Sam Qureshi proposes techniques for applying realistic makeup, foley sounds, and camera tricks to aid in the planning of a horror open text sequence (OTS). Specifically, the document shares YouTube links demonstrating zombie makeup, horror sound effects created from vegetables, and an over-the-shoulder camera technique to depict violence without actual harm. The goal is to use these cinematic techniques to enhance the realism of characters and intensify the horror experience for audiences through an improved mise-en-scene and believable sound design.
