ABSTRACT
The basic structure of the camera has not changed since its development those many years ago. The name camera obscura is Latin for “darkened room.” The major improvement to the camera obscura of the 15th century was the addition of a lens to brighten and focus the image. Beyond the use of a lens to project light onto a receiving surface, the camera has changed little from the original darkened room that had one opening to allow an image to be formed. Today, a lens focuses the light from the scene being photographed and allows a larger amount of light into the darkened chamber.
