I still don't understand why when you put a piece of paper in a tray with solution in it, it comes up. It's still, in a sense, magic to me. It's a funny thing, you know. I've got two kids, and when they were very young, they used to come in the darkroom and I thought they'd be astounded by that. Nothing. When they got a little older, then they got astounded by it.
