It is illuminating, though, to take a trip back to the phase that came one step before the camera itself.
The camera obscura was most commonly used by painters to transfer a painted scene onto their canvases. By an essentially primitive system, a scene was projected through a pin hole in a screen to the other side of a screen to form a reversed and inverted image (viz. the picture).
The next logical step was to introduce a light-sensitive material, make an exposure, and develop first a “negative”. Placing this “negative” on another sensitive paper and exposing it in a dark room to all the necessary steps of developing and stabilizing produced a picture made with a primitive machine such as, for example, a shoe box.
