Digital photography has proven to be one of the most world-changing
technological breakthroughs of the late 20th century. But the quest to
capture and transmit images via electrons began nearly two centuries
ago.
Piece by piece, the technologies that would make digital imaging
possible fell into place. By the 80s, 'still video' cameras captured
analog images via a semiconductor array invented at Bell Labs in 1969:
the charge-coupled device, or CCD. Which brings us to the first of
these, the most important digital cameras of all time.
