I had/ semi have such a memory. Evidenced by the ability to recall details about a scene, furnishings, clothing, sights, sounds and details of a place or situation that I dOn't remember noticing while I was there. Ie. I don't have to pay attention because I'll remember things I'm not even noticing. Of course my mind has dulled with age. When I was 9 I went to a place I visited only a couple times when I was 2. I told mom how the furniture used to be arranged there. I still get faded videos without sound an photos from my memories.
I read that cam Jensen too as a young kid and experimented as a teenager with the technique. I found that with practice I could sit perfectly still in a room and blinking rapidly moving only my eyes from one edge of my periphery back and forth repeatedly in a straight line I could memorize a room and prove it with trivial questions later.
Sometimes with this kind of mind you visualize when people describe things.
