Photochromes are vibrant and nuanced prints hand-coloured from black-and-white negatives. Created using a process pioneered in the 1880s, these images offer a fascinating insight into the world when colour photography was still in its infancy. A Tour of the World in Photochromes is at the Swiss Camera Museum, Vevey, until 21 August. Here: Street food in the Strada del Porto in Naples, Italy, 1899.

“«The Red Detachment of Women» (simplified Chinese: 红色娘子军) is a Chinese ballet which premiered in 1964. It is perhaps best known in the West as the ballet performed for U.S. President Richard Nixon on his visit to China in February 1972. Adapted from the earlier film of the same title under the personal direction of Zhou Enlai, which in turn adapted from the novel by Liang Xin, it depicts the liberation of a peasant girl in Hainan Island and her rise in the Chinese Communist Party”.
