Snapter, Scan documents using your digital camera

It's a shareware program, when one of its kind makes it possible to use a digital camera instead of scanner to scan documents. Once photographed a document Snapter automatically takes care of it equivalent to a crawl, correcting problems in perspective, position, angle, etc..
It can also digitize a book Snapter reset itself automatically problems bending the pages.
At the moment, unfortunately, there is a free program that can do such a thing (at least AFAIK), and the price Snapter not too cheap ($ 49). So, in the absence of viable alternatives, I decided to report them.
