More and more people are using digital cameras simply because more and more people are using Internet and computers. Digital Cameras don't replace standard 35mm film in quality (at least not yet), but they are easy to use if you want to send pictures to your friends by e-mail or you are working on multimedia projects.
In most cases the images from digital cameras should be adjusted. It is very common that images from digital cameras doesn't look too impressive in bad light conditions. Many images need to boost color saturation or make brighter midtones. Also sometimes you would like to filter noise or "too much realistic" skin on portraits.
Well the old good Brightness/Contrast sliders in image processing applications doesn't help because usually the images are ok there... You need more advanced image processing tools.
