The winners of the annual World Press Photo Competition have just been announced in Amsterdam and Hungarian photographer Eszter Horváth has come home with the top prize in the Nature category – but she had to go all the way to the North Pole to snap her award-winning image.

Eszter Horváth, a documentary photographer from Sopron, has been working since 2015 in the Arctic Ocean, where, amid plunging temperatures and floating ice, she captures the work of the German research ship Polarstern. The scientists have been carrying out measurements and analysis in the region, and the winning photograph shows a mother polar bear and her cub investigating equipment set up by the researchers in the ice.

Eszter’s photographs have previously been featured in National Geographic, the New York Times, the Wall Street Journal, Time and GEO Magazine.

The grand prize winner for the World Press Photo Competition is Yasuyoshi Chiba, East-African photojournalist for the French news agency AFP, with his image titled Straight Voice. The photo shows a young Sudanese man reciting a poem amid protestors. On a street in Khartoum, darkened from a power outage, his companions illuminate him with the light from their mobile phones.
