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:
“The Spacious Firmament on high,
With all the blue Ethereal Sky,
And spangled Heav’ns, a Shining Frame,
Their great Original proclaim:
Th’ unwearied Sun, from day to day,
Does his Creator’s Pow’r display,
And publishes to every Land
The Work of an Almighty Hand.”
—Joseph Addison (1672–1719)
“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)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
