Stieglitz (1864-1946) was an American photographer and art promoter. He is best known for his NYC galleries, "Camera Work" - a photographic journal, and for promoting photography as an art form.
"Winter, Fifth Avenue" was taken in the early 1890s and over the years there have been many different versions. Stieglitz himself exhibited different versions as examples of the effect of cropping and cloning. The version shown below was published in the October 1905 issue of "Camera Work" using the photogravure (intaglio printmaking) technique.


Stieglitz did not have any issues with cropping and/or altering the original image, although I understand some of his contemporaries did...
