History and Technology of Photography

Professor Nicholas Allen proposes that the Turin Shroud is the world's first photograph, challenging the timeline of photographic invention. He suggests that medieval technology, including the camera obscura, could have enabled early photography. Historical references, such as Plato's writings, support the existence of image projection techniques. The video demonstrates a camera obscura and discusses the development of lenses in medieval Italy, indicating that the technology for creating sharp images might have been available to artists of that era.
