Earlier this month, National Geographic launched their photo-sharing platform, Your Shot (NGYourShot.com), which allows photography fans to connect with photographers and editors around virtual assignments and get direct feedback on their work.

The platform’s first assignment invites photographers to share three images that convey, ‘how photography can help us explore our changing world’. At the end of the assignment, in addition to having a photograph published in National Geographic magazine, the winning “editor’s choice” photographer will receive a personal portfolio review, a five-day National Geographic Photo Workshop in Santa Fe, N.M., and a $1,000 gift card to B&H Photo along with other prizes.

The assignment has already received 20,000 submissions and the entry period ends October 22, 2013. For more information, visit the official Explore Our Changing World assignment page.

 

 

During a visit to the Canyon lands during the monsoon season of 2013 I chased storms during the week and had this little micro thunderstorm head right at me. It was a magical moment with the sun peaking through the clouds to the west and the storm producing rain and a few lightning bolts as it passed by me.

These kids were playing the ghats of Ganges in Varanasi, India. The moment this kid saw me with my camera, she posed with the huge flag in her hand and made my day.

 

 

Nothing changes the landscape like a major volcano. I have visited Bromo Tengger National Park in Java, Indonesia many times. The usual drill is to climb to my favorite viewpoint in the early morning darkness and wait for sunrise. You never know what the new day will bring. This time it was an ash eruption of Mt Semeru highlighted by the warm colors of rising sun.

 

 

This is a self portrait of my self under a glacier in Alaska. This was by far the most amazing experience. This cave took me two + hour hike over a mountainside through swamps and about 30 minutes of walking on the glacier itself. This cave under the glacier is formed from a waterfall off the mountain that meets the glaciers edge and the cave is around 30 yards deep.When I first walked under the Glacier it was the most breathtaking and scary experience I have lived.

The Plains of Castelluccio are a karst plateau of the central-alluvial (Umbria-Marche Apennines), located in the Umbrian side of the Sibillini Mountains at the foot of Mount Carrier, within the territory of the town of Norcia, near the village of Castelluccio and the National Park of Monti Sibillini, and that is the bottom of an ancient Apennine lake, now dried up, and known for its karst features.

 

 

Oppression, interaction, collaboration. In the life cycle of nature nothing is lost, but the coexistence of different species is sometimes difficult. In Madagascar periodically recurs the archaic antagonism between man and the migratory locust, in a circle of life where the two species look for space and food for their survival. A man at the end of the day you walk towards their home with their prey on their shoulders. Inside the heavy bag in fact there are locusts that the man caught during the day.
