125 photographs of life in Palestine before the British Mandate, ca. 1896–1919: https://publicdomainreview.org/collection/photographs-of-palestinian-life
Those aren't photographs, those are stereographs. Slightly offset images that, when viewed in a device so each image goes to just one eye, creates a full 3d image.
@kevinrns Kevin, they are both. Stereographs are composed of two photographs side by side. It's not a one or the other situation and I think one should be able to refer to stereographs (made with photographs) as photographs without being "corrected".
Yes of course.
Not merely a photograph.
That was twitter, I'm not correcting you, I'm celebrating the goofy wonderful old tech. Its a great find. It IS a photo, and two photos. And specially taken photos for a device. All is true, your post a gift.
I look forward to more finds on this account.
