In the CNE’s case, it’s greater than 102,000 photograph negatives captured by the previous Alexandra Studio images firm, for the TRL.

“The majority of our negatives are cellulose acetate,” stated Shayda Spakowski, the CNE’s Event Coordinator of Arts Heritage, “which means as they start to break down in high temperature and humidity, the surface area starts to shrink and channel and off-gas very similar to vinegar.”
“When you open a drawer and get a whiff of vinegar, you know your collection has been contaminated,” Spakowski stated.
From a room within the CNE’s General Services and Archives Building, Spakowki has been meticulously cataloguing tens of 1000’s of negatives shot on the exhibition from the Fifties to the early Nineteen Eighties. Photos detailing vintage auto parades, drag boat races, and lots of different occasions she is aware of folks with a fond reminiscence of the Ex will wish to keep in mind for years to come back.
Already tons of of negatives have begun to twist and crack to the purpose of no return. Spakowski rigorously takes every detrimental in her white gloves, lays them on a scanner, and saves digital copies earlier than storing the negatives in a freezer to forestall additional degradation. She admits it might probably take quite a lot of persistence, however it’s a job she feels she has an ideal duty to hold out.

All of the acetate data have been moved right into a room on the decrease degree, the place a fragile sorting course of is underway. Thousands of newspaper data, which embrace long-defunct Toronto papers relationship again to the late 1800s, are a combination of acetate microform and polyester. Acetate lasts about 70 years, whereas polyester lasts a number of tons of of years.
