Underwater world is always full of mystery to me and I am so easily amazed by those beautiful Underwater photos. However, it is so difficult to take them which requires special equipment and skill. Thanks to the “Our World Underwater international underwater photography and video competition”, hold by DivePhotoGuide.com, Wetpixel.com and Our World Underwater, we can enjoy so much talented underwater shots from all over the world. In 2010 photographers & videographers competed in seven still-image categories: Macro Traditional, Macro Unrestricted, Super Macro Traditional, Wide Angle Traditional, Wide Angle Unrestricted, Compact Cameras and Novice. I selected 20 my favorite photos in this post, and you see the full list by click here.
