Object of the month

Our object of the month is a white, frozen T-shirt on our colleague's clothesline, printed with the "Op-Art-Silhouette" motif by F.C. Gundlach.  

Acetic acid syndrome is a familiar phenomenon in this category. In four sheet film negatives we recently discovered, the deterioration process manifests itself in a remarkable way.

Transparent plastic sleeves, which have been used for decades to store slides, are now proving to be a conservation problem.

We recently found a whole box full of slides in the archive, from which we extracted a 35mm color slide. We want to take this discovery as an opportunity to reflect on the question of why so few color prints have survived from the work of many photographers who worked on commission.

This month we are presenting three 35mm film canisters from the Perutz company. These historical black and white films illustrate the challenges of archiving and preserving old film materials.
