Remote
ice caves appear in a kaleidoscope of colors in these stunning shots.
Denis Budkov, 35, trekked inside the dangerous caves – which could
collapse at any moment – to capture the colorful scenes. The rainbow
caves are given their various colors by light refracting through the ice
– with the thicker the ice, the more emerald they appear. And Denis,
from Kamchatka, in the Russian Far East, also decided to add his own
take – by lighting flares to turn the normally blue hues into dark reds.
