Processes
Exposed motion picture film will be processed according to exact chemical prescriptions at measured temperature as well as over measured time. After processing there is an original, the camera or picture original, in most cases a negative. From it a first sample is exposed on a motion-picture film printer. Again after processing there is a positive ready for inspection by the production representatives, usually by projection in the dark just like one sees a movie in a theatre.
The film lab thus needs various apparatus from developing equipment and machines, over measuring tools, cutting, editing devices, and printers to different sorts of viewing machinery including classic projectors. Besides there are sensitometers, densitometers, analysers, and array of chemical laboratory items that will help maintaining a level of repeatability of operations. Auxiliary material is also encountered within a film laboratory, for example leader film, plain plastic, to keep a developing machine threaded up.

Famous quotes containing the word processes:
“Our bodies are shaped to bear children, and our lives are a working out of the processes of creation. All our ambitions and intelligence are beside that great elemental point.”
—Phyllis McGinley (1905–1978)
“The higher processes are all processes of simplification. The novelist must learn to write, and then he must unlearn it; just as the modern painter learns to draw, and then learns when utterly to disregard his accomplishment, when to subordinate it to a higher and truer effect.”
—Willa Cather (1873–1947)
“The vast results obtained by Science are won by no mystical faculties, by no mental processes other than those which are practiced by every one of us, in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones.”
—Thomas Henry Huxley (1825–95)
