Notes from the History of Cameras

Camera Obscura uses the natural optical phenomena. The earliest cameras were room-sized with space for one or more people. There was no way of preserving other than tracing them.

Daguerreotype Camera had simple mechanisms that resembles Camera Obscura, although at a way more portable scale. A lot was developed on preservation of the image captured. There was no lens: a photographer moves the lens cap and count the minutes.
