Selecting the Right Resolution

The higher the resolution, the more detail a scanned image will have.
However, you should always keep in mind the use to which the
image will be put. An image that is scanned at maximum resolution
when there is no real need to do so simply takes up valuable disk
space. Your hard disk can quickly become filled with needlessly
large high-resolution images, which take much longer to print.
In general, photographic images, particularly landscapes, can be
scanned at lower resolution, because even the large pixels of a low-
resolution scan are not very noticeable. Such images also tend to be
very large when scanned at high resolution. On the other hand, text,
logos, diagrams and line art originals should be scanned at the
highest possible resolution. With these kinds of images, jagged
edges are much more visible.
