High Light

Early morning sunbeams pierce the clouds over a valley in Yangshuo County, China. Matthew Richardson captured the dramatic scene from his vantage point atop Xianggong Hill, just one of the many karst peaks that fill the region.

March of Pines

Staggered by snow, Norway spruces bend with the weather in northern Sweden’s Laponia, one of the largest wilderness areas in Europe at 3,630 square miles. “Solitude and spectacle—that’s the essence of Laponia,” says John Utsi, a writer from the town of Jokkmokk.

A Standout

A brightly hued Labord’s chameleon clings to a branch, standing in stark contrast to the surrounding dry brush. It’s a popular myth that chameleons take on the color of what they touch. Though some color changes do help them blend into their surroundings, the skin’s changing hue is in fact a physiological reaction that’s mostly for communication.

Concrete Abstract

When Larry Abraham grew bored with the photos he was capturing from a third-floor fire escape in Tacoma, Washington, he decided to change his perspective. Rather than look out, he looked down. “Color and pattern caught my eye,” he writes, “and I went to work.”

Sun Exposure

Passengers on a tour of the Northwest Passage boarded Zodiacs near Beechey Island, Canada, after hearing of a possible polar bear sighting—the first of the trip. “Our drivers maneuvered us [into] perfect positions to take pictures of the bear without stressing the animal,” writes Nina Stavlund. “You could feel the excitement, but everyone was very quiet.” With flowing adrenaline and a pounding heart—”This was, after all, my first polar bear in the wild”—Stavlund was shaking so much that she had to take a few deep breaths. “I made sure my shutter was fast and that I had a good exposure [so as] not to wash out the beautiful white coat. [When] the bear turned its head toward the sun, I saw a catch light in the eye and pressed the shutter until my buffer was full.”
