Digital Cameras: Look, No Film:
Most of us take photographs in the traditional manner with a traditional camera. We drop off our rolls of film for developing, and then enjoy the results in the form of prints and slides. Some people use image scanners to digitize photos for use in newspapers, magazines, and so on. This process may charge forever as the price of the digital cameras continues to go down. When you take a picture with a digital camera, a digitized image goes straight to 3 inch diskette or CD-ROM. Once on disk it can be loaded to a computer and manipulated as you would other graphic images.
There are many applications for digital cameras, not the least of which is expanding the family photo album.
