Make underwater photography a part of your world.

What is underwater photography?

Underwater photography is a world of possibility, from coral reefs off the coast of Indonesia to sharks swimming in the clear waters of the Bahamas to scuba divers encountering manta rays.

Nature photos are just the beginning, though. “Underwater photography isn’t just about taking pictures of fish and reefs and sharks and dolphins,” says photographer Joseph Esser. “There are many more different avenues.” Esser specializes in underwater wedding photography. His photos often depict couples in their wedding clothes, submerged or floating in a tropical, sun-filled sea with their clothes billowing around them.

“It’s not just taking pictures of wildlife anymore,” says Esser. “It’s people. It’s mermaid costumes. It’s bikinis. It’s models and couples.”

Staying safe with underwater photography.

Safety is the most important thing to keep in mind for an underwater photographer. “If you’re swimming in a pool, that requires a different set of skills than swimming in an ocean,” says Esser. “A lot of what we do is free swimming or free diving. You have to have a basic comfortability with your own skills.” Even swimming or snorkeling in shallow water can present certain challenges, so be sure to be comfortable with your environment before diving in.

Even on the calmest day, the chance of something going wrong in the ocean is never totally zero. Underwater photographers who take pictures of people should always get their subjects to sign liability waivers prior to a shoot.

Concern for safety also includes the safety of the animals and environment you’re photographing. Underwater photographers have to know about the animals that they’re documenting and recognize signs of fear or stress. Those signs might not always be obvious. “Pilot whales will flex their pectoral fins at you. Dolphins will blow bubbles,” says Alicia Ward, who, along with her partner, Jim, takes pictures of underwater wildlife. “People will think, ‘Oh, it’s waving at me,’ or, ‘It’s blowing bubbles,’ but these are signs of distress.”

Respect the sea life and critters around you, and make sure the fish and coral are just as beautiful when you leave as when you found them. “If you can’t walk away from an exchange feeling like you didn’t stress out an animal, you shouldn’t have taken the photo,” says Jim Ward.

A wide-angle lens or fish-eye lens is often your best bet for getting pictures of sea life. Aquatic animals won’t hold still for your shot, so take as many as possible, shoot quickly, and worry about composition in post-production. With a wide-angle lens, you’re more likely to capture that colorful fish or fleeting manta ray somewhere in the frame. Crop your images and make them adhere to the rule of thirds when you’re on dry land and editing in Adobe Photoshop Lightroom.

Try a fast shutter speed and high ISO.

Shooting quick and wide also means having a fast shutter speed and high ISO to avoid motion blur. Esser recommends an ISO of around 500.

Avoid autofocus.

Autofocus could get your camera trained on bubbles or rocks, leaving that jellyfish you wanted to photograph as just a blurred thing in the background.

Get your settings in order above the water.

Lastly, set up everything you need before going beneath the waves. “Make sure you set up everything before you get in the water,” says Esser. You don’t want to have to adjust your camera settings when you’re below the surface.

Becoming an underwater photographer.

Underwater photography can be a major opportunity for professional photographers. Being able to take your camera into the watery part of the world makes you a more flexible and adventurous photographer; it’s a great way to improve your skills in general. If you can photograph sharks and manta rays, you can definitely do weddings. If you can color-correct for briny depths, you can probably manage the white balance on a headshot. “Get creative, have fun,” says Esser. “There’s no real wrong way to do it, and the more you shoot in the water, the better you get.”
