Traditional animation

This animation called cel animation, the frames of a traditionally animated movie are hand-drawn. The drawings are traced or copied onto transparent acetate sheets called cels, which are then located over a painted background and photographed one by one on a rostrum camera. Nowadays, the use of cels (and cameras) is mostly obsolete, since the drawings are scanned into computers, and digitally transferred directly to 35 mm film. The "look" of traditional cel animation is still preserved, and the character animator's work has remained essentially the same over the past 70 years. Because of the digital influence over modern cel
animation, it is also known as tradigital animation.
Examples: The Lion King, Spirited Away, Les Triplettes de Belleville
Full animation
The most common style in animation, known for its realistic and often very detailed art.
Examples: All Disney feature length animated films, The Secret of NIMH, The Iron Giant
Limited animation
A cheaper process of creating animated cartoons that does not follow a "realistic" approach.
Examples: The Flintstones, Yellow Submarine Rubber hose
The characters are usually cartoony, and the animators have a lot of artistic freedom as rubber hose animations don't have to follow the laws of physics and anatomy in the same degree as the other main styles in animation.
Examples: Early Mickey Mouse cartoons, Ren and Stimpy, Popeye
Rotoscoping
A technique where animators trace live action movement, frame by frame, for use in animated films.
Examples: Gulliver's Travels, American Pop
