Final answer:
Leonardo da Vinci is credited with giving the full description of the camera obscura, a device important in the development of photography.
Step-by-step explanation:
Leonardo da Vinci provided the full description of the camera obscura. The camera obscura was a device that projected an image of its surroundings on a screen and was a fundamental development leading to photography and the modern camera. While it was known to earlier scholars and used by artists since the Renaissance to aid in perspective and composition, da Vinci's detailed illustrations and descriptions from the 15th century stand out as a major contribution to our understanding of the physics and applications of the camera obscura.
