Selecting a Scan Size - Professional Mode
You can reduce or enlarge the size of your image as you scan. You can also select a specific scan size,
such as a common photo size like 4 × 6 inches (102 × 152 mm). This places a scan area of that size on
the preview image so you can use it to help crop the image in the correct proportions.
