Wouldn't it be nice to take a picture of a position in a book and recreate it digitally?
That sounds great! but I don't know if it is doable.hope someone is working on that
It's doable. There are some chess OCR apps. If you take a picture, it will recreate the position and can even provide FEN notation for that position.
e.g.
