Anotations

Scope note:

Describes 8mm film of better quality and larger frame size than the standard, which it has now largely replaced. Introduced in 1965, it has mostly been used in education, marketing, industrial training and home movies, both as an original camera film and as a reduction print from 16mm originals.
