Doppel-Sport Panoramic Camera : ウィキペディア英語版 | Doppel-Sport Panoramic Camera
The Doppel-Sport Panoramic Camera was created in 1912 by Julius Neubronner in Kronberg, Germany to take aerial photographs by means of pigeon photographers. Neubronner had created a pamphlet describing this process in 1909. This camera was carried by pigeons and used to spy on the French during World War I, although it was described as taking pictures that had low quality. The camera used a breast-mounted pneumatically delayed timer camera with a swing lens. The Doppel-Sport had an exposure of 3 cm x 8 cm. == Sources ==
