A miraculous film dev.--prints made from film processed in it didn't look like prints--it was like looking thru an open window! (But I got streaks in broad expanses of gray and had to quit using it). It came in a neat little kit.
It looks like they were trying different lenses, and different film/developer combinations, to get maximum photographic resolution for use in the study. It looks like Kodak Recording Film 2475 and DK-50 beat out Tri-X and Optimate-2.
On the subject of orphan technologies, does anyone remember Polaroid Movie film? It was a fantastically pointless medium that sank without trace. I seem to remember Dixons (UK high street photo chain) shifting the camera, projector, processor kit for £60 before the system succumbed to the inevitable. Apologies for the thread segway.
