In 1826 or 1827, he made the View from the Window at Le Gras, the earliest surviving photograph from nature (i.e., of the picture of a real-world scene, as fashioned in a digicam obscura by a lens). Leonardo da Vinci mentions pure digital camera obscura which would possibly be shaped by darkish caves on the sting of a sunlit valley. A gap in the cave wall will act as a pinhole digital camera and project a laterally reversed, upside down image on a chunk of paper. Renaissance painters used the digicam obscura which, in reality, provides the optical rendering in shade that dominates Western Art. It is a field with a small hole in a single aspect, which permits particular gentle rays to enter, projecting an inverted picture onto a viewing display screen or paper. Isn’t it cool when a whole picture is black and white, except for a single object?
