National Geographic’s International Photography Contest attracts thousands of entries from photographers of all skill levels around the world every year. While this year’s entry deadline has passed, there is still time to view and vote for your favorites in the Viewer’s Choice competition. National Geographic was kind enough to let me choose a few of their entries from 2009 for display here on The Big Picture. Collected below are 25 images from the three categories of People, Places and Nature. Captions were written by the individual photographers. (25 photos total)

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.

I was in the front car of the short subway between Pudong and the Bund, and was treated to the wonderful spectacle of an oncoming train in the tunnel’s changing light show. I put my camera up to the window and shot as fast as possible to get this image. (Photo and caption by Gail von Bergen Ryan)

On my second day visiting the astounding Iguazu falls on the Brazilian side I was forced to change to my telephoto lens as my wide angle had been damaged by the water vapour. 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. (Photo and caption by Ian Kelsall) #

I took this picture on a sunny fall afternoon on a prairie near Chicago, Illinois. To improve the color saturation, I blocked the sunlight with my body. The blue background came straight from the camera. The image was not altered with any editor. (Photo and caption by Richard Susanto) #

The Darvaza natural gas crater is located in the center of the Karakum Desert in the central Asian country of Turkmenistan. 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. (Photo and caption by Natalja Silver) #

When the wave conditions are right a wave appears, infrequently, as a result of the splash back off the cliff connecting with an incoming wave. 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.

Even during the Arirang Mass Games in North Korea, the ultimate expression of the state ideology, an individual can still sometimes stand out from the crowd and break free of the collective. If only just for a moment. (Photo and caption by Brendyn Zachary) #
