Digitizing data has numerous advantages the most obvious of which are high compression, easy manageability, organization and reproducibility. Print media are difficult to manage, prone to degradation and are vulnerable to the agents of nature.
You can easily manage and manipulate digital photographs with an editing software and they don't suffer from any of these problems that the print media does. You may digitalize printed photos by using a flatbed scanner.
You should get a fladbed scanner if you're after quality scanning. These can also serve as photo scanners. Numerous document management companies like Canon, Xerox, HP make optical scanners. You need to use specialized scanners if you want to scan films and other antique documents.
Now you may be thinking: Why can't I use a camera instead of a scanner? Well, good thinking. But here's the problem: A camera takes all the picture in one shot. However, a scanner takes it line by line making it way more clear and produces high res images. If you compare the speeds, the camera wins by far. Light source, control electronics, and a photo sensor attached to a mobile assembly constitute the main components of an optical scanner. The scanner sends electrical signals generated by the photo sensor to the host computer, images are created by software running on the host computer.
Nowadays most desktop inkjet printers are available with flatbed scanners, such devices are suited for home office application. They are cheap and produce acceptable scans. If you are looking for flatbed scanners you can read up scanner reviews on various technology websites.
When choosing scanners the most important specifications to consider are the resolution and color accuracy.
Sensor resolution is measured in dots per square inch (dpi), scan quality is directly proportional to sensor resolution. Typical resolutions are 600, 1200 and 2400 dpi. Bit depth determines color accuracy. 16, 32 and 48 bit sensors are typical. Compared to a 32 bit sensor a 48 bit sensor has a higher color accuracy. The best photo scanners from Canon and other brands employ 2400dpi sensors and reproduce color accurately.
