Hand drawn animation is a filmmaking technique where an artist draws each frame of a movie by hand, which are then compiled together to appear as seamless movement. Early examples from the 1930s used basic colors and had poor sound quality, while hand drawn films from the 1990s like Beauty and the Beast had improved colors and clarity. Modern 21st century hand drawn movies like The Princess and the Frog benefit from advanced techniques, appearing with perfect quality, colors, and sound.
