Description: "VIew full lesson: http://ed.ted.com/lessons/illuminating-photography-eva-timothy The origins of the cameras we use today were invented in the 19th century. Or were they? A millenia before, Arab scientist Alhazen was using the camera obscura to duplicate images, with Leonardo da Vinci following suit 500 years later and major innovations beginning in the 19th century. Eva Timothy tracks the trajectory from the most rudimentary cameras to the ubiquity of them today. Lesson by Eva Timothy, animation by London Squared Productions."
