A 20 minute rest after PhotoReading or postview, allowing for other than conscious processing is more than enough after you've been PhotoReading for a while. 20 minutes or sleep on it, some books you'll PhotoRead and incubate longer. You might even PhotoRead it more often before you are ready to activate..

Sleep on it means let the brain process it while you sleep. You may start activating any time. Just notice your experience. If activation is difficult, try PhotoReading it again and consider letting it incubate some more.

Try it and see. Some books you will find you can move from preview, PhotoRead, postview, straight into activation.

The advice I give is based on the revised 5 steps of the current PhotoReading course.

1 Prepare,
2 Preview,
3 PhotoRead
4 Postview,
5 Activate
