I have been traveling around the world and parts of Asia for the last six months and this is a shot I took at Tiger Palace in Bangkok, this is one of just a few tiger sanctuaries in Thailand that do not drug the animals, and because of this they sometimes get incredibly playful, here the tigers are having a play fight in some water. What was truly amazing was the speed at which they move, one minute they are 200 yards away, the next, they are right next to you staring down like they are deciding how you taste!

This picture is not a photo of painting, landscape nor I have used any Photoshop except minor cropping, rotation and converting from raw to jpeg. It is colored threads/wool hanging from the wall in an amazing way with a nail head coming out in between. I tried to create a feeling of moon and sea.

I have seen alligators and turtles together in ponds before, but never like this! I was at Bluebill Pond in Harris Neck NWR when I saw what I thought was an alligator sunning itself on a stump. As I got closer I realized that it was actually perched on the back of a turtle! I wish I had been there to witness how this surprising esprit de corps had came to pass!

Living in Seattle I am spoiled by its beautiful skyline and the iconic Space Needle. This was not my first attempt capturing the moon with the Space Needle. After one failed attempt, I went back the next day for a second attempt and was treated with perfect conditions. As the moon rose above the horizon I was in disbelief as to how big it was, dwarfing the entire Space Needle observation deck. (© Hai Nguyen/National Geographic Traveler Photo Contest)
