Analog photography is photography that uses a progressively changing recording medium, which may be either chemical process based (e.g., photographic film or plate) or electronic (e.g., vidicon or CCD sensor). For more than a hundred years, this was the only kind. Analog photography has come to mean anything that is "not digital" despite some of controversy over the question of whether the use of film is a true analog process.
In a film camera that uses the gelatin-silver process, light falling upon photographic emulsions containing silver halides is recorded as a latent image. The latent image is subjected to photographic processing, which makes it visible and insensitive to light.
In a video camera or digital still camera, the signal is captured with a video camera tube or charge coupled device sensor, an analog device which sends the picture to be digitized and otherwise processed by the camera's electronics. The signal can be transmitted or recorded on a storage device for later playback.
Analog photography is frequently used as a title for those who are keen to work with, or do work with more traditional types of photography; dedicated online communities have been established in which like-minded individuals together share and explore historic photographic practices. Analog photography has become much more popular with younger generations who have become increasingly interested in the traditional photographic practice; sales in film-based cameras began to soar, and youth were seen to embrace some 19th-century technology Urban Outfitters, a clothing retail chain, has joined the trend and offers more than 60 product combinations relating to cameras, most of which are film-based.
