to achieve this goal. Some technicians like to put their fists next to the shading bucket as a reference point. The following figure shows this situation.

Actors who do not appear in the picture should be out of the camera's field of vision to ensure the correct layout of the camera position. Actor or body double B is located outside the lens, which provides a correct reference point for actress A and makes people feel that her attention is still focused on a certain object or character that has appeared in the lens before.
