Original Camera Negative

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:

    But I owe something to Vincent, and that is, in the consciousness of having been useful to him, the confirmation of my own original ideas about painting. And also, at difficult moments, the remembrance that one finds others unhappier than oneself.
    Paul Gauguin (1848–1903)

    The camera has an interest in turning history into spectacle, but none in reversing the process. At best, the picture leaves a vague blur in the observer’s mind; strong enough to send him into battle perhaps, but not to have him understand why he is going.
    Denis Donoghue (b. 1928)

    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)
