Again flipping through an unpleasantly moldy copy of The Best of Popular Photography… from November 1951, H.M. Kinzer writes on Nadar: “he succeeded in photographing the Arc de Triomphe for the first time as the birds saw it.” Of course, in the days of cumbersome wet collodion plates, it would have probably been unimaginable to predict that later miniaturization of photographic paraphernalia would one day allow birds to literally photograph it themselves. (Full disclosure - try as I might (a good 30 seconds of Google Images delving), I could not find an actual pigeon-facilitated photograph of the Arc de Triomphe itself.* But the point stands.)

The article rhapsodizes at length on Nadar (Gaspard Felix Tournachon until the name change; self-portrait above, and in caricature, below**) and his A-list portraiture. Much more interesting is the flying darkroom part. To his naysayers/skeptics/those worried about his survival, this pithy reply: “Nothing is so easy as what was done yesterday; nothing is so difficult as what will be done tomorrow.” And difficult it was. Some technical details: “A big orange-and-black tent, impermeable to light, was suspended from the rigging above, and a smoky safelight was mounted inside. ‘It was warm inside,’ recalled Nadar, ‘but our collodion plates didn’t mind, submerged in their cool baths.’”
Much trial and many errors later, it wasn’t until a hydrogen-less balloon ride in the nude (”The cumbersome tent was left behind: he would do his processing later on the ground. This done, the balloon struggled to rise, bounded up once or twice, and settled sadly back to earth. Only a few more pounds would do the trick. Modesty was sacrificed to science–Nadar removed all his clothes and jettisoned them. Success! The balloon rose…”) that the unflappable experimenter would realize the chemical impediment that was the hydrogen itself (”‘Silver iodide and hydrogen sulfide,’ he reminded himself, ‘make a bad marriage which can bring forth no offspring.’”). None of Nadar’s hard-won aerial photographs seem to have survived in the intervening years, sadly; image below is in fact Boston, not Paris, on October 13, 1860, photographed by James Wallace Black from a captive balloon.

*I could not even find, to my surprise, a picture of a pigeon at the Arc de Triomphe.
