Really sorry I posted now...... Wife looks uncomfortable without mask because she had contacts in and was keeping her eyes closed, not to mention the water in the springs was pretty chilly when it hits your face....
No we did not go in a cavern, after we were out of the water the DM that was with us swam in to take the picture for us.....
I reflexively look down when I flood my mask, helps me to keep breathing, then as I exhale I tilt my head back to clear the mask......
Also this was just one of our dives, there were dives at other springs in central Florida. Our instructor was very by the book, in these pics we were practicing in shallow water per our request to get comfortable in the water....
