Animation drawing is a form of art that involves creating moving images through the use of drawings. It is a process that combines drawing, painting, and other traditional art techniques with the latest technology to create a sequence of images that appear to move when played back in rapid succession. CEL animation, also known as CEL-shading or hand-drawn animation, is a type of animation that uses cels, which are transparent sheets of celluloid, to create the illusion of movement. The cels are placed over a background and then drawn on with pencils, markers, or paint. The cels are then photographed one frame at a time and the resulting images are combined to create the illusion of movement.
