The original camera negative (OCN) is the film in a motion picture camera which captures the original image. This is the film from which all other copies will be made. It is known as raw stock prior to exposure.
The size of a roll varies depending on the film gauge and whether or not a new roll, re-can, or short end was used. 100 or 400 foot rolls are common in 16mm, while 400 or 1000 foot rolls are used in 35mm work. While these are the most common sizes, other lengths such as 200, 800, or 1200 feet may be commercially available from film stock manufacturers, usually by special order. 100 and 200 foot rolls are generally wound on spools for daylight-loading, while longer lengths are only wound around a plastic core. Core-wound stock has no exposure protection outside its packaging, and therefore must be loaded into a camera magazine within a darkroom or changing bag/tent in order to prevent the film being fogged.

Famous quotes containing the words original, camera and/or negative:
“When we look back, the only things we cherish are those which in some way met our original want; the desire which formed in us in early youth, undirected, and of its own accord.”
—Willa Cather (1873–1947)
“The camera can photograph thought. It’s better than a paragraph of sweet polemic.”
—Dirk Bogarde (b. 1921)
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
