Outstanding photos in the underwater cave

These amazing pictures are not photoshop. They were made in Orda underwater cave, which is located on the outskirts of the tiny village of "Horde" Perm region.
For such a dangerous dive was invited world champion Natalia Avseenko freediving.
Yeah, probably, it was terribly cold photo shoot, because outside the cave air temperature was -32.8 degrees below zero, and the water temperature is only 5 degrees above zero.
