There are no leaves in the photo referenced below. If you're referring to the smaller shot which shows the entire sculpture, that was just a Q&D snap to show the piece in its surroundings. I was there yesterday specifically to photograph the "face" abd to compare the 77mm and K85/1.8 lenses. But you're right, for the first shot - http://home.earthlink.net/~scbelinkoff/angel_box.jpg - a pol may have been helpful.
