Karl Struss's reputation was solidified by his inclusion in the exhibition "What the Camera Does in the Hand of the Artist" at the Newark Art Museum, held in April 1911, and an invitation by the Teacher's College for Karl Struss to organize a one-person exhibition of his views of New York City as well as to teach White's course in the summer of 1912 while White was away.
Karl Struss was invited by Stieglitz to join the Photo-Secession in 1912, which led to the publication of Karl Struss's photographs in the group's magazine Camera Work.
