Flying Drone Captures Underwater Images of 300-Year-Old Coral
Coral reefs sustain about a quarter of all marine life and are shelter for more than 4,000 species. The fish that live within coral reefs are an important food staple for about 500 million people around the world.
Yet despite their crucial role in the marine ecosystem, coral reefs are mostly unmapped. Hand-mapping or photographing reefs is incredibly tedious, time-consuming and potentially inaccurate, while satellite imagery gets muddled by waves. Radar can’t penetrate the water’s surface and sonar fails in shallow areas.
To get around these limitations, Palumbi and Stanford aeronautics graduate student Ved Chirayath developed a tiny, remote-controlled drone that can film coral reefs from up to 200 feet (61 meters) above the ocean.
But ripples on the water create distortion and blur that make the drone images difficult to interpret. So after the images were gathered, Chirayath used a technique called fluid lensing to digitally remove those distortions and sharpen the images.
“The lensing takes a huge problem in looking through the surface of the water and turns it into an advantage,” Palumbi said. “It not only removes the ripples, but uses their magnification to enhance the image,” he added, referring to the fact that objects underwater tend to appear closer than they are because of how light bends when it moves from air to water.
The researchers then used a 360-degree camera to photograph the reefs from underwater.
Combining the images from both the drone and the underwater camera, the team produced gorgeous panoramic images of the reefs surrounding a marine protected area in American Samoa around Ofu Island.
The corals, some of which are 15 to 20 feet (4.5 to 6 m) wide, live in a reef called the “Village of Elders” that seems perfectly suited to these ancient corals.
As a follow-up, the team plans to combine data on water temperature and water flow with the images to see how climate change alters the reef ecosystem.

Are you just getting started out in underwater photography or are you a seasoned shooter who wants to take their images to the next level? Whatever you experience or ability, here’s an overview of underwater photography workshops.
What is an Underwater Photography Workshop?
The first thing to note is that this is not ‘school’! There are no compulsory classes and at workshops you are free to pick and choose what you take part in, or otherwise.
A huge part of learning and developing your skills is through experimentation, trial and error, responding to feedback, and honing your technique. Underwater photography workshops provide you with the perfect platform for practice and improvement.
There is no better alternative to hands on experience in an environment that is 100% dedicated to your development. Reading informative articles and watching videos on YouTube can never replace the value of one on one time with your camera rig, underwater!
Underwater photography workshops are generally structured around core components, namely: presentations, underwater practice, feedback and critique sessions, troubleshooting/one-on-one sessions, and technical support.
Other components of a workshop include dining, relaxing, and time for socializing too!
What Topics do Underwater Photography Workshops Cover?
Depending on the pro, the type of workshop and regional diving highlights, a wide range of topics may be covered from composition and lighting through to shooting techniques and editing.

- Learn from professionals

Underwater Photography Workshops in the Lembeh Strait, Indonesia
When it comes to underwater photography workshops that focus on shooting macro, muck diving, and unusual marine species, there can be no better destination on the planet than the Lembeh Strait.
The Critter Capital of the World, a Muck Diving Mecca, and the Twilight Zone are just a few of the names that have been given to this stretch of water over the years due to its high density, and diversity, of rare and unusual marine life.
Some of Lembeh’s most iconic species include the hairy frogfish, Pontohi pygmy seahorse, the Lembeh sea dragon, Mandarin fish, Bobbit worms, Rhinopias scorpionfish, flamboyant cuttlefish, tiger and harlequin shrimps, ornate ghost pipefish, harlequin crabs, and where do we start with octopus? Here’s just a few… wunderpus, mimic, blue ring, hairy, long arm, starry night, and coconut… and the list goes on!
Dive conditions in the Lembeh Strait can be extremely favourable for underwater photographers. There is little to no current making both moving around and remaining stationary a breeze. The comfortably warm water temperatures reduce the cold that can also set in when not on the move.
