I went through a phase that lasted several months, in which I practiced daily drawing portraits and caricatures. Towards the end I debeloped a photographic memory for faces. I could go out for an evening, and later I could see all the faces I interacted with that evening crystal clear, and draw their likeness referencing only my mind's eye. When I stopped practicing portraiture the magical ability went away.
