Great question!
When you listen to Paraliminals you are usually trying to "re-wire" beliefs that have become part of your life, that effect the things you do, the way you react to situations or don't react, etc.
When you PhotoRead, the purpose is to absorb information, and in turn develop insight and opinions, or knowledge and skills. The ideal state for learning, i.e. absorbing information, is a relaxed alert state. In this case you would not want the conscious mind to interfere the entire time you are PhotoReading.
I'll ask Paul for some further insight and explanation.
