Photographic memory exists in humans
While some children exhibit transient eidetic imagery, scientific research demonstrates that true photographic memory does not exist in humans.
The claim refers to 'photographic memory' (scientifically studied as eidetic imagery). Literature such as Haber (1979) and Chang (1971) shows that while brief visual persistence appears in a small minority of children, it fades with age, is virtually nonexistent in adults, and does not represent an ability to 'photograph' and recall complex pages of information at will. The balance of evidence clearly refutes the existence of human photographic memory.

Haber (1979) reviews decades of research on eidetic imagery (often conflated with photographic memory) and concludes that while brief persisting visual images occur in a small percentage of children, they are virtually nonexistent in adults and do not correlate with superior cognitive abilities.

Chang (1971) finds that while a small percentage of children demonstrate persistent visual images (eidetic imagery), it is rare, not widely prevalent, and does not equate to a functional 'photographic memory' that persists into adulthood.
