Cellulose Acetate Film - Rescuing Damaged Film

Rescuing Damaged Film

During early stages of decay, the film content can be rescued by transferring it to new film stock. Once the film becomes brittle it cannot be copied in its entirety. Because the gelatin emulsion usually stays intact during the degradation process, it is possible to save the image on sheet film using solvents to dissolve the base off the emulsion. Once the emulsion has been freed from the shrunken support, it can be photographed or transferred to a new support. Because of the solvents used, this is a delicate and potentially hazardous procedure and is an expensive process for a large collection. Degraded motion picture film cannot be restored in this way, but sheet films often can.

While digitization would be an ideal way to preserve the contents of cellulose acetate film, current standards do not allow for scanning at sufficient resolutions to produce a copy of the same picture and sound quality as the original. Currently, the National Film Preservation Institute advocates film-to-film transfer as the best method for film preservation, with the copies stored in proper environmental conditions.

Famous quotes containing the words rescuing, damaged and/or film:

    What stunned me was the regular assertion that feminists were “anti-family.” . . . It was motherhood that got me into the movement in the first place. I became an activist after recognizing how excruciatingly personal the political was to me and my sons. It was the women’s movement that put self-esteem back into “just a housewife,” rescuing our intelligence from the junk pile of “instinct” and making it human, deliberate, powerful.
    Mary Kay Blakely (20th century)

    It’s almost impossible to deal with a crazy man, except that he does have religious beliefs, and the world of Islam will be damaged if a fanatic like him should commit murder in the name of religion against 60 innocent people.
    Jimmy Carter (James Earl Carter, Jr.)

    The average Hollywood film star’s ambition is to be admired by an American, courted by an Italian, married to an Englishman and have a French boyfriend.
    Katharine Hepburn (b. 1909)
