The process in animation 2d

Each shot in a 2D animation involves multiple single drawings of characters and some computer programs such as Anime Studio can create characters, which can be posed at different key frames, and the computer moves the character between those frames. To explain the concept, think of a still camera that can take many photographs in fast succession.. Each photograph should shot in individual drawing in an animation.

A shot may contain only one drawing but usually sometimes contain about ten to twenty drawings. These drawings are divided into keys and in-betweens. Keys are important drawings that convey the extremes of the character's movement-the first drawing is almost always a key while in-betweens or twins are the remaining, less important drawings in the shot.
Typically, each drawing begins with a sketch, in pencil, of the characters. This drawing is then cleaned up in ink, though this is not always done; Disney went through a period in which this step was skipped, as is most clearly visible. Skipping the inking step was thought to make the animation look more vibrant and alive, but critics and audiences didn't like the look. This is the point at which computers often step in. Some companies’ hand-ink each drawing, writing over the cleaned pencil lines with a pen. Others especially studios whose artists can draw very clean pencil lines will scan the pencils directly into the computer, then ink the drawing digitally.

The drawing is now considered a cell." Before computers, the drawing would now be photocopied onto a sheet of clear celluloid or acetate, then hand-painted. This created a "cell," which was placed on top of a background painting and filmed with the click of a film camera. Cells are still highly prized by collectors, though few true cells remain. Many of those on the market are reproductions.

Today, the digital cells are colored on a computer then saved on the computer as a single video file. In practice, the keys are usually drawn by a top animator, and these are then scanned. Then after doing our production stage then pre-product the film and it’s the last step.

Animation History from the first animation in the world till avatar


·        Definition of Animation
Animation it can be defined as kind of graphic can representing images that can show some motions of objects with some effects such as, sound, music and fast motion. The drawings are linked together and usually photographed by a camera.  The drawings have been slightly changed between individual frames with different motions.
Nowadays, animation conceder an effective tool for adverting and producing different ways to attract the target audience such as, 3d animation movies and Cartoons on television is one example of animation & Animation on computers
·        Early Animation
The first animation were found in Iran and it was 5 images sequence from a vase painted along the sides, showing phases of a goat leaping up to nip at a tree.
Other example, an ancient Egyptian mural, The Egyptian mural, approximately 4000 years old, shows wrestlers in action. The images looked like they blended together, and could actually move. In this way, the Egyptians discovered animation. On the other hand, the images they had draw represent stories with motions like this example

Zoetrope (1834)
The zoetrope is a device which creates the image of a moving picture. The earliest elementary zoetrope was created in China around 180 AD .Made from translucent
The modern zoetrope was produced in 1834 by William George Horner. The device is essentially a cylinder with vertical slits around the sides. Around the inside edge of the cylinder there are a series of pictures on the opposite side to the slits. As the cylinder is spun, the user then looks through the slits to view the illusion of motion. The zoetrope is still being used in animation courses to illustrate early concepts of animation.


Thaumatrope 1824

A thaumatrope was a simple toy used in the Victorian era. A thaumatrope is a small circular disk with two different pictures on each side. When the string is twirled quickly between the fingers, the two pictures appear to combine into a single image.

Phenakistoscope 1831


Flip book 1868
the first flip book was patented in 1868 by a John Barnes Linnet. Flip books were another development that brought us closer to modern animation. the Flip Book creates the illusion of motion. A set of sequential pictures flipped at a high speed creates this effect.

Animation Types
Animation is divided into three categories:
1-    Traditional Animation 
2-    Stop motion 
3-    CGI (computer generated imagery)

1-   Traditional Animation 
Traditional animation, the most popular type of animation, dates back to the early use of animation in films., or classical animation as it’s also called, originally consisted of hand-drawn images on each single frame, and very simple  background.
J. Stuart Blackton was the first person to make an animated film, which he called "Humorous phases of funny faces and he draw comical faces on a blackboard, one after the other, and film them.
In 1910, Emile Cohl came out with the first paper cutout animation. The development of celluloid, around 1913, made animation much easier to manage. Emile Cohl's Fantasmagorie 1908 was the first animated film that was made using traditional hand drawn animation. However, it was Walt Disney who took animation to an entirely new level altogether. In 1928, he became the first animator to add sound to his movie cartoons. Walt Disney achieved another

2-   Stop motion Animation 
In stop-motion animation, or stop action, an object is slightly moved then photographed by one frame at a time. Clay animation registered trademarked 1978 by Will Vinton and pixilation, both of them initially first used in 1908. The U.S. clay animated film, created by The Edison Manufacturing Company called  The Sculptor's Welsh Rarebit Dream 1908  is the first known clay animation In addition, the first person create special effect films is Georges Melies, was the first person to use animation with special effects. He was the one who gave the idea of stop motion animation
Go motion was first used in 1980 in Star Wars and was created in order to give a more realistic movement to the objects in the frame. Since each object, when shot using stop motion, is in crisp clear focus within each frame but  doesn’t represent realistic movement to the human eyes go motion provided the necessary effect to make a subject’s movement more life-like by creating motion blur. When shooting go motion, the subject, while being recorded, is moved. This creates motion blur. Although there are now multiple ways to make a subject move while it’s being recorded,

3-   CGI (computer generated imagery)
Most CGI created films are based on animal characters, monsters, machines or cartoon like humans. The first film done completely in CGI was Story The process of CGI animation is still very similar in that sense to traditional and still using many of the same principles. Now the principle become different CGI Animation compared to traditional animation is that drawing is replaced by 3D modeling, CGI animation is a combination of computer generated 2D and 3D imagery with animation techniques, and because of the advancements of computer technology and software, is now becoming the preferred style of animation. The difference between CGI and other types of animations is that everything is manipulated with a computer, one frame at a time. Each frame, after manipulation, must be rendered to give a good result and need fast computer.

Movies like ‘Star Wars’ depends on computer animation for many special effects. In 1995 they create a movie Toy Story’, produced by Walt Disney Productions and Pixar Animation Studios, the first full length film animated totally on computers. Since that time, animation and computer have gone hand by hand, creating new revolution and Superman 1978 was the first CGI film title

However, it wasn’t until recently, with the use of motion capture that CGI characters have become more realistic. Animation studios are now trying harder to develop many ways of creating realistic looking of humans’ animals, and other characters. These is some of the examples

1.    Final Fantasy 2001,
2.    Final Fantasy: Advent Children in 2005,
3.    Beowulf in 2007 and Resident Evil Degeneration in 2009
4.    Avatar 2009
