A woman poses for her husband alongside a giant camera Thursday, November 7, 2013 outside the Historic Green County Courthouse in Monroe, Wis. Chicago photographer Dennis Manarchy created what's being called the world's largest camera. It's 35-feet long and 12-feet tall it's a working replica of a vintage accordion-style camera that produces 16- by 24-foot prints, the equivalent of a two-story building. The giant camera is on display in Monroe through November 17 because a Monroe company manufactured the specially-built trailer. Manarchy plans to tow the camera around the country to shoot photos of indigenous cultures. (Photo by Mark Hoffman)

“They’ve been obsessing me for years. I searched and found them in Benares, on the banks of the river Gange (India). They arrive here to get rid of everything and to wait for death. This existence can last for years, sometimes decades, almost a life. Opposite to mine, well organised and filled as a human life can be, to try in vain to push the limits of its end”. – Denis Rouvre.

“Julien Mauve is a Paris based professional web designer, front-end developer and content manager who loves innovation, experimentation and creation. Julien has taken up photography as a hobby. His collection Back to Childhood is all about bringing the long lost memories of early days into the adult life. How he came about that idea? Julien stumbled upon some of his old toys in his grandpa’s attic and felt a connection to every single one of them. Each toy brought back a fond memory”.

“Photographer Seth Casteel has definitely taken animal photography to new heights – or depths – with his hilarious photos of dogs chasing balls underwater. Casteel, who, naturally, has two dogs of his own (a mini Labradoodle and a Norwich terrier), said that he's drawn to underwater dog photography because the photos show a side of dogs that people may have never seen before”.

Shooting star by Tony Wu, US/Japan. Winner, underwater. The electrifying reproductive dance of a giant sea star. As the surrounding water filled with sperm and eggs from spawning sea stars, Wu faced several challenges. Stuck in a small, enclosed bay with only a macro lens for photographing small subjects, he backed up to squeeze the undulating sea star into his field of view. The dancing posture of spawning sea stars rising and swaying may help release eggs and sperm, or may help sweep the eggs and sperm into the currents where they fertilise together in the water.

Clash of the storms, New Mexico, US by Camelia Czuchnicki. “A clash between two storm cells in New Mexico, US, each with its own rotating updraft. The curved striations of the oldest noticeable against the new bubbling convection of the newer. It was a fantastic sight to watch and it’s the rarity of such scenes that keep drawing me back to the US Plains each year”. (Photo by Camelia Czuchnicki/Weather Photographer of the Year 2016)
