A Camera That Stored Pictures as Data
In 1975, Kodak engineer Steve Sasson assembled a camera that replaced film with an electronic image sensor. The sensor converted the light entering the lens into electrical signals; circuitry turned those signals into digital information and recorded it on a cassette tape. The result was an image of about 0.01 megapixels—roughly 100 by 100 pixels, far coarser than a modern phone photo.
The cassette did not work like a roll of film. To see a picture, the recorded data had to be read back and displayed on a screen. Capturing and storing each image took 23 seconds, so this was a proof of concept, not a practical point-and-shoot camera.
The Prototype Exposed a Business Dilemma
The device’s bulk reflected how much equipment the process required: the sensor, electronics, and tape mechanism all had to fit into a portable package. Its slow recording and low resolution also made it a poor substitute for the familiar, sharp pictures people could get from film.
But the more consequential obstacle was strategic. Kodak’s established business depended on selling film and the products used to develop it. A camera that stored images electronically pointed toward a future in which customers might take pictures without buying film. Kodak shelved Sasson’s technology rather than turn that prototype into an immediate replacement for its core products.
The camera’s significance was not that it was ready to change photography in 1975. It showed that a photograph could be captured and kept without a chemical image on film. The eight-pound machine made that possibility tangible—and made the tradeoff hard to ignore: pursuing digital photography meant building a new business that could eventually compete with Kodak’s old one.
