Analog Photography
οΉ
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.
