SHOT REVERSE SHOT

“Two or more shots edited together that alternate characters, typically in a conversation situation. In continuity editing, characters in one framing usually look left, in the other framing, right. Over-the-shoulder framings are common in shot/reverse-shot editing. Shot / reverse shots are one of the most firmly established conventions in cinema, and they are usually linked through the equally persuasive eyeline matches. ”
