I am considering trying this, and I'm wondering if anyone on LW has tried this or something similar. This seems like it could work, but it also seems like it could be hokum. A simple search for "how to develop a photographic memory" returns any number of methods. If this works with the success rate that they imply, this seems like tremendously low hanging fruit.
So, this is about developing a photographic memory for text, one paragraph at a time. Is that really something you want? Why not make an Anki flashcard out of the one thing (or more, if it's a really information-dense paragraph) you most want to remember from the text?
This isn't about memorizing that one paragraph. It's about training your brain to remember things after only seeing it for a split second.
Of course, that's assuming it works.
