That's a good idea. A friend of mine created a little wooden stand and holder for his phone on his desk. Once he's done with a piece, he puts the phone in the holder, swings it around and takes a picture on a delay so he has time to hold the pages down. I believe he also has markings on the desk so he can position his papers/books correctly.

Of course, this might be way more trouble than most people are willing to go through.
