Abstract: A method and apparatus for restoring to chemical stability motion picture film having an acetate base which is suffering, or which may begin to suffer, from the deterioration generally referred to as “vinegar syndrome.” The method allows films to be treated and stabilized without applying a liquid to their surfaces and without immersing them in any liquid. Instead, vapors emitted from a specially prepared, heated chemical solution permeate the film base and begin chemical reactions which ultimately restore the film. The process can be used on film that has begun to deteriorate, or it can be used, as a preventative measure, on apparently healthy film.

Abstract: A method and apparatus for restoring and enhancing both color and black and white motion picture films. In accordance with the method of the invention, vapors emitted from a heated chemical solution, but is not, at any time, immersed into the chemical solution. The identical process is used in enhancing both color and black and white films. Enhancement of black and white films in accordance with one form of the invention includes an expansion of the contract range of the film, turning murky grays into deep blacks, bringing out textures in set and costume design, and revealing artistic lighting effects that were either muted or lost. Optical soundtracks on black and white films are also improved by the method of the invention.
