Chasing Weeds

By Jennifer Hayes

Q1 2022

How many times have you noticed the line of weeds out of the corner of your eye and driven past, around, or through it without a second glance on your way to a dive? In our case, most of the time. On a calm day off Jupiter, Florida, a wide weed line at the edge […]

Q1 2022

A STATEMENT ON FRED BUYLE’S WEBSITE briefly explains his approach to underwater photography: “To take his pictures and videos, Fred uses a simple formula: the water, available light, a camera, and one breath of air, nothing more, nothing less.” I would add to that list an extraordinary eye for composition and a passion for placing himself […]

Mexico’s Sardine Run

Q1 2022

Although striped marlins (Kajikia audax) are slower than some of their billfish cousins, their 50-mph speed is plenty fast for me. I try to swim alongside this stealth bomber of the sea as it works a baitball to separate individual sardines from the silvery mass. While getting outpaced by sailfish and black marlin might be […]

Q1 2022

Every night as the sun slips below the horizon, countless aquatic creatures begin migrating up from the deep in what is quite possibly the greatest show on Earth.

Q1 2022

The 11-liter aluminum 80, aptly named for its 11-liter internal volume and 80-cubic-foot capacity when filled to its 200 bar/3,000 PSI rated pressure, is by far the most common cylinder. Just because it is the most common, however, may not mean it is the right one for you. Cylinders come in a wide variety of […]

Underwater Smartphone Photography

Q1 2022

LIKE ANOTHER UNIVERSE, the underwater world is full of whimsical inhabitants, sinuous sharks, and huge mammals that have always fascinated people and probably always will. As a photographer, you enter completely new territory when you begin shooting underwater and learning how to adapt to the conditions of the aquatic world. Lighting subjects underwater differs significantly […]

Iceland

Q1 2022

It’s not every day you can witness the inner workings of our planet by taking a live look under the hood at the engine of creation. Some scientists claim that life on Earth began from hydrothermal vents in the ocean’s abyssal reaches. That realm is much deeper than where I float now, but otherwise it’s […]
