Within the multimedia support of KGHM during 25th Economic Forum in Krynica-Zdrój we created a 360 VR video in Polkowice-Sieroszowice Mine. Because of difficult physical conditions in the mine it was not an easy task. Most of the shots we took more than 1000 m under the ground, in the high temperature and air humidity and almost complete darkness. Our job was to show different places, passing corridors and filming people and machines work. This realization allows to see the mine from the inside, feel its interior, inaccessible for most of us. Realization took place in the cooperation with Optimo Expo System.
