High angle shots show those with power looking down, while low angle shots make characters seem larger and more threatening as they loom over others. Long shots establish settings, and extreme close ups focus on important props, gestures, or interactions. Medium shots show characters from the waist up, ideal for conversations. Close ups focus on heads and shoulders to convey emotions. Extreme long shots depict distant places or a character's point of view looking out over a scene, common in horror. Different shot types are used to manipulate perspective and focus audience attention in films.
