I spent a few months early this year reading about all the memory technique books I could find and pretty much all the top specialists admit they don't have photographic memory and that they don't believe in it. The biggest problem I had was trying to get techniques designed for remembering decks of cards, or the order of royalty or names and occupations in a crowd to be relevant to my work(improving my retention of APIs/classes/etc across a variety of languages and frameworks). I didn't succeed but I honestly didn't put much work into it so that was almost certainly my own fault.
