Document Summary
Camera obscura the foundational technology of the visual image: for figuring out how light works and how people see stuff, the first technology related to the capturing of visual images is at least. The development of photography: photography writing with light . Coined by sir john herschel in 1839: silver chloride exposure light is exposed to a metal surface treated with silver chloride, which burned away to reveal the photo. Our squalid society has rushed, narcissus to a man, to gloat at its trivial image on a scrap of metal baudillaire. Louis daguerre (1839) developed technology for storing an image on a metal plate. Image could be preserved by treating with salt water. Daguerreotypes became extremely popular but the fad died out because of the consumer advantages of treated paper: talbot.

It was actually invented in europe, made commercially viable by eastman"s mass- production technology (made photography safer).
