In each frame, the position of the cartoon characters changes very slightly from their positions in the preceding frame. When all of the frames are completed, they are placed in order from first to last and can be photographed to produce a cartoon. It typically takes 24 frames to make one second of animation. In the following example, try to pick out the individual frames. Animation by Lee Mishkin of VanArts, taken from the VanArts page In computer animation, the process of making individual frames is still used.
Computer animators draw out each individual frame on the computer.
However, since computers are used to help them do their work, they can create very realistic pictures that look more like a movie than a cartoon. Computer animators don't have to draw every frame in computer animation. In hand-drawn animation, the artist must draw every frame to get Daffy Duck to walk from the left side of the screen to the right side. Let's pretend that an artist must draw thirty frames to get Daffy Duck to walk across the screen. For example, he would draw frames numbered 1,3,5,7,9, etc.
