I’ve been trying to get a shot of a school of fish. In my mind’s eye it has been a favorite shot of underwater photographers to get that swirling mass of biologic frenzy under the sea. It’s not as easy as I thought. Fish don’t swirl around that much. And mostly the masses stay well away from anything as large as me trailing a large burst of bubbles and likely as not to eat them. Maybe they liked Julia better and were closer just to see what she was up to.
