“Steven Sasson invented the world’s first digital camera while working at Eastman Kodak in 1975. It weighed around 8 pounds (3.6kg) and shot a mere 0.01MP. It’s crazy to think how far we’ve come since those early days. We’ve gone from 30 images on a delicate cassette to thousands on something as small as a fingernail.
The Kodak digital camera prototype was made from parts of Kodak’s Super 8 movie cameras. It also included about half a dozen custom circuit boards, and used a CCD sensor which shot black & white. Images went from the sensor to the camera’s temporary memory in about 50ms. From there, it took a further 23 seconds to record one image to a digital cassette tape.
The tapes held 30 images. This number was intentionally chosen by Steven so as to be between 24 and 36 exposure films. Tapes could have stored hundreds or even thousands of images, but people simply weren’t used to that many. It seems strange, now, when a wedding photographer can easily come home with a couple of thousand shots”
