Making data digital has several advantages some of which include high compression, the ease of management, ability to organize easily, etc. On the flip side, print media is on the downhill - its very difficult to manage huge numbers of paper and they can be affected by the several problems that the agents of nature bring with them.
Digital photographs don't suffer from these vulnerabilities and their best feature is that the files can be manipulated using editing software. Printed photographs and other materials can be digitized using a flatbed scanner.
A flatbed scanner is a must have if you want quality scans. What's more is that these flatbed scanners can also serve as photo scanners. A number of companies that are into document management create scanners. A few of them are Canon, Xerox, HP, etc. Specialized scanners are available for scanning films and 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. The main components of a flatbed scanner include a light source, a photo sensitive chip fixed to a movable assembly and electronic control hardware. The scanner sends electrical signals generated by the photo sensor to the host computer, images are created by software running on the host computer.
These days most inkjet printers suitable for home and office application come with built in scanners.. They are cheap and produce acceptable scans. You can consult various technology websites to choose a suitable scanner.
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. 600, 1200 and 2400 dpi are standard resolutions. 16,32 and 48 bit sensors are common and color accuracy is determined by bit depth. Compared to a 32 bit sensor a 48 bit sensor has a higher color accuracy. Photo scanners from Canon and other brands use 2400 dpi sensors for color accuracy.
