Photographer Ilya Naymushin spent time documenting life inside Siberian prisons, including high-security male prison camp number 17, a facility outside Russia’s Siberian city of Krasnoyarsk for male inmates who are serving a sentence for the first time and have been convicted for serious crimes. The prisoners work in wood and metal processing shops, manufacture furniture, sew clothes and do other kinds of work. Naymushin also documented the end of 32-year-old Boris Kovalyov’s time in high-security male prison camp number 5, for men who have multiple convictions for serious crimes. Kovalyov was sentenced to eight years in a high-security prison camp for drug trafficking, but was released two and a half years early for good behaviour and participation in sports and cultural activities.
