Hi Corrina!
Welcome to the Photoreading forum.
Some background considerations. Anything you look at, hear or feel, smell etc is recorded by the mind. So here you are looking to build a pattern of emphasis that has a purpose to improve your reading skills.
Relax, you really cannot do it wrong. I have old books and am very careful with them and found it no problem how I turn the pages. Just turn the pages like your admiring the book, though you carefully turn the pages as it is good for the book.
Your mind records whatever you put in front of it. You can sit there quietly and think 'I am here recording the book as I carefully turn the pages', 'This way I will know the book entire, again at my leisure and goodly effort'.
You do not need to see the blip in the middle of the page; you do not see blips when you thoughtfully look at any picture or scene, and your mind is recording it all. Remember, the biggest factor by far is unfolding the whole skill; ie, 'using or getting it out of the memory as logic understanding what you have thoughtfully looked at with intention to know it'. Or intuition proven in/as/through experience of use.
Kind regards,
Hope some of this advice helps.
