manageable, select the lowest possible resolution that gives acceptable quality. (If
your final output is for on-screen viewing, you can scan at 72 dpi and reduce your
file size.)
■ If you need to scan at a higher resolution, you can reduce the size of the resulting
image file by scanning only part of the image. For information about selecting
part of an image, see “Selecting the Scanning Area in the Preview Window” on

Scaling (Resizing) Images
If you plan to enlarge your image, it’s better to enlarge it by scanning at a higher
resolution. If you change the image resolution or size in an application, you lose image

wallet-size photos, you’ll need to scan at a high enough resolution to retain your
image quality, but not so high that your file size is too large to be efficient.
