The document discusses three media techniques: the 180 degree rule, shot/reverse shot, and match on action.
The 180 degree rule establishes orientation by keeping characters on the same side of an imaginary axis between them. Breaking this axis can disorient viewers. Shot/reverse shot shows one character looking at another and then vice versa to depict a conversation. Match on action edits two shots together where an action begun in one is continued in the next, like raising a glass to the mouth, to preserve continuous motion.
