Modern History. When you think of photography, you may think of it as a fairly modern invention. On the contrary, photography began with the camera obscura as early as the 10th century AD, and some evidence seems to indicate that Aristotle was familiar with this technique as early as the 4th century BC.The camera obscura was a darkened room with a tiny hole in one wall with a white screen on the opposite wall.n the early 1800s, the camera obscura had become a portable, light-tight box that contained materials and chemicals that would momentarily record the image through the lens. Cameras created in the 1800s were often crafted for looks as well as functionality.
