how is it like?
What is the phone number of the house where you grew up? Do you remember it? I remember mine, though it's been 35 years.
I don't think photographic memory is really any different than the rest of us, they just don't have any trouble recalling things.
But that's just MHO.
I don't think that people with photographic memory really exist. Rather, there are people who have more sophisticated memory techniques.
To test this, you could, for example, generate a screen of characters (80x25=2000) which are all either 1 or 0, and see if anyone can reproduce it. As the numbers become less random i.e. more compressible, you should see people able to remember better.
I remember the phone number of some of the houses that I grew up in. However, I don't remember any of my college telephone numbers.
