Nicely illustrated history of photography timeline at National Geographic website. I love the first natural-color photograph ever printed in National Geographic magazine (1914).
A French cartoon about the popular rush to try photography after Louis Daguerre developed his process for the Daguerreotype in 1839. Hordes for people line up to be photographed; others sell photographic equipment. Several men hanging from gallows, potences a louer por MM les graveurs represent the death of art in the wake of photography. (from Library of Congress, via Science Faction/Getty Images)
