Roberts Diptychs consists of cyanotypes and digital photos taken at Roberts Bird Sanctuary in Minneapolis. It examines different ways to document space and time photographically. Each cyanotype required 10-20 minutes of exposure. Once I developed them, I re-photographed the prints digitally in the same places I captured the originals. The digital photos show the contrast between the soft, white and blue cyanotypes and the actual surroundings they document—as well as the sharpness of the digital photos themselves, which only required an exposure time of 1/125 of a second.
