Drone Photo Award winners capture a dizzyingly fantastic view of the world

What does our planet look like from the sky?

The winning images of this year's Drone Photo Awards capture a dizzyingly fantastic view of the world. From high above, a field of bright green grass in Vietnam looks like faux fur – and a frozen reservoir in Kazakhstan resembles shards of broken glass.

The awards, in their fourth year, received entries from 105 countries and 2,900 professional and amateur photographers, says Luca Venturi, contest founder and art director of Siena Awards, a group based in Siena, Italy, that organizes international photo competitions.

The availability of cheaper and better drones over the past few years have helped popularize this style, especially among amateurs, says Ken Geiger, a Pulitzer Prize-winning photographer and one of this year's judges for the awards. Not only is drone photography "fabulously fun," he adds, "it's an avenue of expression helping us learn things about our planet that we never knew before."

The contest is open to all kinds of aerial photography, not just taken with drones but also blimps, kites, parachutes, helicopters and even hot air balloons.

Trees reveal their true colors

Photographer Pham Huy Trung calls his "Fishing in Mangrove Forest," taken in the Hue province of Vietnam, "a balance between humans and nature."

A former engineer, Trung says he is practical when he uses drones to take photos, always checking wind and fog levels before setting out as both can affect the quality of the photo. His ultimate goal, he says, is to find moments when a person "feels tranquility with the universe, inside and out."

Scale and color play an important role in this photograph. "The forest's white color showcases how spectacular nature is, while the red color of the fisherman's clothing represents the beauty of humans," says Trung. "Small and big, red and white — many more things should be [in harmony] together in life."

Sunbathing - on ice

In the photo "Beach Season," taken at a reservoir in Almaty, Kazakhstan, Alexandr Vlassyuk is both photographer and subject — a task he says was no small feat. He was operating the drone while posing with his friend on ice hummocks at a temperature of 14 degrees Fahrenheit. Both were nearly naked. Oh, and it was windy, he adds.

"The shooting turned out to be quite difficult," says Vlassyuk, an advertising photographer with a passion for landscapes. "I took a series of shots with two drones. Batteries were running low. In order not to freeze, we had to periodically warm ourselves up with hot tea."

Geiger says he loves the concept. "It's just so over the top that I couldn't help but vote for it. It made me smile." And the "pop of people and color" amid the broken-up ice, he says, "creates a strong entry point" for viewers.

Red-hot Havesting

MD Tanveer Hassan Rohan, a freelance photographer from New York, has always tried to get photos from the highest places possible — way before drones came into the picture. "I try to find a place where I can see the area from the top," like a rooftop, he says. "It allows me to really see that location."

When commercial drones became available, he says, he knew he had to have one. "I try to avoid gathering where many photographers fly drones. Sometimes I go to unknown places and fly my drone from a safe location to see what I can find."

One of those places is the courtyard of a chili factory in Bogura, Bangladesh, a little over 100 miles from where Rohan grew up in Dhaka. His photo "Red Chiles Harvesting" captures two lines of women sitting underneath umbrellas as they sort through a carpet of bright red chiles to be dried and preserved.
