Episodic memory is one of two types of declarative memory. Declarative memory is a type of long-term memory that refers to facts, data or events that can be recalled at will. Episodic memory allows you to consciously recall personal experiences and specific events that happened in the past.
Photographic memory is a term often used to describe a person who seems able to recall visual information in great detail. Just as a photograph freezes a moment in time, the implication for people thought to have photographic memory is that they can take mental snapshots and then recall these snapshots without error. However, photographic memory does not exist in this sense. It is easy to demonstrate this by asking people who think they have photographic memory to read two or three lines of text and then report the text in reverse order. If memory worked like a photograph, these people would be able to rapidly reproduce the text in reverse order by reading the photo. However, people cannot do this. Memory is more like pieces of a jigsaw puzzle than a photograph.
