We are pleased to announce the online event
Microscopy of Historical Film Colors
to launch the digital exhibition of the images resulting from a joint research project between HTW Berlin and the University of Zurich (UZH).
The event will take place online on Friday, May 28 at 6 pm CEST (9am PDT, 12pm EDT, 5pm BST) and last approx. 90 minutes.
In this project, historical film color samples stemming from the Koshofer Collection, now at UZH, have been microscopically investigated in transmission and in cross-sections at the conservation-scientific facilities of HTW Berlin. The intriguing and often stunning photomicrographs showcase the relationship between the photographic image, their material and chemical composition and the three-dimensional structure unique to the analog moving image heritage in color, while exhibiting their own peculiar beauty.
Commencing that day, the images will be accessible through a virtual exhibition gallery and via the individual color processes on the Timeline of Historical Film Colors.
