I am building a scanner for college which involves small math symbols and other images throughout textbooks. I'm planning to put all of them onto my iPad 2 instead of carrying around those books and ruining my back. My main question is should I buy a very good $800 camera or should I split the cost and buy 2 camera's? Along with this question what brand/model camera/s should I buy? I already have all the materials for the book scanning rig except the camera/s and electronics.
Thank You!
