Analog photography, also known as film photography, is a catch-all term for photography that uses chemical
processes to
capture an image, typically on paper, film or a hard plate. These analog processes were the only methods
available to
photographers for more than a century prior to the invention of digital photography, which uses electronic
sensors to
record images to digital media.
In a film camera that uses photographic emulsions, light falling upon silver halides is recorded as a latent
image,
which is then subjected to photographic processing, making it visible and insensitive to light.
Contrary to the belief that digital photography gave a death blow to film, film photography not only
survived, but
actually expanded across the globe.
