Twenty years of digital photography.
Today I stumbled across this image captured with my first professional digital camera which was a 1.5 mega pixel pre year 2000 Kodak DCS 200. The camera retailed for around $20,000 stored 50 photos before it had to be attached to a computer. With no LCD screen on the back, the only way to confirm that the photo had been captured was by the sound of disc writing to the cameras hard drive.
