History[edit | edit source]

A full explanation of the history of film can be found on Wikipedia's film[1] page.

Technical Details[edit | edit source]

The techniques used to manufacture color film changed over the years, evolving from tinting by applied colors to the subtractive color used to produce Technicolor film. The Timeline of Historical Film Colors has a chronological list of color film types.

Conservation Practices[edit | edit source]

The National Film Preservation Foundation has a list of Preservation Basics for film preservation. They recommend three key actions for preserving film:

  • printing old film onto new, more stable film stock
  • storing the original film and new master under cool-and-dry conditions
  • providing public access through surrogate video, DVD, and film copies. [2]

Film is prone to several issues of inherent vice, namely vinegar syndrome, color dye fading, and the degradation of cellulose nitrate film base.[2]

The Library of Congress has detailed the proper care, handling, and storage of motion picture film, which also includes special instructions for dealing with cellulose nitrate film.

The A/V Artifact Atlas has examples of technical issues and anomalies in audio and visual signals, particularly during preservation reformatting.
