Scanning Tips
Scan photos instead of printed pictures
Images from magazines or books are composed of tiny dots. The typical resolution for color typesetting is 180 or 300 dpi, so scanning at higher resolutions offers no advantages. As a matter of fact, higher resolutions may even be worse because the scanner often sees white dots in between the printed color dots. To preserve accurate toning details, if possible, scan photographs instead of printed materials.
Scan good quality images and text
You always lose some information when you scan. By carefully choosing your images and settings, you can minimize this problem. For example, don't try to scan extremely light or dark images or those with very low contrast.
Limit the image size when possible
Small images require much less hard disk space and processing time than large ones. Be aware of how much disk space you have on your system when you acquire your pictures. If your available disk space is limited, you may only be able to copy a few photographs to your camera or computer.
