Degas and the Ballet: Picturing Movement, Royal Academy of Arts, London

"This landmark exhibition focuses on Edgar Degas’s preoccupation with movement as an artist of the dance. Degas and the Ballet: Picturing Movement traces the development of the artist's ballet imagery throughout his career, from the documentary mode of the early 1870s to the sensuous expressiveness of his final years. 

The exhibition is the first to present Degas’s progressive engagement with the figure in movement in the context of parallel advances in photography and early film; indeed, the artist was keenly aware of these technological developments and often directly involved with them."
