(O/S) – The camera looks over a near person's shoulder (shoulder and back of head included in shot) at another person. Often this is used in interviews, the interviewer near and the interviewee facing back.
Commonly used in conversations between two actors. This shot is from the vantage point of the speaker. We can see the individual who is talking while seeing the listener from behind and over his or her shoulder.
