When we use photofocus on the book and we see the blip page, but shouldn't the word be bury as well.
I find that people said use 'soft eyes' on the book, whats that mean??

And I do not understand about the following quote:

(I have had success just looking "through" the book, and seeing all the white space and the four corners, )

How do u do it?
Please give me some advice, I have been trying to read the dictionary in the course and no success at all.
