Camera
obscura
[Film Technology]
For hundreds of years scientists have been able to produce images of real
scenes- camera obscura- a large room that acted as a walk-in
pin-hole camera -to mid nineteenth century. Modern
cameras operate on the basic principle of the camera
obscura. Light passing through a tiny hole, or
aperture, into an otherwise light-proof box casts an image on the surface opposite the aperture.
