BERLIN.- Polaroid technology revolutionized photography. Those who have used a Polaroid camera can hardly forget the unique odor of its developing emulsion and the thrill of the instant image. With the Polaroid, every image is one of a kind. This also applies to the later large-format Polacolor prints, whose developing process left behind characteristic borders. Polaroids have thus been frequently used for preliminary studies as well as a standalone medium. This was already the case early on, following the creation and presentation of the instant photograph at the Optical Society of America in 1947 by its inventor, Edwin Land and especially after he presented in 1972 the legendary SX-70 System, a collapsible, simple and affordable camera. In nearly all photographic areas from landscape and genre, portrait and self-portrait, fashion and nudes this unique imaging process has found enthusiastic devotees all over the world.
