I mean that when you've built confidence with activation you no longer worry about getting photofocus right because it has always been right. And you know it because you are already activating books.
You just PhotoRead and one day realise the text has lifted off the page taking on a 3D effect. The 3D effect is more a result of "just do it."
Purpose is the key to activation. Photofocus is just a soft gaze instead of the hard focus you normally have when you are reading.
