Spot Light

If you study the history of cinematography, you will uncover references to Da Vinci. In his quest to stage plays with extraordinary special effects, he experimented with lighting and the projection of images onto the stage. He would observe that this instrument was able to throw ‘a beautiful and large light’. The spotlight is a simple box with a large glass lens on one side. By changing the size of the projected object, he could create shadows that had either sharp or blurred edges. It‘s only in recent times, with the advent of motion pictures, rock concerts and spectacular light shows, that the true significance of this design could be appreciated.
