anonlivros wrote a great "Photographs->Ebook" tutorial earlier this year:
Tutorial-from Paper Book to Ebook PDF - 400 pages in 4 hours
His method used a bendable "gooseneck mount" + cellphone.
On the phone, you can set it to take photos based on a noise. You can then easily:
- turn page
- make noise
- turn page
- [...]
until your photographs are complete.
From there, you can do the usual Raw-Images -> Cropping/Cleanup -> OCR.
Within that MR thread, I also described in detail how to use ScanTailor Advanced for that middle stage.
