Natural World: Spirit of the Night by Will Burrard-Lucas (UK). 'To show hyenas in their element, I wanted to photograph them at night. The stars in Africa are so beautiful that I also wanted to include them in my image. I used a remote-control “BeetleCam” to position my camera on the ground so that I could photograph the hyena with the beautiful starry sky behind. This is a single exposure. I lit the hyena with two wireless off-camera flashes and used a long shutter speed to expose the stars. Since there was no moon to cause ghosting, it didn’t matter if the hyena moved after the initial flash'

Portraiture: Lost Family Portraits by Dario Mitidieri (Italy). 'March 2017 will mark the sixth anniversary of the beginning of the war in Syria. More than 470,000 people have died since. In all, 11.5% of the country’s population have either been killed or injured. 45% of the population have been displaced, 6.36 million internally and 4.8 million abroad. This is the biggest humanitarian emergency of our era. Lost Family Portraits aims to tell the story of those who have lost family members in the Syrian war, and who have made their way to the refugee camps in the Bekaa Valley, Lebanon. The empty chairs or spaces in the photographs symbolise the missing family members'

Portraiture: Hamza & Shukra/Nigeria/Jaipur/2016 by Mahesh Shantaram (India). 'Hamza came all the way from Nigeria to study human rights in India. This I found surprising. I didn't know one could study that subject here except perhaps to study its spectacular absence. Hamza is by far the most sensitive guy I've ever met on this tour of Africans in India. When I asked to photograph him in his wallpapered dwelling, he requested that he be joined by his love, Shukura, a student of nursing. He says of this relationship: "Thank you for being patient with me. Together we can prove those bitches wrong"'
