1922 Kodachrome Film Test.
I’m not a photography buff, but I believe that this may be among the earliest (if not the earliest) experimentation with color motion pictures (not the ones I recall seeing in which each image on the film was hand colored).
I found this fascinating, albeit a bit eerie, seeing these beautiful young girls in living color, full of life and at the same time knowing that, since the making of the film, each of them is now very dead. I often have the same thoughts looking at old photographic images, but this was particularly spooky to me.
