Keiley became the fourth American elected to the Linked Ring, which at that time was the most prominent photographic society in the world promoting pictorialism.
Keiley joined the Camera Club in 1899 and was the fourth American to be elected to The Linked Ring. A member of the Photo-Secession, he was acknowledged to be its historian.
With Alfred Stieglitz, he developed a refinement of the glycerine process for local development of the platinum print. An art photographer as well as a historian, Keiley employed the platinotype process with a variation arrived at through his researches with Stieglitz. When Stieglitz started Camera Work in 1903 he asked Keiley to become Associate Editor, and for the next eleven years he was second only to Stieglitz in the details of publishing the journal. He contributed dozens of essays, reviews and technical articles, and he advised Stieglitz about promising new photographers from Europe.
