Ei-Q (28 April, 1911–10 March, 1960) was a Japanese artist who worked in a variety of media, including photography and engraving.

He was influenced by the Surrealist aesthetic and also published essays promoting photography as an art form independent of painting. This did not imply a rejection of painting, and he worked toward what in 1935 he termed photo-dessins, a fusion of photograms and paintings.

Various artistic trends originating in Europe after World War 1, such as Russian Constructivism, the Bauhaus in Germany and Surrealism in France, left a strong impression on Japanese art and photography in the Taisho and the early Showa periods. In photography in particular, the Western influence brought a new movement called Shinko Shashin (New Photography) in the early Showa period. This exhibition was an attempt at reexamining the visual expression in the period from the perspective of the photographic work of artists from fields other than photography, focusing on the work of Koshiro Onchi, Osamu Shiihara and Ei-Q.
