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

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
quality. Keep in mind when you enlarge a small photo, such as 35 mm slides or
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.
