AutoSplitter will automatically recognize your photographs on the scanned image, will clip and de-rotate them. Adjust clipping, rotations and orientation manually if you desire. Scan directly with AutoSplitter or process images that are already scanned.
Some scanner manufacturers include a software like this with the scanner, some don't. This one is generally better than the vendor supplied cropping software.
The software is fairly easy to use, so be a geek or an average user, you are welcome to try it.
