CNet Tracks the History of the Digital Camera 88
Abby Donivosif writes "CNet has up an article about the history of the digital camera. It's fascinating to note how far the technology has come in such a short amount of time. 'The camera generally recognized as the first digital still snapper was a prototype developed by Eastman Kodak engineer Steven Sasson in 1975. He cobbled together some Motorola parts with a Kodak movie-camera lens and some newly invented Fairchild CCD electronic sensors. The resulting camera, pictured above on its first trip to Europe recently, was the size of a large toaster and weighed nearly 4kg. Black-and-white images were captured on a digital cassette tape, and viewing them required Sasson and his colleagues to develop a special screen.'"

As for future cameras, I think we'll see initially, 3x sensors allowing for on the fly HDR images. After that we'll go to static video where a framed shot can be spun around to see all the out of frame info.
After that, I suppose we'll get selective depth of field, on the fly image editing, blemish correction and on the fly multi-image splicing allowing for a static family photo to be created via sliced video.
Of course we'll have meta data including temperature, GPS, wind speed, angle, height, surrounding buildings, photographer's personal ID#, satellite upload, etc.

The current and obvious trend, at least toward the low end of digital photography, is to reduce sensor size as much as possible in order to manufacture more CCDs with a single wafer. 3 times as many sensors means 3 times as much cost.

No, not really. If you could dynamically vary ISO from 100 to 1600 (which my Pentax K10D does statically) you'd get a 16-fold increase in the effective dynamic range from a single exposure that you'd need several exposures to get now. As you'd only bump up the ISO in the dark areas (and lower it in the bright areas), the noise would not be as prevalent as if you'd taken a single ISO 1600 shot today.

Foveon implements multiple sensors, period, and using them for HDR is simply a matter of how they do dynamic range.

It's also made it easier for people to exchange information. Point and shoot, and then e-mail the photos around the world in seconds. Think of all those Burmese cellphone cameras for instance. Going back 20 years, you'd mostly be reliant on photojournalists and well-to-do amateurs. Even then, those guys would have had to worry about smuggling film, or getting it secretly developed.
