Many historians place the beginnings of mass production around 1800, with Eli Whitney's firearms factory approximating the labor process of modern industrial production. The mass production method, generally involving the piecing together of standardized, interchangeable parts by a number of workers, reached its apex in the automobile manufacturing of the early 20th cent. Increasing automation, with attendant increases in the division of labor, allowed manufacturers to hire unskilled or semiskilled labor, which would repeatedly perform small tasks in the ultimate production of a commodity. Hence, mass production often took the form of an assembly line, in which a continuous flow of products moves steadily forward toward completion.
For most kinds of production in modern society, large amounts of capital in the form of machinery are required. Equally essential are land and its natural resources, from which the raw materials are obtained, and labor, which, with the aid of capital, extracts and transforms the raw materials. To these three primary factors of production is sometimes added a fourth: the entrepreneur who organizes the forces of production and assumes the risks. Since under capitalism production is for a market, an important function of the entrepreneur is to anticipate as accurately as possible the economic demands for goods and to produce the kind and quantity of goods that will meet that demand. In order to meet the great expenses of mass production, particularly the capital necessary in most industries, groups of speculators often take on the risks of production, and the individual entrepreneur has become less significant.
Another late 20th-century trend has been toward greater computerization of the production process; increasingly, computers are not only being integrated into the machinery of production but are replacing much of the human labor as well. Computerization has made assembly lines faster and more accurate and has given them more flexibility. Through computerized instructions, the design and manufacture of many mass-produced products can easily be modified to suit the needs of the individual customer.
Post-production occurs in the making of motion pictures, television programs, videos, audio recordings, photography and digital art. It is the general term for all stages of production occurring after the actual end of shooting and/or recording the completed work.
Post-production is in fact many different processes grouped under one name. These typically include:
Typically, the post-production phase of creating a film takes longer than the actual shooting of the film, and can take several months to complete.
Major post-production companies with articles on Wikipedia include:
