Although color photography has existed since at least 1879, it didn't become popular until many decades later. The overwhelming majority of photos taken during World War I were black and white, lending the conflict a stark aesthetic which dominates our visual memory of the war.
Hans Hildenbrand, one of nineteen photographers employed by the Kaiser to document the war, was the only German to take photos of the war in color.
