What is the basic principle of digital photography?

Analog-to-digital conversion

Digital photography is based on the conversion of light into digital data using sensors. This significant evolution began in the 1970s, but it was in the 1990s that the technology became widely accessible to the general public. The shift from analog to digital not only simplified the process of shooting and developing but also opened up infinite possibilities in terms of image editing and instant sharing. This transformation has turned photography into a more flexible and innovative form of art and communication, deeply impacting contemporary visual culture.
