There were past threads dicussing this issue.
Depending on how often you go to the bookstore you may wish to follow the 5 day plan ... it's short but sweet and effective.
I would modify the "Photoreading" step with a step as Pete mentioned is called "PhotoFlip". Photoflip is just that, flipping thru the book at a pace that is comfortable for you. Flip from front to back, back to front, turn book upside down, flip from front to back, back to front ... whatevev works. Do this several times, reason is to build other that conscious awareness of the material and this is achieved by several passes of the material.
