The ability to capture amazing photographs is something Oliver Grunewald has pretty much perfected, especially when his subjects are the rarely-seen parts of nature. One of his most interesting projects is "Serfdom of Sulphur Night" — a series of shots from the Kawah Ijen Volcano in Indonesia taken fully during the wee hours of the night. The result depicts normally infrared lava glowing with electric blue light of the sulfuric acid exhaled by the volcano. To see some extremely captivating shots, check out the gallery above and then head over to Grunwald's website to see more of this collaborative project with journalist Bernadette Gilbertas.
