The Great Pyramids. The people of Ancient Egypt believed that death on Earth was the start of a journey to the next world. The embalmed body of the King was entombed underneath or within the pyramid to protect it and allow his transformation and ascension to the afterlife. (Photo and caption by Jesus Oranday) #

The Music Of Love. This picture was taken in Tenganan Village, Bali (2010). Tenganan is the most famous Bali Aga (original Balinese) village and is located close to Candi Dasa in East Bali. A man was playing bamboo music to entertain a disabled child which is not his son, but he loves this child likes he loves his own son. (Photo and caption by Ario Wibisono) #

Brown bear, Buskin River, Kodiak Alaska. This bear had been fishing in the river on this morning. It climbed onto the bank and laid down in the grass. This photo was taken about an hour after sunrise just as the sun was starting to clear the trees. The temperature was near the dew point and steam was rising off its body. It didn’t seem at all concerned by the fishermen in the river or the photographer on the bank. (Photo and caption by James Haskins) #

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.

The child in us. Traveling from Zhangmu (Nepal-Tibet border) to the Tibetan capital - Lhasa you can see road workers all along the Friendship Highway. The Chinese industrialization has affected Tibet a great deal. But despite the Chinese government's attempts to settle Chinese population across the Tibetan Plateau, the Roof of the World still remains a place where only the Tibetans can survive its harsh climate conditions.

The baboon in front was harassing one of the babies in the troop. This male facing the camera attacked him. The whole fight was over in a few seconds but it was loud and seemingly vicious. The rest of the troop was scrambling around trying to get out of their way. There is, needless to say, always a lot of drama going on in a baboon troop. (Photo and caption by Sharon Raoli) #

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.

Lightning Strike NY Harbor. This shot was captured during a major electrical storm. There was little wind and no rain which allowed me to stay safely inside and shoot from an open window. This was the 82nd exposure out of 150 made that night. The camera was mounted on a tripod, exposures made with a cable release for 5 seconds at f10. Except for a some minor level adjustments and a square crop this was what came out of the camera. (Photo and caption by Jay Fine) #

Boise Sunrise. With the fog and morning light this looks like a place I'd love to be. If you look very closely, you can see a deer in a clearing in the center left area of the picture (small dot, head poking above bushes, see detail). (Photo and caption by Glen Hush) #

Mystery Bug. This was on my clothesline. I have no idea what it is. I have used a macro lens as the insect was only an inch or so long. We live in the Northern Rivers district of New South Wales, Australia. The rainforest around our house sometimes brings forth intriguing creatures like this. I know it looks like a studio shot but it isn't. The photograph was was taken in natural light. The background is a sheet that was serendipitously drying on the clothesline at the time. I have rotated the image to make the insect easier to examine. If anyone can tell me what it is I would be grateful. (Photo and caption by Stephen Hocking) #

Pure Elements. I drove my 4x4 over rivers to get a view of the Volcano eruption at "Fimmvorduhals" in Iceland. It was a full moon and strong winds gave me problems standing still outside the truck. I had my camera with me and zoom lens but no tripod, suddenly there was a magical moment, I was experiencing a display of nature rarely seen by man. I found my camera with the zoom lens, rushed out of the truck, trying to fight the strong wind. I pushed the camera on to the hood of the truck trying to stand still, holding my breath, I shot 30 frames, and only one shot was good. (Photo and caption by Olafur Ragnarsson) #

The Serra da Leba Road near Lubango (Huíla, Angola). This is Serra da Leba, a landmark in Angola. A road built in the 70's, it's been in the country's postcard images for decades, but all shots were taken by day. I wanted something different and tried a night shot. But it seemed impossible: pitch dark, foggy, altitude of 1,800m (5,000ft). I wanted no more than 60sec of exposure, max, to avoid digital noise. But a car takes a few minutes to climb or descend this section of the road. The fog was dense and blocking the view! Suddenly the fog cleared, a few cars went down, others went up, they met in the middle in under 60sec... Painting done! (Photo and caption by Kostadin Luchansky) #

