Film Duplication

Diazo Duplicator
This piece of equipment is used to make diazo duplicates of master film. These copies are called the “working copy”, and would typically be found in libraries, research rooms, etc. They are not archival and can be replaced as necessary.
Silver Duplicator
Similar in function to the diazo duplicator it creates a silver based copy of a roll of master film, 16 or 35 mm. These are also considered “working copies”, however they have a longer use and storage life than a diazo duplicate. They can also be reversed into a positive image.
