you can only 'remember' by putting it in via the photofocus/reading stage.
It activation stage is getting out of your head.
If you try it without doing the photoreading stage you'll most likely find that you've comprehended nothing.
During the photoreading stage you 'remember' nothing consciously because you deliberately bypassed the conscious mind using the photofocus state. So knowing nothing of what you saw at this stage is right. Thats why we later activate.. to fish out of our deeper mind the information that is now there.
If you skip the photoreading your comprehension of the material is almost nil. Thats what I ment when I said try it and see.
