Catching Waves

Sachi Cunningham braves the ocean to photograph big-wave surfers

Holding a heavy waterproof camera and wearing a wet suit and swim fins, Sachi Cunningham bobs in the ocean, waiting. She watches as a woman surfing nearby catches an enormous 20-foot-tall wave and rides down its crest. Cunningham snaps a close-up shot of the surfer skimming through the tunnel of water formed by the rolling wave. Then Cunningham dives before the powerful wall of water can come crashing down on top of her.

Cunningham is an ocean photographer, documentary filmmaker, and professor of multimedia journalism at San Francisco State University in California. She specializes in photographing big waves—and the women who surf them. “I’m hoping to showcase the majesty of the wave and the beauty I see in the ocean,” Cunningham says.

Sachi Cunningham bobs in the ocean. She wears a wet suit and swim fins to help her stay afloat. She points a waterproof camera at a woman surfing nearby. As the surfer catches an enormous wave, Cunningham snaps a shot. It captures the surfer gliding through the tunnel of water under the wave. Then Cunningham dives before the wave crashes and pulls her down.

Cunningham is an ocean photographer and filmmaker. She also teaches at San Francisco State University in California. Her specialty is photographing big waves, or waves at least 20 feet tall. She focuses on women surfers who ride those waves. "I'm hoping to showcase the majesty of the wave and the beauty I see in the ocean," says Cunningham.”

“Big waves only come around a few times a year,” she says. When these days arrive, Cunningham and the surfers spend the whole day on the water, from sunrise to sunset. When she arrives at the beach, Cunningham puts on her wet suit and grabs her camera equipment, swim fins, and two safety vests. Then she rides out to the waves on a Jet Ski or boat. “When a big wave is in front of you, it takes your breath away and it stops time,” she says.

One of the ways Cunningham prepares for a day at sea is by taking note of the day’s swell, or movement of the waves. “Every wave is different. They’re like snowflakes,” she says. She checks surf forecasts, which provide data about the wind and waves.

Big waves only happen a few times a year. When they do, surfers spend the whole day on the water. So does Cunningham. When she arrives at the beach, she puts on her wet suit. She grabs her camera, swim fins, and two safety vests. The big waves are often far offshore. Cunningham rides out to them on a Jet Ski or boat. "When a big wave is in front of you, it takes your breath away and it stops time.

Cunningham prepares carefully for a day at sea. She looks up the day's swell, or how the waves are moving. "Every wave is different,” she says. “They're like snowflakes." Knowing how the waves are behaving helps her stay safe.

These reports also identify how high the crests—the foamy tops of waves—are and how many seconds there are between crests. This tells Cunningham how much time she’ll have between waves to take a photo and dive under before the wave crashes. As the surfer is going down the wave, Cunningham kicks up the wave with her camera. “We try to intersect at this magic spot,” she says.

Cunningham believes that the ocean can inspire people to take care of one another and to protect the ocean itself. “There’s a saying that we’re not divided by land, we’re connected by water,” Cunningham says. “I want to share that beauty with people who aren’t able to be out there.”

Cunningham also checks surf forecasts. They tell her how high the crests, or tops, of the waves are. They also report the time between waves. This helps Cunningham figure out how long she has for each shot. As a surfer rides down a wave, Cunningham swims up it with her camera. "We try to intersect at this magic spot," she says.

Cunningham is inspired by the ocean. She hopes her photos make people want to protect it. "There's a saying that we're not divided by land, we're connected by water," she says. "I want to share that beauty with people who aren't able to be out there."
