The Na Pali coast on the island of Kauai is full of beautiful surprises like this that you can really only appreciate from the air. Known as the “open ceiling” sea cave it’s actually a hollowed out lava tube. You can take a boat tour and enter from the ocean where there is an opening big enough for the smaller boats.
I had no idea this place existed before we took our flight, so it’s more luck than judgement that I managed to capture it here. Shooting from a helicopter is the most challenging environment I’ve encountered yet for photography.
The best tip I can think of is to sacrifice depth of field and make sure you use Shutter Priority mode. Set that shutter speed really fast. I was hovering around the 1/1000th of a second mark which left me at f4.0 most of the time. You may not get the entire frame in focus, but at least you’ll get something!
