(Aside to Rob C.) : I do not recall where your affections, interest or even distaste rests in the matter of Stieglitz and O'Keefe, but after all these years I find myself pleasantly surprised by the reappearance of a third, comprising a short-lived triangle. Artist/photographer/poet/pioneer Anne Bergman, the only fellow west of the River in Stieglitz's Photo Secession photography group.
A retrospective of her work has been organized by the Nevada Museum of Art in Reno, Nevada, "Anne Brigman: A Visionary in Modern Photography" which runs through January 27.
I am temporarily locked in my immediate surrounds as I become acclimated to a bionic upgrade, but believe I would have attempted to see it in person. There is a 400 page catalogue though published by Rizzoli Electra along with a reprint of her poetry, "Songs of a Pagan" (She was manipulating her negatives and prints at the time and seemed content to fall through the cracks) What little I know to this point has me in seek mode and thought you might enjoy the distraction too.
Best to all as we move to each "yet to come~"
Lumine!
