1490
The Camera Obscura, translated as dark room, dates back to the Chinese philosopher Mo-Ti in the 5th century BC.	( Camera Obscura, Reinerus Gemma-Frisius, 1544 )
	However it is documented by Leonardo DaVinci in his 1490 writings. Camera Obscura is the physics that a very small hole in a box in a very dark room on a bright day will direct light to create an image, that is outside the hole, turned upside down.
