The planet we live in looks blue from the space, and what other blue elements can we find on Earth? I spent two years searching for these and made this series of blue elements above the blue planet, including the blue flames of the crater, the glowing worm in the forest, the ice floes and glaciers on the glacial lakes, and the ocean under cumulonimbus clouds, the luminescent waves formed by dinoflagellates, the most acidic lake in the world, the depths of an ice cave in the Vatna Glacier.
