Somewhere, there is a point inside these places where natural light no longer exists. We call everything beyond that point the “cave." And the part where light can still penetrate? We call that the "cavern zone." Both are beautiful, but we spend most of our time in the cave proper, since light penetrates distances ranging from nothing at all, to a few hundred feet from the entrance. So everything we see in the cave is from light we bring with us. And when we shoot photos, that is 60,000 lumens, which is equivalent to the headlights of about 30 cars. That light turns these dark places into something else, often with profoundly different effects.
