National Geographic is once again holding their annual Photo Contest, with the deadline for submissions coming up on November 30th. For the past eight weeks, they have been gathering and presenting galleries of submissions, encouraging readers to rate them as well. National Geographic was again kind enough to let me choose some of their entries from 2010 for display here on The Big Picture. Collected below are 47 images from the three categories of People, Places and Nature. Captions were written by the individual photographers. Liquid Planet. Another picture from the Liquid Vision Series, which shows a different point of view of waves. An angle that people are not used to seeing. Praying Mantis - Pseudocreobotra wahlbergii. This beautiful whalbergii evolved through two of its nymph-stages on the Barberton Daisy at left, surviving because of its bright color which blended so well with the flower. Towards the end of its growth into an adult, it became a little more adventurous (but not much more) as pictured here. Once it had shed the layer in this picture, it became a fully-fledged adult, and departed after about two weeks. Total stay in this tiny ecosystem was approximately six weeks. Unsafe Journey. A woman is riding between the railway carriages of a local train heading north from Dhaka, the capital of Bangladesh. Her luggage is tucked under the carriage in front of her. It is the month of Ramadan, a fast which culminates in Eid-ul-Fitr, a three-day celebration. Tens of thousands of people leave the city to go to their home village and celebrate with their families. Trains are packed and many who fail to get tickets before they sell out or can't afford buying them at the black market ride on the roof of the train or, like this woman, finds a quiet spot between the carriages.
