Here's why it's unlikely he had a photographic memory:
* No mention in his writings: Dickens never mentions or alludes to having a photographic memory in his writings, letters, or journals.
* No historical records: There are no accounts from his contemporaries or biographers that suggest he possessed this ability.
* Photographic memory is rare: Photographic memory, also known as eidetic memory, is extremely rare and often limited to children. It usually fades with age.
While Dickens was undoubtedly a gifted writer with an extraordinary ability to recall and describe details, it's more likely he possessed a combination of strong visual memory, a vivid imagination, and a keen observation of the world around him.
