How did digital photography replace traditional film?

Digital photography replaced chemical film processing by using electronic image sensors to capture light and store images as computer files. Early foundations in space technology and semiconductor advances like charge-coupled devices led to commercial digital cameras in the late 1990s. The integration of cameras into cell phones starting around 2000 made taking and posting photos an instantaneous part of daily life.

What we know

• Digital cameras record images using electronic photodetectors and analog-to-digital converters, eliminating the need for liquid chemical processing. [2, 5]
• Key semiconductor milestones for digital imaging include the charge-coupled device (CCD) sensor demonstrated in April 1970, with early concepts drawing from space industry remote telemetry. [2]
• Consumer digital cameras were first marketed in the late 1990s, followed by the incorporation of cameras into cell phones around 2000. [2, 4]
• Mirrorless digital cameras emerged around 2010 as competition to DSLRs and point-and-shoot cameras by offering interchangeable lenses in smaller bodies. [2]
