Boulevard du Temple, Paris, c. 1838. By Louis-Jacques-Mandé Daguerre.
“Boulevard du Temple”, taken by Daguerre in 1838 in Paris, includes the earliest known candid photograph of a person. The image shows a street, but because of the over ten-minute exposure time the moving traffic does not appear. At the lower left, however, a man apparently having his boots polished, and the bootblack polishing them, were motionless enough for their images to be captured.
