Analog photography is a commonly used term for 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).
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, which sends the picture to be processed by the camera's electronics. The signal can be transmitted or recorded on a storage device for later playback.

[edit] Popularity
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.[1] Analog photography has in fact 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 [2] Urban Outfitters, a popular clothing chain has picked up on the trend and now offers more than 60 product combinations relating to cameras most of which are film-based.
Polaroid used to be one of the most popular tools for analog instant photography, Facing the digital revolution, Polaroid stopped production of analog instant film in 2008. A company called Impossible Project acquired though Polaroid's production machines in order to produce new instant films for Vintage Polaroid cameras and to revive the analog Polaroid photography technique.
