This is an autochrome, a type of color photograph on glass, made by Stephane Passet in 1913. He captured a scene in Changping, China, where a boy stands in front of a statue of a camel at Ming Shisanling, a complex of imperial tombs. The colors are composed of tiny grains of potato starch dyed in different hues which renders an accurate depiction of what the photographer saw that day.
