Selected photos from NatGeo International Photography Contest - Foto yang dipilih dari NatGeo International Photography Contest

National Geographic's International Photography Contest attracts thousands of entries from photographers of all skill levels around the world every year. Collected below are 25 images from the three categories of People, Places and Nature. Captions given by photographers themselves. Nazroo, a mahout (elephant driver), poses for a portrait while taking his elephant, Rajan, out for a swim in front of Radha Nagar Beach in Havelock, Andaman Islands. Rajan is one of the few elephants in Havelock that can swim, so when he is not dragging timber in the forest he is used as a tourist attraction. The relationship between the mahout and his elephant usually lasts for their entire lives, creating an extremely strong tie between the animal and the human being.

A sign near Groom, Texas, announcing the "largest cross in the western hemisphere" explained the large crucifix I'd been wondering about for miles on the highway; it seemed like an OK place to wait out the storm. On my way to getting stuck in the mud and a giant double rainbow, I saw this silhouetted view of the cross, splitting the sunny sky from the stormy plains.

I put my camera up to the window and shot as fast as possible to get this image.

The dried clay surface has a beautiful texture, and there is a palpable aura of mystery over the entire three-square- mile playa. The Racetrack was not entirely free of human influence though: several weeks before this taken many of the stones were stolen, leaving long trails without a traveler at the end.

In had rained solid for 10 days prior to my arrival and so the falls were at their most spectacular. Standing on the elevated viewing platform I was able to shoot this school group who stood transfixed, emphasizing the incredible size of the falls.

The blue background came straight from the camera. The image was not altered with any editor. (Photo and caption by Richard Susanto) 10 My grandfather was born and raised on our New Zealand farm. He and my grandmother were married nearly 60 years. Preparing for a photo in the barley, my grandmother lovingly reached up to adjust his hat. This was his last harvest.

The precision of the background star trails is an interesting contrast to the chaotic pattern of the firefly flashes.

The bellowing from the animals as they fought their bloody battle was incredible. They first fought in the shallows near the bank and then moved into the deeper part of the river. We don't know how it turned out but we were so glad to see the spectacle.

The two of them became "friends" after Andrew saved Scar's life.

The crater resulted after a Soviet natural gas exploration accident in the 1950s and has been burning ever since. The crater is approximately 60 meters in diameter and its depth is approximately 20 meters.

This causes the incoming wave to pop up, creating fan-like shapes. On this particular day, over the two hours I spent on the rocks, this wave only appeared once. This is that shot.

If only just for a moment. (Photo and caption by Brendyn Zachary) 21 Cary stands on a deserted road in Central Ohio, at sunset.

Two steps forward and one step back made for a challenging ascent. (Photo and caption by Andrew Cwiklewich) 25 Curious gulls on Sanibel Island, Florida. Meet my friend, "Gull-i-Bel" !!!
