Scanners

This transfers what ever you put on the scanner onto the computer as an image. There are different types of scanners including flatbed scanners, negative scanners, hand scanners and drum scanners. The flatbed scanner is generally used for home use and is usually combined with a printer and ranges from £30 to £300. The disadvantage of this scanner is that it can only scan A4 pieces of paper at most. A hand scanner is small and handheld and scans as you move it over the paper. It is generally poor quality and costs £20 plus. A negative scanner is used to scan negatives and costs around £100 and up. A drum scanner stands up tall and is high quality, it costs from £5000 to £10000. Generally the more money you spend on a scanner the better quality and the higher dpi it is.
