Traditional Ink and Paint Process:
Each cel involved in a frame of a sequence is laid on top of each other, with the background at the bottom of the stack. As the cel of one character can be seen underneath the cel of another, the transparent quality of the cel allows for each character or object in a frame to be animated on different cels, and the opaque background will be seen beneath all of the cels. In order to flatten any irregularities, a piece of glass is lowered onto the artwork and then by rostrum camera (a special animation camera), the composite image is photographed.
The camera is then used to create pans, zooms, and rotation on the including overlays as well as animated transparency and blur effects. Once all the layers including overlays and background are animated, they are composited and output directly to video.

Digital Ink and Paint Process:
The inked and painted sequences of images are then animated under virtual animation cameras, to create pans, zooms, and rotation on the including overlays as well as animated transparency and blur effects. Once all the layers including overlays and background are animated under the virtual camera, they are composited and then output directly to video or onto storage media for transfer onto films. All camera actions motions (complex pan, deep zoom tilt) etc. Since the invention of these types of computer systems animation has never had so much freedom of style.
