Định Nghĩa và Ý Nghĩa của "film base"

What is the "film base"?

The film base is the supporting layer of a film strip that holds the light-sensitive emulsion, which is a layer containing tiny particles that record images when exposed to light. Typically made of plastic, the film base provides the structural support needed to handle and process the film. It ensures that the emulsion remains intact and correctly positioned during exposure and development.
