PhotoReading is not a photographic memory technique. If you want to recall information you need to do something to call upon it in the first place, that may be someone asking you a question and the answer popping into your head. That is spontaneous activation. It doesn't work if you're not confident with the PhotoReading system and even then you need to recognise it's spontaneous, that means it cannot be forced and cannot be relied upon.
Play the dictionary game. You might be able to stay with it for entertainment purposes. Most find it gets boring quickly and the mind doesn't play along after a while.
