It is much easier if you take the book out of the bag. Give a full cover scan or a pic of the front, and back covers and try not to crop them or shoot pics at too much of an angle. I softens any creases or cover damage. if you want to shoot different pics of certain areas of the book to show specific defects thats fine but always include a full front, and back pic, otherwise its like trying to piece a puzzle together. Can't grade half a book. A shot of the center fold is nice too, and mention any unseen defects. Inner cover tanning, coupons clipped, staining, torn pages etc.
