Production Design refers to the creation and realization of the overall visual concept, including set design, costumes, lighting, and sound for a film or stage production. It involves working closely with the director, cinematographer, and other members of the creative team to create an environment that supports the story being told on screen or on stage. The goal is to establish a cohesive visual style that enhances the narrative and helps bring it to life for the audience. Production design can also involve creating concept art and models to help communicate the vision to the rest of the crew, as well as overseeing the construction and execution of the final product on set or in the theatre.
