Orangutan in The Rain by Andrew Suryono, Indonesia, Nature and Wildlife Category, Open Competition: "I was taking pictures of some orangutans in Bali and then it started to rain. Just before I put my camera away, I saw this orangutan took a banana leaf and put it on top on his head to protect himself from the rain.

Blaak by Cor Boers, Netherlands, Architecture Category, Open Competition: "Cube houses (Dutch: Kubuswoningen) are a set of innovative houses built in Rotterdam and Helmond in the Netherlands, designed by architect Piet Blom. High-density housing with sufficient space on the ground level. Blom tilted the cube of a conventional house 45 degrees, and rested it upon a hexagon-shaped pylon. His design represents a village within a city, where each house represents a tree, and all the houses together, a forest."Cor Boers, 2015 Sony World Photography Awards

2015 Sony World Photography Awards Arief Siswandhono cat
Timeless Affection by Arief Siswandhono, Indonesia, People Category, Open Competition: "Fina is the younger of my two daughters. She used to be scared of cats, which was the reason why we decided to adopt two kittens. We wanted Fina to learn how to live with cats, how to hold them, how to care for them and how to treat them as family members to help her overcome her fear. Now we can proudly say she did. Day by day, seven months passed by and today Fiona and the cats are best friends, and love and care for each other. In this picture I wanted to show how gracefully they're together in a frame with Leon, one of her babies."Arief Siswandhono, 2015 Sony World Photography Awards

2015 Sony World Photography Awards Miquel ngel Arts Illana
The Trace of an Ancient Glacier by Miquel Ángel Artús Illana, Spain, Travel Category, Open Competition: "Denali is six million acres of wild land, bisected by one ribbon of road. Travellers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, the 20,320ft Mount McKinley. What used to be glaciers are now white and blue rocks that contrasts with red, yellow, orange and green tundra of this vast natural paradise. The image is taken in autumn when the colours multiply and make the landscape truly remarkable."Miquel Ángel Artús Illana, 2015 Sony World Photography Awards

Covered by Courtney Colantonio-Ray, USA, Split Second Category, Open Competition: "So much of a portrait relies on the face in a photo. But when it's covered, we can see a whole different side of a person through their movement, their posture and even what we think the expression on their face will be when it's finally uncovered."Courtney Colantonio-Ray, 2015 Sony World Photography Awards
