Elena Chernyshova was in Norilsk, in Siberia (Russia) where she photographed the project ‘Days of Night, Nights of Day’ which shows the life of the inhabitants of a city with very special characteristics. Norilsk is the sixth most polluted city in the world, thanks to the huge industry of coal, cobalt and nickel mining. The medium life expectancy in the regionis ten years lower than in the rest of the Russian territory and the incidence of cancer is twice as high as the average.
