Just the Prepare and PhotoRead step.
Preview is already done. Once you become a proficient PhotoReader you naturally integrate Prepare and Preview in a fluid motion like picking up a book opening it up and reading. The prepare is part of your decision to read and so is purpose. Prepare and preview you will naturally do the very first time the book comes into your hands (or on the computer) so when you decide to PhotoRead. The prepare (purpose and ideal state) is already done and you just photoread.
