A scanner enables you to make digital copies of existing paper photos, documents,drawings, and more. Better scanners give you the option of copying directly
from a photographic negative or slide, providing images of stunning
visual quality—assuming the original photo was halfway decent, of course.
All consumer-level scanners—called flatbed scanners—work the same way.
You place a photo or another object facedown on the glass, close the lid, and
then use software to initiate the scan. The scanner runs a bright light along the
length of the glass tray once ormore to capture the image.
