This document discusses various film techniques including extreme close-up, close-up, medium shot, pan, high angle shot, tilt, diegetic sound, and non-diegetic sound. An extreme close-up focuses intensely on a character's facial expressions to convey their emotions. A close-up also shows emotion through the face. A medium shot provides context of the character's surroundings while still showing facial expressions. A pan or tilt can set the scene and track character movement. Diegetic sound is audible to characters while non-diegetic sound, like music, creates suspense but is not heard by characters.
