The document discusses technical skills learned from completing a preliminary task and final thriller production. It describes learning shot reverse shot editing to create tension, improving lighting to set atmosphere and imply meaning, and adding soundtracks and microphones to enhance emotion and pacing. Shots from the preliminary task show simple lighting that did not set mood, while the thriller used backlighting, spotlights, and scores to craft mystery, danger and suspense. Working from a brief helped narrow ideas and plan shoots efficiently to experiment and engage the audience from multiple angles.
