History of Photography

Camera Obscura • Earliest technological development in cameras • Works on the principle that light travels in a straight line • The earliest mention of this type of device was by the Chinese philosopher Mo-Ti (5 th century B. C. ) http: //brightbytes. com/cosite/what. html

The result in a completely dark room with no source of light we can puncture a small hole in the wall and observe the product of the light on the opposite wall

Camera Lucida • The original design of the camera lucida was published by William • Hyde Wollaston (1766 -1828) in 1807. Wollaston's design, used a four-sided glass prism

• The prism was cut precisely to allow the light from an object and the light from the paper to travel to the eye • Essentially a tracing tool that enables the user to trace 3 D objects
