I have taken PhotoReading course just a few weeks ago. The instructor emphasized that photoreading textbooks is different than photoreading other books. As there was one student in the class, the instructor dealt with her separately.

PhotoReading is natural. Anything that comes in contact with any of our 5 senses, is permanently recorded in our brain. It is about our ability to access the information already stored. For example, if I give you a keyword and send you to a city library to get the book, you'll go no where. If I give you a sentence, your chances are better but still very difficult. If I give you the name of the book and the sentence, it becomes very easy. If I give you the book, and the page, you can find within seconds. PhotoReading is about accessing information. As we grow up memorizing stuff, we forget natural way of learning. How do you think kids learn multiple languages as correctly/incorrectly as the people around them?
