Camera obscura

The origin of the present day camera. In its simplest form it consisted of a darkened room or box with a small hole through one wall. Light rays could pass through the hole to transmit an inverted image of the scene outside the room onto a flat surface on its inside. It was first mentioned by Aristotle in the fourth century BCE, and employed through the centuries as an aid to drawing. These are Latin words, literally meaning "dark room." (
