Leonardo da Vinci mentions a camera made by a dark cave on the edge of a valley. The hole in the cave wall serves as a camera, displaying images that rotate horizontally onto the paper. Renaissance designers used camera obscura. It actually provides a visual interpretation with the colors that dominate Western art. A box with a small hole on one side that allows a specific light source to enter and process an image that is rotated on a display screen or paper. The birth of photography is related to the invention of the method of capturing and storing images produced by camera obscura. Albertus Magnus (1193-1280) discovered silver nitrate , Georg Fabrikius (1516-1571) discovered silver chloride , and the technology described in Ibn al-Hysam’s Modern Optical Book.   Daniele Barbaro described the diaphragm in 1566.  Wilhelm Homberg explained in 1694 how light darkens certain chemicals (chemical effect).  Gifanti’s fictional novel, published by French writer Tifine de la Roche in 1760, depicts what can be interpreted as an image.
