The winners of the National Geographic Photography Contest 2011 have been revealed - and the results are breathtaking.
The overall winner was named as Shikhei Goh of Indonesia for his stunning image of a dragonfly bracing for a big splash (pictured above). His photo will be published in worldwide editions of National Geographic magazine and he will receive $10,000 (approx £6,300) and a trip to National Geographic headquarters in Washington, DC, to participate in the annual National Geographic Photography Seminar in January 2012.
The competition was judged on creativity and photographic quality by a panel of experts composed of field biologist and wildlife photojournalist Tim Laman, National Geographic photographer Amy Toensing and National Geographic nature photographer Peter Essick.
More than 20,000 photographs were submitted from over 130 countries for selection in three categories: people, places and nature.
The grand-prize winner was selected from the three category winners: Nature: Shikhei Goh, Indonesia: "Splashing"; People: Izabelle Nordfjell, Sweden: "The Fjellman Family"; Places: George Tapan, Philippines: "Into the Green Zone".
