After receiving more than 20,000 photo submissions from over 130 countries, the National Geographic Photo Contest 2011 concluded last month and the judging began. The winners were announced this week, with the grand prize awarded to Shikhei Goh for his capture of a dragonfly riding out a rainstorm in Indonesia. Goh was awarded $10,000 and a trip to the National Geographic Photography Seminar next year. National Geographic has shared the following winning photos (and honorable mentions) from this year's contest here. All captions and photos are by the individual photographers.
