Why does film deteriorate?

Over time the chemicals on the film lose their potency and start to deteriorate. The silver halides in the films' emulsion degrade and lose their sensitivity. As a result, colors will lose their vibrancy, and contrasts will fade and grain increases. Eventually, expired film becomes foggy and unusable.

What is a degradation process?

Degradation is the process by which a chemical substance is broken down to smaller molecules by biotic means (biodegradability) or abiotic means (hydrolysis, photolysis or oxidisation).

Does film deteriorate over time?

Most negative and movie films have an expiration date. This is typically about two years after the month of manufacture, which is actually a “best if used by” date. The older the film, the more unpredictable it will be in terms of quality. Another crucial factor that determines the outcome is how film is stored.

It can be thought of as a unique flavour or style that, much like aged red wine, becomes more complex and interesting over time. The unpredictable nature of expired film makes it an exciting medium to explore, as it can produce a wide range of effects – from colour casts and graininess to a certain “misty” quality.

How does film change over time?

Movies today are often shot with much less light than their predecessors, allowing for more naturalistic effects. Take “Collateral,” for example, which was shot in the nighttime streets of LA with mostly natural light. Additionally, modern films are often much darker than films made in the gold age of Hollywood.

How long can old film be developed?

Our general rule of thumb is that anything under 10 years is pretty good. You will see some minor color shifts, your blacks will start to turn blue, maybe some indoor shots taken without a flash will be too dark, and so on. 10-20 years will see some noticeable deterioration.

The reaction of the film in the developer is not very exothermic, so there is no appreciable heating as a result of the reaction. The three primary factors that effect the amount of the developing reaction is the temperature, the time, and the concentration.

What is a film negative called?

Negative film is the name for a photographic film that will give images which have their colors inverted, after development. This inversion means that the complementary color is used. A second process (usually called making a print) is used to obtain any number of photos, which can also be in different sizes.
