This document discusses common elements of horror genre films including camera techniques, mis-en-scene elements, editing styles, and sound design. It notes that horror films often use casual costumes for victims, dim lighting, the colors red, black and white symbolically, makeup to indicate distress, and isolated settings. Both diegetic and nondiegetic sounds are used to set an unsettling atmosphere. Effective elements that create fear include relatable victims and use of infrasound to induce anxiety without awareness. Overdramatic acting and reliance on dim lighting were critiqued as less effective techniques.
