This series was taken on the Ladoga lake shore in Leningrad region in Russia in January. The air temperature was -15 degress and there were also a stormy wind, so it was really cold. Nevertheless, I had lay down on the wet ice in order to take photos 1-4. Photos 5 and 6 was taken on the next windless but even more cold morning (about -22 degress). And I had, again, lay down on the ice. But now, I satisfied with this series.
