The Moment Marco Grob

Deep Cover

Putting Academy Award winner James Cameron underwater on our cover this month called for a little Hollywood magic. “We have to show science is exciting,” he says.

The National Geographic explorer-in-residence really was submerged—but inside a giant water tank at a soundstage he uses in Manhattan Beach, California (two 40-foot models of the Titanic, both seaworthy and wrecked versions, sat nearby).

Sand, plants, and bubbles were added to the image to create the illusion of Cameron on the seafloor, a place well-known to the director of Titanic and The Abyss.

Photographer Marco Grob (right, with camera) had just two hours to make the portrait before his subject had to leave to catch a flight for Australia. So Cameron, whose solo dive into the Mariana Trench, the deepest part of the ocean, is featured in this issue, donned a wet suit and went to work. He was a pro at holding his breath: “I was sometimes concerned,” admits Grob. “I’d knock on the window and say, ‘Hey, come up.’” —Margaret G. Zackowitz

Lights, Camera, Illusion

Before At far left is the unretouched image of James Cameron by Marco Grob that appears on our cover.

After At left is the same image, modified to give the illusion of Cameron undersea.
