Traditional animation is a technique where each frame of a film is hand-drawn or painted. Artists create a series of images, slightly changing each one to create the illusion of movement when played in sequence. This method was widely used in early animated films, such as those produced by Walt Disney. The process involves creating a storyboard, designing characters, and then drawing each frame on transparent sheets called cels. These cels are layered over painted backgrounds and photographed to produce the final animation. Traditional animation requires significant time and skill, making it a labor-intensive art form.
