For my other UMD research, high-speed imaging is necessary, so I set out to find an inexpensive and robust high speed imaging method. Current state of the art systems are many hundreds of thousands of dollars and were simply out of reach. However, after several years, a few eBay finds and some repair, I was able to get an old Cordin Model 350 Rotating Drum Camera up and running. The folks at Cordin have been super kind and generous with what little information they have left. Prof. Andrew David-Hazy of RIT has also been super supportive and helpful as he has an similar but older Dynafax camera.
It was explained to me that the last person in the world that knew how to load one of the film cassettes had died a few years back. So, my bold assertion is that I am the only human left that knows how to load one of these up. Since this technology is all but lost I have made a recording of loading and unloading film into the Model 350.
