Camera Work was the key publication of the Pictorialist movement and ran from 1903 until 1917 under the total control of Alfred Stieglitz. The quarterly publication never had a large readership swinging between about 1,000 and 400 subscribers but the influence that it had over photographers and artists of the early twentieth century was out of all proportion to this. Part of the reason was that the people who contributed photographs for Camera Work also published widely in other more popular magazines and exhibited internationally.
