Scanners are very similar to digital cameras as both capture images using a CCD or similar chip. There are two types of scanners available - flatbed and film.
Flatbed scanners can scan photographs, text documents and 3d objects. Some of the higher end flatbed scanners can also scan 35mm or medium and large format slides (transparencies) and negatives as a scanner's optical resolution has increased over the years.
High quality flatbed scanners from Epson, Canon, HP and other manufacturers are now highly affordable and have become an essential part of both the home and work based digital photography studios.
