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.
Not only do digital photos have no such problems but also you can easily manipulate them using Photoshop. You may digitalize printed photos by using a flatbed scanner.
A flatbed scanner is a must have if you want quality scans. These 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. You need to use specialized scanners if you want to scan films and other antique documents.
A scanner has some of the same parts as a digital camera, whereas a camera captures the whole scene in one shot, the scanner scans the document line by line producing high resolution images. If you compare the speeds, the camera wins by far. The main components of a flatbed scanner include a light source, a photosensitivechip fixed to amovableassembly and electronic control hardware. The photo sensor scans the document by converting the light reflected from the paper to electrical signals, those signals are relayed to the host computer to which the scanner is connected. Associated software controls the scanner and creates the complete scanned image.
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 reviews.
When choosing scanners the most important specifications to consider are the resolution and color accuracy.
Resolution is measured in dpi (dots per inch), higher dpi sensors produce higher quality scans. Typical resolutions are 600, 1200 and 2400 dpi. Bit depthdeterminescolor accuracy. 16, 32 and 48 bit sensors are typical. A 48 bit sensory has a higher color accuracy compared to a 16 or 32 bit sensor. The best photo scanner from Canon and other brands employ 2400dpi sensors and reproduce color accurately.
