The filmmakers learned several important lessons when progressing from their preliminary editing task to their final film. For lighting, they gained an understanding of how lighting can be used to set mood and atmosphere, such as low-key lighting for a thriller genre. For sound design, they learned the importance of non-diegetic elements like music and foley effects to build tension and realism. Continuity of camera placement and adherence to techniques like the 180-degree rule and rule of thirds composition improved the flow and professionalism of the final film.
