City of Vancouver Archives (CVA) has recently begun a project to digitize thousands of negatives created by commercial Vancouver photographer Don Coltman who worked at Williams Brothers Photographers, and whose images were created in the years 1941-55.
Coltman’s images cover such subjects as
This is exciting news and will add much to the photo collection of Vancouver images that are available online.
Researchers will be happy to know that all Coltman’s photographs are in the public domain and will be freely available for use once the project is finished.
The negatives are made of rapidly deteriorating cellulose acetate and are stored frozen to keep them from deteriorating further.
Because cellulose acetate is toxic, the CVA had to develop a way to digitize the negatives that would still be safe for staff and figure out a way to manage preservation of the negatives while also reducing the amount of time they are out of the freezer.
