About: Over the shoulder shot

In film or video, an over the shoulder shot (also over shoulder, OS, OTS, or third-person shot) is a shot of someone or something taken over the shoulder of another person. The back of the shoulder and head of this person is used to frame the image of whatever (or whomever) the camera is pointing toward. This type of shot is very common when two characters are having a discussion and will usually follow an establishing shot which helps the audience place the characters in their setting.