Foot and Thistle, Mountain Gorilla of Rwanda. I was fortunate to visit the rare and endangered Mountain Gorillas in Rwanda, February of 2010. This young gorilla had fallen asleep with a thistle grasped in his foot. The thistle is one of their food sources. They learn to extract the pith from the spine-defended inedible stem. This particular gorilla demonstrates syndactyly of the third and fourth toes, a common congenital malformation also found in humans. (Photo and caption by Jim Edwards) #

Surva, the International Festival of the Masquerade Games held in the town of Pernik, Bulgaria is the biggest event of this type not only in Bulgaria but on the Balkan Peninsula as well. It promotes variations of ancient Bulgarian customs that are still alive today. These are an important part of the Bulgarian folklore tradition and are meant to be performed by single men and women. With its competitive nature, the festival is not only a venue but also a contest for the living vessels of this tradition, namely the Kukeri and Survakari. (Photo and caption by Orlin Ognyanov) #

Ki Gompa. This picture was taken when I visited the Buddhist Monastery of Ki. Ki is a tiny village in the middle of the Himalayas, and next to it is Ki Gompa (Ki Monastery). I lived with the monks for about a week, and this picture reflects the peaceful, almost heavenly atmosphere that characterizes this place. The Monastery is almost 4,000 meters high, and I had to climb almost 500 meters more to get this panorama. This place is a touch of heaven. (Photo and caption by Natalia Luzuriaga) #

Haunting Glimpse. An encounter with an elusive Canada Lynx is said to be a rare privilege. I am honored to have had the opportunity to see a Lynx up close and personal. As I photographed this beautiful cat, I felt transfixed by its wild, untamed, haunting eyes. This is a once in a lifetime chance that I will cherish forever. (Photo and caption by Janet Chester) #

Suradita Village, West Java, Indonesia. Children playing with their roosters. Actually it was not a real cockfight because the roosters didn't wear blades on their feet. Children like to play this game because they almost never have toys in their life. (Photo and caption by Ario Wibisono) #

Great Blue Heron with fish. The largest and most widespread heron in North America. When foraging, they stand silently along riverbanks, lake shores, or in wet meadows, waiting for prey to come by, which they then strike with their bills. (Photo and caption by Linh Dinh) #

A walk along the river bank. This photo was taken in Zhenyuan, Guizhou Province, China this summer. I was taking a walk along the river bank of Wuyang in the mist of a late afternoon shower. Refreshing smell after rain was mixed with the aroma from nearby food stands. In the distance, kids were playing and laughing. The tranquil and harmonious life of the local people reminds me of the joyful time I grew up in a similar small town in Southwest China. (Photo and caption by Fred Wang) #

Heavy load. One morning in August, I was on my way to pick up the newspaper. Everything was moist and wet, and I spotted this little fly on a small white flower, just outside my bedroom window. Two hours after I shot this picture I went outside again, and the fly was still sitting on the same flower - still not able to fly. (Photo and caption by Audun Wigen) #

Table Mountain. I took this picture in June 2009 while I was just outside of Cape Town, South Africa. I was working at a kids camp and took a quick shot of the sun setting over Table Mountain as we were headed in for dinner. I was in such a rush to capture the sunset while trying to keep an eye on a bunch of kids on the playground that I didn't even notice the boy in the right edge of my viewfinder. It wasn't until I was back home in Tennessee that I discovered the huge impact of this picture. The duality of the not-quite-teenage boy and the 260-million-year-old mountain in the same shot absolutely amazed me. (Photo and caption by Quinn Ballard) #

After the Crash. My dear friend, Laura, fell from the sky. The helicopter she was traveling in crashed into an open, dry field and burst info flames, killing three of the six passengers on board, including the pilot. Laura survived, but barely. She was burned, crushed, and near death. She broke 45 bones. She was pulled from the burning wreckage by her hair. To this day, she still cannot walk. While there wasn't a part of her body that was unharmed, her spirit and determination to live a full, happy life remains stronger than ever. This image taken in a lush, green field is meant to signify her rebirth. (Photo and caption by Judy Starkman) #
