Scanning Techniques

that scanned with 24 bit Color/8 bit Grayscale. It will not be one and a half
times.
Cropping the Image Shape
In most cases, you will want to crop the preview image before your final scan,
to eliminate white space or other unwanted images from the final product. By
combining the use of the Crop and Zoom tools, you can easily select a precise
section of the image, and then make other changes.
The Crop tool lets you select a rectangle shape of the preview image. You can
switch between the Crop tool and the Zoom tool to select exactly the part of
the image you want acquired.
If you select pixels as the unit of measure, you can see the exact size of your
selection on the rulers in the preview area.
To zoom and crop the preview image:
1. Preview the image as described in
2. With the Crop tool, select part of the image. The selection is outlined with
a broken line. Handles appear at the corners and midpoints of the
selection rectangle, and the cursor changes to a selection
crosshair.
You can move the entire selection rectangle around, or you can adjust any
edge or corner of the rectangle by moving one of its handles. When you
place the cursor over a handle, it turns to a double-headed arrow, and you
can drag that side in, out, up, or down to increase or decrease the
selection rectangle more precisely.
Use the selection handle to
move a side or corner of the
selection rectangle more
