Digital photography is displacing traditional film photography for many applications. You can buy a digital camera for anywhere from around $50 to well over $1000, depending on your needs. You can then download images from the camera to your computer, manipulate them in a graphics editor, and print the results to a high-resolution color printer. Many drug stores and malls now feature digital photography kiosks for even higher-quality prints, too. Unfortunately, most digital cameras ship only with Windows and Mac OS software, so to take advantage of these devices from Linux you need to locate an appropriate package. Fortunately, the Linux gPhoto program (http://gphoto.sourceforge.net) does an excellent job supporting a wide variety of cameras.

Although we usually tend to think of the digital camera as the best thing since sliced bread, there are both pros and cons with its use. Nothing is available on the market that does not have both a good and a bad side, but the key is to weigh the good against the bad in order to come up with the best of both worlds.
