Bob Keller is a fine art photographer with over two decades of experience in both traditional film-based and digital image making. Over the years he has been working primarily with Hasselblad 500CM and a Mamiya 645 medium format film cameras, along with a Nikon F2 35mm film camera, and with Canon D5 Mark III and Nikon z9 digital cameras, his practice is rooted in the discipline and patience of analog processes—favoring medium format film, natural light, and platinum-palladium printing techniques.

Keller's work explores themes of isolation, impermanence, and the sublime presence of nature. His photographs are often composed in rugged, remote landscapes—such as California’s Sierra Nevada, including Yosemite National Park, and the ancient rock formations of the Alabama Hills—where silence and scale shape the viewer's experience. Every image is crafted with a painter’s eye and a deep reverence for light, texture, and tonal depth.

Bob holds a Bachelor’s degree in Business from the University of Northern Iowa and an Associate of Applied Sciences from Maric College. While his education provided a structural foundation, it is his time spent in the darkroom and in the field—carrying a tripod at 10,000 feet—that defines his artistic voice.
