Add info about diacetate, which was used for 35mm as early as 1909. Many prints of ambiguous base in the years preceding the switch to triacetate are diacetate. Most early 16mm is also diacetate. Note smell (mothballs/camphor) and other characteristics. --[[User:JesseCrooks|JesseCrooks]] ([[User talk:JesseCrooks|talk]]) 18:42, 26 April 2020 (PDT) | |||
