Each day, save one, for 20 years and counting, Karl Baden, an instructor in the fine arts department, has stood before the same white backdrop, stared into the same Pentax K-1000 camera, and snapped the shutter. (The date missed was of no other significance, he once told a newspaper reporter, than “I forgot.”) At top left is the first result, shot on February 23, 1987. At bottom right is the image for February 23, 2007. From left to right, the photographs are chronological, with most bearing dates of February 23. “I consciously avoid beauty [and] dynamic composition,” Baden says of the images. “Only one variable remains: whatever change may occur in my face, measured obsessively and incrementally, day after day, for the rest of my life.”
