IT'S a relatively simple idea – set up a mirror so you can capture the reflection of a dramatic landscape in a single photograph. Photographer Daniel Kukla, from New York, created a spectacular series of artworks called The Edge Effect using the technique. He clamped the mirror onto an easel and placed it in various settings in the Joshua Tree National Park, California.

Every year, in the Rostov region of Russia, a group of 40 young and not so young rural workers compete in the Bison Track Show, or more affectionately known as: Russian Flying Tractor Racing. In front of crowds numbering up to 30,000 people, a series of smoke spilling, monstrous farming machines tear round an 8km mud track, plowing through lakes and dirt mounds, their turbos screaming and tyres scrabbling to find grip.

People stop to look at the thousands of so-called “love locks”, or “love padlocks”, that hang from a fence across the Hohenzollernbruecke bridge on September 13, 2011 in Cologne, Germany. Love locks are a growing phenomenon in cities across Europe and are meant by the couples who leave them behind as a symbol of their powerful and undying love for one another.

Agueda in Portugal is the setting for this wonderful installation by Sextafeira called Floating Umbrellas. This colorful creation is a part of the Agitagueda art festival. Due to the fact that the same idea was used last year this is the second time the streets of this town have been covered with loads of vivid umbrellas, providing shade, as well as a wonderful sight. The people loved it so much that the repetitive nature of the installation does not carry the risk of becoming boring, but rather turning into a wonderful tradition.

“Lofoten Glow”. I was desperately searching a good sunrise spot this particular morning. Normally Storvatnet Lake is completely covered in snow, so you can only imagine my surprise when I saw these crazy ice formations almost being shot out of the frozen lake. I put my crampons on and took a big risk walking out. I could hear the ice cracking underneath my feet, and when you’re all alone in a fjord/canyon like this – the cracks are echoed and sound really frightening. Was it worth it? I sure think so! Photo location: Storvatnet, Lofoten Islands in Northern Norway. (Photo and caption by Stian Klo/National Geographic Photo Contest)

A Humboldt penguin stands on weighing scales whilst being photographed by members of the press during a photocall at the annual weigh-in at London Zoo in London, Britain, 24 August 2016. Every animal that is in the zoo is weighed and measured and the statistics recorded so the data can be shared with zoos across the world. (Photo by Hannah McKay/EPA)
