“Woman with Umbrella in Rain” by Raimund von Stillfried. Artist: Kusakabe Kimbei (Japanese, 1841–1934), 1870s. Commercial photography studios in Meiji-era Japan were renowned for the subtlety and refinement of their coloring techniques. This hand-tinted image of a young woman caught in a heavy rainstorm achieved its naturalistic effect by knitting together multiple strands of artifice: the greenery in the foreground was a studio prop; the flaps of the kimono were suspended by thin wires to create the impression of a strong wind; and long, diagonal marks were made on the negative to suggest streaks of rain.

Local villagers ride a local coal powered steam train on March 27, 2015 at a station in the town of Shixi , Sichuan Province, in Southern China. While China boasts the world's most extensive high-speed rail infrastructure with over 16,000 kilometers of track, the Shixi-Bagou railway is still a primary connection for local villagers between towns and is kept alive by tourist cars carrying passengers for ten times the price. The rail line came into service in the late 1950s and the train was initially used to transport coal from a now-shuttered mine before passenger carriages were added.
