|Skotograph by Madge Donohoe, 1920s-30s.|
I looked up what the Greek root-word for "darkness" would be. Skotos, it turns out. Then, I had to wonder if 'skotography' is a word? Yes. Yes, it is. It's two words!
Scotography (another way to spell the same word, because going from one alphabet to another is a bit flexible) is the medical practice of using non-visible wavelengths of radiation to create images. X-Ray photography is, therefor, scotography.
There's also Skotography, which was a spiritualist practice in the late 1800s and early 1900s. The idea was that, in darkness, spirits could project energy onto photographic material and produce images. Skotography was the high-tech version of a seance, or table-rapping. Treating photography as magic has a long history, about as long as the history of photography itself. Today we have 'aura photography' or Kirlian photography. And ghost-hunters that use their cameras to image the supernatural. And, there are, of course, still people who believe in skotography.
People are weird, but the few supposed skotographs I've found are actually fairly interesting in appearance. There's even a French artist who is doing a modern project inspired by the work of Madge Donohoe, a popular skotographer during the 20's and 30's.
