I wonder whether photogpraphic memory really exists. There are a lot of book and softwares in internet, and the comments are so fascinating like everyone who purcased became so happy. It is really hard to trust. If you know someone who really can prove it or really good books or course please share. I do want to memorize a book and how it is possible. I am newcomer in this website so I guess you guys have a such a collosal experience and that’s why I am writing here. Thanks for everyone who will give any ideas
