The desire for spontaneous and unpredictable distortions of developed Lomographic photos have spawned an emerging Lomographic community and the Lomographic Society International, a group of Lomographic photographers with the intention to "speak in photos and know no boundaries in our mission to snapshot every corner of the world".
Lomography emphasizes casual, snapshot photography. Characteristics such as over-saturated colors, off-kilter exposure, blurring, happy accidents, and alternative film processing are often considered part of the Lomographic Technique. From Wikipedia.
