It was a really cold photoshoot! They made it in the Orda cave of the Perm region of Russia when it was -36 C (-32.8) outside!
According to the legend the Orda river has a spirit who helps divers in difficult situations. This became the main idea of the photoshoot. They decided to invite a two-times world champion in free diving Natalia Avseenko to play the Mistress of the Orda in the waters of the cave.
The temperature of the water was +5 C (41 F) and it was as hard as hell.
