Quand j'étais photographe by Nadar, Félix, 1820-1910 Publisher Paris : E. Flammarion . Getty
In When I Was a Photographer (Quand j’étais photographe),
Nadar tells us about his descent into the sewers and catacombs of
Paris, where he experimented with the use of artificial lighting, and
his ascent into the skies over Paris in a hot air balloon, from which he
took the first aerial photographs. He recounts his “postal photography”
during the 1870-1871 Siege of Paris—an amazing scheme involving
micrographic images and carrier pigeons.
