Eidetic or photographic memory is popularly defined as the ability to recall images, sounds, or objects in memory with extreme precision and in abundant volume. The word eidetic (pronounced /aɪˈdɛtɨk/) means related to extraordinarily detailed and vivid recall of visual images, and comes from the Greek word εἶδος (eidos), which is directly translatable to "seen" (as a past participle of "see").[1]
