haha! in case of 13 it maybe too late - on one hand... (no childish primitive drawings etc), she might have different teenage intrests now :)) but on another hand, beautiful woman (especially a young smiling and beautiful person) always give a +100 bonus to the photo. or even more
:)

so, thats a very good idea!
I must say, my girl recently becomes more and more and even MORE reluctant to cooperate with photos and shooting when I ask, hahaha!
