All of the techniques that comprise the basic PhotoReading Whole Mind System are contained in the PhotoReading book. The basics of preparing, previewing, PhotoReading, activation (super reading, dipping, mind mapping, mind probing), and rapid reading are there and are fully explained.
The only issue that I really see for someone trying to learn from the book is a lack of self confidence in their ability to learn it from the book. There is also the lack of interaction with somebody else who could answer or rephrase the information on techniques so that if the way the book explains it doesn't make sense, you can get a different approach that does - but that is a limitation of written media, and one that is somewhat obviated by the existence of this board.
One other thing to keep in mind - PhotoReading is a personal process. I think that, once you get past the basic mechanics of it (the divergent relaxed gaze, page flipping, basic mind probing, super reading and dipping, etc.), the success of the system lies primarily in discovering how you best process information - what subtle clues your mind gives you to indicate how to further extract/recall the information that you desire. I believe that each one of us has vast, untapped potential. I also believe that the means of tapping that potential is different for each of us due to previous experience, neurophysiology, etc. There exist some general "rules of thumb" that seem to work because we all have, at root, the same brain structure, but to get maximum efficiency from our brains and minds we need to take the basic tools and adapt them to us (this is much like in the martial arts - I have never seen two black belts perform a kata the same way. Each has their own style and flair that they give it - their own personality - as well as differences in body structure that will make them move a little differently).
Finally - a step by step elaboration of the book would lead to a book-long post. Post specific questions and you will probably get specific answers. There are numerous people in this forum who have experienced consistent success with the system who are more than willing to help.
