You can find any number of applications that allow you to take pictures of pictures, using the iPhone’s camera. In fact, even the standard iPhone without any extra software will do that. What makes Shoebox different, however, is its ability to automatically detect the edges of a photo and then quickly crop and straighten the photo accordingly. Even if the picture was not perfectly aligned with the camera when the iPhone picture is taken, Shoebox will correct the alignment and show a picture that is perfectly aligned.
