RansenScan is a software which will speed up the scanning of your old photo or postcard collections. Its quick and easy interface means that you select, correct and save images in seconds, not minutes!
If the "sub images" are well separated RansenScan will create a list of sub images to the right of the main scanned image, as you can see above. Then you can rotate, brighten, crop etc each sub image individually.
When you are happy with your sub image you can save it, copy it to the clipboard, or print it.
