Sony World Photography Awards 2017: Winners of the Open competition are finally revealed

Ten photographs from around the world have been revealed as the winners of the Open categories of the 2017 Sony World Photography Awards, the world's largest photography competition. The winners were selected from more than 105,000 entries, with the judges looking for the best single photographs across ten categories: Architecture, Culture, Enhanced, Motion, Nature, Portraits, Still Life, Street Photography, Travel and Wildlife.

Architecture winner: Concrete Circle by Tim Cornbill, UK. "Having just arrived in Berlin on a bright summer's day, my wife and I decided to take a morning walk along the River Spree. We soon came across a large concrete building, and I was immediately struck by its geometry and scale. Across the river, I positioned myself for a single point perspective and waited for the right moment to capture it. A couple came into the viewfinder and I noticed the cyclist out of the corner of my eye. I waited for them to move into the frame and hit the shutter to try and balance the composition."

Culture winner: Tai Chi by Jianguo Gong, China. "More than 1,300 people practise tai chi along the Yangtze River in Wuhan, Hubei Province."

Enhanced winner: #3 Hearth by Lise Johansson. "The series Hearth explores what it means to feel at home. The inspiration for the work came from the personal experience of returning to Denmark after many years of living abroad, realising that I lost the warm sense of belonging I once used to have. For this project I've photographed architecture models of classic functionalist buildings, some of the earliest representations of what would later become archetypes of the Danish homes. Placing doll-like people in the models, distant, without any connection to their surroundings, Hearth seeks to apprehend the concept of home in its absence."

Motion winner: Submerged field by Camilo Diaz, Colombia. "The Colombian national team is immersed in white, grey, and black, fighting together for the ultimate position. Ana Maria and her team are constantly fighting, pushing their lungs to the limit and transforming their everyday lack of resources to an idea of opportunity. The volume of water suggests a calm while the surface gives constant chaos. An invitation was sent to participate in the European Junior Championship, as a guest team, and the South American team was named youth world champion winners in Norway."

Nature winner: Borderline by Hiroshi Tanita, Japan. "The boundary line between blue and white, ice and snow in a pond to which thin ice came during winter."

Portraits winner: Mathilda by Alexander Vinogradov, Russian Federation. "Inspired by the movie Leon. Model: Anastasiya Marinina."

Still Life winner: Sunrise at Sea by Sergey Dibtsev, Russian Federation. "It is not necessary to have money to travel by sea. Just use your imagination: fabric and paper is all you need."

Street Photography winner: Halloween Protagonists by Constantinos Sofikitis, Greece. "Halloween in NYC, one of the world's most unique parades and the spookiest autumn holiday."

Travel winner: Gassing Up At Roy's by Ralph Gräf, Germany. "Roy's Cafe, gas station and motel in Amboy, California. Part of my series 'Roadside America'. This photo was taken on the historic Route 66."

Wildlife winner: Flamingo Soul by Alessandra Meniconzi, Switzerland. "I am not a wildlife photographer but when I saw the flamingos on the shallow waters of Walvis Bay for the first time I really went crazy. I watched them from early morning till the end of the day. "

Each winning photographer receives a Sony α7 II camera with lens kit and will now compete to win the prestigious Sony World Photography Awards' Open Photographer of the Year title, a trip to the winners' awards ceremony in London in April and $5,000 (£4,000) in cash prizes. The overall winner will be announced on 20 April alongside the winners of the Professional competition (judged on a body of work).

The winners of the Open categories and the National Awards will all be shown at the Sony World Photography Awards & Martin Parr exhibition at Somerset House, London, which opens on 21 April and runs until 7 May.
