The History of Photography
A camera we think of a pinhole camera here is literally a room, say a box, with a tiny hole in it. If one puts a lens by the hole, you can bring the image to a focus and with an arrangement of mirrors, the image can be turned right-side up. That's an ancient technology. It had been known for centuries. I mentioned Leonardo da Vinci. I touched on medieval China. David Hoten has written about kind of letter and so forth, but it didn't seem to gather any force in those early days.
