Over time storage conditions such as unfavorable humidity and temperature cause film to deteriorate with variation. Exposure to air, which at first thought, might seem risky is actually necessary. Film tightly sealed in a metal or plastic can with no possibility of any air exchange creates a negative loop of auto decomposition. Film slowly out gasses and those subtle gases must be allowed to dissipate. If those gasses do not dissipate film can develop vinegar syndrome which shrinks, removes plasticity, hardens, and encourages embrittlement of the film. Your memories and work can be lost to the past.
The initial quality of film and its development after exposure also plays a significant role in its long term stability. Some film stocks are based on chemistry that was much less stable than others. For example Ansco, inexpensive store brands and even Kodak Super 8 films produced in the 1970’s usually exhibit premature dye fade and failure which damages the color balance of the images.
Debenham Media Group and MyMovieTransfer has been transferring motion picture film for well over a third of a century and are very aware of these issues and what corrective measures can be applied to produce the best results for our clients. We’ve had a front row seat observing film decay and each year have developed countermeasures to produce even better results as the film continues to age.
