"On the surface at the cenote’s entrance, I had no idea what sort of space lay beneath the small pool. Only when I descended and positioned myself outside the area lit up by sun was the dark space revealed. When my eyes adjusted to the darkness, I perceived the huge dimensions of the space. My buddy, hanging above that cloud and lit by sun rays, appeared so small that I spent the whole dive shooting from distance, trying to capture the tiny diver in that huge space."
