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:
“Original thought is like original sin: both happened before you were born to people you could not have possibly met.”
—Fran Lebowitz (b. 1951)
“The camera is a killing chamber, which speeds up the time it claims to be conserving. Like coffins exhumed and prised open, the photographs put on show what we were and what we will be again.”
—Peter Conrad (b. 1948)
“Coming out, all the way out, is offered more and more as the political solution to our oppression. The argument goes that, if people could see just how many of us there are, some in very important places, the negative stereotype would vanish overnight. ...It is far more realistic to suppose that, if the tenth of the population that is gay became visible tomorrow, the panic of the majority of people would inspire repressive legislation of a sort that would shock even the pessimists among us.”
—Jane Rule (b. 1931)
