Scanner Tips--Part 3 of 5
Believe it or not, the internal scanning element used to digitize your images can make a big difference in the quality of your scans. Currently, two distinct types of elements are used in scanners--CCD (Charge Coupled Device) and CIS (Contact Image Sensor). In general, CCD elements make for clearer and sharper scanned images, even if the material you are scanning is uneven or textured. However, CCD elements are usually larger than CIS elements and also slightly more expensive than CIS elements. If you are choosing between CCD and CIS for a pair of scanners, however, CCD is generally worth the few extra dollars.
