The Epic Vistas of the World’s Largest Algae Farm

Steve Back’s work might look like a series of Rothko paintings, but they are, in fact, stunning pictures of algae. Hutt Lagoon is a Western Australian salt lake that contains the world’s largest system of algae farms; they get their bright hues from algae that secrete many colored substances, especially beta-carotene, which is commonly used as red food coloring.

An architectural photographer, Back was on assignment in the area when he first became interested in photographing the algae. He rented a small aircraft and headed southwest for the islands off the coast. While flying over the lagoon he was struck by the beauty and symmetry of one particular farm just south of Kalbarri.

“I had seen the lakes from ground level and they are actually quite unimpressive – you just see the muddy foreshore with lots of crystallites,” Back tells TIME, speaking from Australia.

But the view was clearly different from the air. Drawing on his architectural roots, Back was drawn to the composition and form. “As I get older I’m much more interested in the purer expression of line and form,” says Back.

The man-made pens in the middle of the lake play off each other, he adds, and the texture and lines trick the viewer into believing they are looking at a painting: “People don’t know what they are looking at,” says Back. “It invites the viewer to stop for a moment and ask what is actually going on.”

More Photography from Time


I do agree with the article author on one thing "“People don’t know what they are looking at,” says Back." and obviously he doesn't either. Actually, the red colors in the article photos are not algae at all - as the amazingly uninformed author in Time article says ("stunning pictures of algae") - it's several species of hyper-saline bacteria. Just a minimum search could have informed him. ( You see similar striking red water colors in all the salt evaporation ponds of the world - whether along Shark Bay, Australia, or San Francisco Bay, or in the Caribbean islands like Bonaire.

True the salt ponds start the evaporation process from seawater dominated by a green algae such as Dunaliella salina, but as the salinity rises with evaporation the algae are soon replaced by a succession of increasingly saline tolerant bacteria that soon give the salt evaporation ponds the water their characteristic red color. Mostly I'm amazed at the lack of technical editing from Time.
