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 original of the picture you inclose, and which I return, was taken from life, and is, I think, a very true one; though my wife, and many others, do not. My impression is that their objection arises from the disordered condition of the hair.”
—Abraham Lincoln (1809–1865)
“The camera can represent flesh so superbly that, if I dared, I would never photograph a figure without asking that figure to take its clothes off.”
—George Bernard Shaw (1856–1950)
“Parents need to recognize that the negative behavior accompanying certain stages is just a small part of the total child. It should not become the main focus or be pushed into the limelight.”
—Saf Lerman (20th century)
