What is celluloid film? Common stuff that has that kind of stuff on it, what is cellophane?

If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP).

In the training institutions in the field of "board painting, CG painting, impasto", [Wang's Education] is the leader in China, and it has not joined the branches, and it is a chain campus directly operated by the headquarters. Different from many other large institutions of the same type: each campus of Wang's Education is physically face-to-face, the teachers are hand-in-hand, and there are special class teachers from morning to night, and the liver-bursting learning mode will improve quickly, especially suitable for students with poor foundation.

Celluloid refers to the old brand name used in plastics, and it is the earliest artificially manufactured plastic.

History: In 19th-century Europe, playing billiards was a very popular pastime for high society. In the early days, billiards were made of ivory, and more than 20,000 elephants were killed every year to obtain ivory, and due to the scarcity of ivory, production was very limited, so a reward of $10,000 was offered for alternative materials to make billiard balls.

In 1869, someone coheated a mixture of nitrocellulose, camphor and ethanol under high pressure, and then hardened it under atmospheric pressure to make a cheap billiards, which won this prize, so billiards as a sport began to gradually become popular in society. This material made from cellulose is called "celluloid". "Celluloid" became the first artificially manufactured plastic.

Celluloid refers to the old brand name used for plastics, and it is the earliest synthetic plastic produced commercially. It is a substance formed by nitrocotton and camphor after enhancing its plasticity. Colorless and transparent, it can be used to make film films and imitation tortoiseshell, ivory, etc.

Celluloid tends to be thinner and lighter than bakelite, and when heated to higher temperatures, it becomes brittle and can crack. Even some celluloid flakes are flammable and although more brittle than bakelite, it can still be bent or twisted. Under hot water, most celluloids have a taste like vinegar or old camphor.

Celluloid jewelry can be damaged by moisture, extreme temperatures, or chemicals. Celluloid stored in a confined environment for a long time can also be very sluggish and even crack.

Celluloid is made from nitrocellulose and raw materials such as alcohol and camphor, and it was after the advent of celluloid film that the film was developed. However, this kind of film can easily catch fire, so at that time, firefighters had to be on duty in the screening room to show movies.

Previously, billiards were made of ivory, which could only be obtained from dead elephants, which naturally created problems. In the early 60s of the 19th century, there were.

A $10,000 prize was offered to solicit the best substitute for ivory, which must meet the requirements for billiards, such as hardness, elasticity, resistance to heat, moisture and no texture. Many people are eager to try it, and American inventor Hayt is one of them. By 1869, Heyat had won the prize by making cheap billiards from the substance he called celluloid.

It was later learned that celluloid is used in a variety of ways and goes far beyond the pool table. It is capable of molding at the boiling point temperature of water; It can be cut, drilled, or sawn at lower temperatures; It can be a hard clump or made into a soft sheet (it can be used to make shirt collars, children's toys, etc.). Thinner and tougher flakes can be used as:

The base of the colloidal silver compound, so that it became the first practical photographic negative.

Now its most common use is to make table tennis, other uses are in the chemical industry, aerospace, machinery, printing and dyeing, etc.

A mixture of nitrocellulose, camphor and ethanol is coheated under high pressure to make it to the model, and then hardened under atmospheric pressure. The first synthetic plastic developed by Hayt is a tough material celluloid, which has great tensile strength, water resistance, oil resistance, acid resistance, and can produce products of various colors at low cost, opening the way for the development of the modern plastics industry.

At the beginning of the last century, celluloid had many applications, and could be molded or calendered into products of any shape, such as making combs, toothbrushes, collars, film toys, car windshields, piano keys and photographic films, handicrafts and other consumer goods, in 1890, American photography popularized and promoted the development of film production technology and the film industry, unfortunately many historically significant early event photography was once made with celluloid, due to fire or wear and tear has disappeared forever. Although celluloid has been replaced in many respects by new synthetic polymers due to its flammability, celluloid continues to be produced and widely used in Europe, the former Soviet Union, the United States, and Japan (especially in the manufacture of spectacle frames, celluloid hairpins, and table tennis balls).

Celluloid is the ancestor of plastic, celluloid is the English "celluloid", he uses a mixture of nitrocellulose, camphor and ethanol to coheat it under high pressure to make it to the model, and then harden it under atmospheric pressure.

Celluloid is manufactured from nitrocellulose and raw materials such as alcohol and camphor, and it is able to be molded at the boiling point temperature of water; It can be cut, drilled, or sawn at lower temperatures; It can be a hard clump or made into a soft flake. For example, table tennis, the previous camera negatives were made of celluloid, which is very flammable, and it should be said that celluloid is the ancestor of plastic.

A large scorpion in the game card with an attack power of 2500 is called the Holy Beast Celluloid.

The celluloid in "Animation" is a style of painting.

Celluloid and celluloid are both transliterations, referring to celluloid nitrate, a synthetic resin made by Americans, as early as in the production of animation, the United States began to use celluloid transparencies made of celluloid, drawing characters on the film, and the background on the paper, you can achieve many different effects. For example, dragging film layers gives the effect of the character moving across the background.

After celluloid was used in animation, this method of drawing was widely used in hand-drawn and drawing software, and evolved into the more familiar "celluloid style", because of the heavy use of this term and the fact that celluloid is no longer used as a negative in animation, celluloid is usually referred to by default as an abbreviation for "celluloid style", and in animation, it refers to "celluloid style".

Celluloid in animation:

Celluloid and celluloid are both transliterations, referring to celluloid nitrate, a synthetic resin invented by the Americans, and later registered the trademark celluloid. It can be simply understood as a kind of plastic.

In the early days of animation in the United States, transparencies made of celluloid were already used to achieve animation effects. In the initial stage, Japanese animation continued the American practice, using celluloid to draw the "moving" parts. So the part that moves on top of the background is also called "" and this term is still used today.

Animation made with celluloid is also called "celluloid animation", and for a long time it was almost synonymous with "hand-drawn animation". Nowadays, the production process of Japanese animation is generally to make the original picture on paper, then scan it to the computer, import the image sequence into the software, color, compositit, add special effects in the post-production software, and then edit.

This process is semi-paperless, and it's not that the entire production can't be done entirely on a computer, but the traditional Japanese animation process has trained too many people to draw on paper, and it takes a lot of time to completely change the process, and it is troublesome during the period.

The introduction of celluloid coloring is as follows:

Generally, the coloring techniques of comics are mainly flat and impasto, and even if you haven't seen these two words, it feels like it's within the scope of cognition, but the "celluloid" coloring method, I think many people basically can't imagine it.

Celluloid, or celluloid, is a transliteration of celluloid nitrate, a synthetic resin, invented by the Americans, and later registered the trademark celluloid, which you can simply understand as a plastic.

In the earliest days of animation, it was Americans who began to use this plastic material for ** coloring, and it was later popularized in Japan. However, it is now definitely replaced by drawing software, but this coloring style formed after drawing on plastic film is defined by everyone as celluloid coloring.

Generally speaking, it is the animation coloring method, most of which have a large number of layers, and the things that are basically done with one layer may require several or even dozens of layers to complete celluloid.

Give you a celluloid coloring process and you might be able to understand it.

The coloring of the animation belongs to celluloid, which is flat painting.
