Do what greenlizard said.
When doing the photo reading step of the program you are not using your conscious mind. The more you concentrate and try to see or understand the words with this step the more you will "fail".
It is very very important to relax and be unstressed when using this program. Do relaxation exercises and meditation 1/2 hour or so before photoreading a book it is almost essential especially with analytical people like myself who tend to have to "know everything" and be in control all the time.
After you have allowed yourself to relax I find it for myself that using the tangerine effect and looking through the book to the floor beneath works well. Look through the book, the more the words are blured and unreadable the better with the photo reading step.
The more you concentrate your attention on the back of your head while looking through the book the better. You want your concious mind distracted from the print but not off thinking about what you need to do for tomorrow or what you are going to eat, be alert in the "NOW" but focused on the back of your head while flipping the pages.
The understanding of the material will come with the other steps of the program. If you have to use several of the activation steps multiple times don't worry about it this is normal. Remember this is a multipass program, unlike regular reading and speed reading where you read or skim a text only once.
It may seem slower to have to go back and rapid read, dip and super read several times, it is actually faster using this program versus the other ways and you get more out of the text while remembering it better and longer.
Hope this helps.
