Bromide (Japanese culture)
From Wikipedia, the free encyclopedia
In Japanese culture, bromide (ブロマイド, buromaido) is a category of commercial photographic portraits of celebrities including geisha, singers, actors and actresses of both stage and film, and sports stars. The use of the term "bromide" or "promide" occurs regardless of whether bromide paper was actually used for the photograph.
Bromide prints are made of paper infused with silver bromide, making them sensitive to light and therefore able to be used for enlargement.[1] Their use began in the 1880s, and because they had a range of finishes, they became the primary paper for black and white photography in the 1900s.

In 1921 the Marubell Company began marketing photographs of celebrities under the name promide (プロマイド, puromaido).[2] The first of these was a portrait of the film actress Sumiko Kurishima. Marubell sold the photographic paper as "bromide", and its finished photographs as "Promide". The two words eventually became synonymous and between the mid-1940s and the late-1980s sales of "bromides" were used to measure the popularity of Japanese idols.
The use of the term "bromide" to refer to a celebrity photograph remains a part of Japanese popular consciousness, and reference books such as the Kōjien Dictionary and NHK's Broadcasting Glossary recognize the term as such. "Promide" is used solely to refer to Marubell Company's bromides.
