Film restoration

from Wikipedia, the free encyclopedia

The film restoration includes the editorial and technical restoration of a complete film or parts thereof.

Approach and technique

An indispensable preparatory work for the restoration of a film like all historical materials is the documentation of the found condition. The next step is research on the original condition as well as comparative studies with possibly preserved copies or parts thereof in order to guarantee the completeness and the most original condition of the film in image and sound. A concept for restoring the desired condition can now be drawn up and the technical restoration of the original information, the actual restoration, can be started.

As a rule, the object to be obtained, the negative , consists of cellulose nitrate or cellulose diacetate , and in the case of more recent films, cellulose triacetate or polyester . These materials differ in sensitivity and are often mechanically damaged and chemically attacked. In order not to duplicate the damage on the film layer as well as on the carrier, the raw materials are first mechanically cleaned and damage repaired and then scanned. The mechanical processing includes a repair of the perforation , here damaged areas are glued with a self-adhesive, special tape. It is important here that a tape is used that corresponds to the film shrinkage that has been determined . If possible, damaged glued areas must be restored using the wet gluing process.

Since it is a question of film rolls , film scanners (telecine or special film scanners) are used. The digitally obtained images are processed with restoration programs. The disturbances are removed and the now digitally restored images are re-recorded on film using a negative exposure device.
