The Bowers is on a roll just now, with a photography exhibit featuring one saint following an exhibit celebrating another. Combine a tour of the Virgin of Guadalupe show with viewing of work by legendary American photo pioneer Imogen Cunningham for a full day in Santa Ana. Encouraged early by Edward Curtis, and a member of the California group f/64, you’ll recognize her elegantly stark modernist early 20th century aesthetic. Cunningham pioneered image-making featuring plants and nudes, deceptively simple close-ups part of a movement of realist clarity composed in scientifically artful arrangement. Later, she added to a catalog of portraits and still lifes with documentary street shots, taking pictures well into her nineties. 'Seen & Unseen' features 60 framed silver gelatin prints on loan from the Cunningham Trust, all wonderful and until now, yes, rarely seen.
