[1]Diving with sharks is like hiking in grizzly bear country or watching lions on safari. People are fascinated with sharks, and there's a visceral reaction to finding yourself in the domain of an apex predator (like the shark on the right that I photographed in Fiji). If you can get the theme song from Peter Benchley's movie [2] out of your head, it can be an amazing and thrilling experience to swim with sharks. Capturing images of these spectacular animals in their natural habitat can be even more rewarding.
Photographing Sharks
Attempting to photograph large, fast-moving predators is not like shooting reef fish, corals, and nudibranchs. Most sharks don't stay still for very long, and can move quickly and erratically.
- To freeze the action of a shark in motion, you typically need to use a fast shutter speed (1/125th of a second and faster). Using such a fast shutter speed creates the challenge of having enough light to properly expose the frame.
- I find it helpful to set my shutter speed to 1/125th of a second to start. Then I use my camera's light meter to gauge a proper exposure using ambient light, making aperture adjustments until the exposure is right.
- The strobes are used to fill in the foreground subject, which is hopefully a big ol' shark! On a sunny day in relatively shallow water, I have found that 1/125 at f11 is a good place to start when using ISO 200.
- If you are shooting directly into the sun or have exceptional light, then you want to use smaller apertures (higher f-stop values); conversely, low-light situations call for wider apertures (lower f-stop values).
- Since digital cameras have freed us from the tyranny of a 36-exposure roll of film, go ahead and experiment with adjustments to your aperture and shutter speeds.
- If the shark is moving quite quickly, try 1/160 or even faster if your shutter is able to sync with your strobes at fast speeds. A good place to start on your strobe settings is at ½ power.
- If the shark swims very close to your camera, then you will likely be able to dial that down to ¼ power or less.
Here are a few images I shot in the Bahamas earlier this year, along with some comments about how I captured the photos:
[3]Settings: ISO 200, 1/125 @ f14
This shark was shot at a depth of about 60 feet. I used a 15mm fisheye lens and waited to fire the shutter until the very last moment, when the shark in the foreground was no more than 18 inches from my camera's dome. The strobes were set near full power to illuminate the shark's profile, as well as the sponges and snappers in the background.
[4]Settings: ISO 200, 1/10 @ f22
For this image, I decided to experiment with slow shutter speeds to create a blurred effect from the movement of the shark. I was at a depth of about 50 feet and used a 17-35mm lens; again, I waited until the very last second to fire the shutter when the shark was very close to me. With the strobes on full power, I shot dozens of frames in this manner, making constant adjustments to shutter speed and aperture, until I captured one I liked.
[5]Settings: ISO 200, 1/125 @ f11
Late in the afternoon, with the sun very low in the sky, I decided to switch from a wide-angle lens to a 60mm macro lens. This was a little unconventional because you generally don't shoot large animals with a lens made for shooting small ones. But with low light levels and somewhat murky water, the conditions weren't favorable for nice, blue, wide-angle shots. I used a fast shutter speed here since macro lenses are much less forgiving than wide-angle lenses in freezing the action. I snapped this image just as the Lemon Shark was turning in front of me with a toothy "grin" on its face.

When preparing to shoot in an area known for sharks, do your homework, learn as much as possible about what you will encounter on your trip, and visualize ahead of time the shots you want to capture. Experiment with your settings! This can lead to some creative and dynamic images; don't be afraid to try something new.
As with all dives, remember to tear your eyes away from the camera now and then to simply watch the majesty of these incredible creatures. It's a thrill and a privilege to witness sharks underwater. But the speed with which they are disappearing from the ocean means we might not see sharks for much longer. Groups like CORAL are doing what they can to prevent this potential tragedy and need our support to help save these wonderful animals.
Have fun and dive safe,
