Trained in computer programming, the Los Angeles-based artist John Houck examines questions of human perception and memory through the use of technologies that range from digital photography to software coding. Houck’s recent work, for example, involves still lifes composed of diverse objects from his youth that he photographs, rearranges, and reshoots. Images of these iterations are subsequently layered to create what Houck calls “aggregate photographs”—emblems of the manner in which imagination and recollection alter and distort our views of our past lives.
