It's not so much photographic as sticky :) It does take some work to get things in there, but for lines at least, once they're in there, they're in there. Don't know that I could do all of Murder, but I bet I could do My Boyfriend's Wife pretty well. And I still remember my lines from the one play in which I had a speaking role in high school -- but since the lines were "fine" and "yes, sir" that's not too impressive :)
