The rules of photography are constantly changing, if they ever really existed at all. Toying with notions of what is a “correct” or “normal” photograph, Average Subject / Medium Distance presents Andy Mattern’s complete series of playful deconstructions of mid-century photography guides. A visual treatise on colour and a wave to graphic design, the abstract compositions are accompanied by a sublime index of their component parts designed by Martin Venezky, and two essays by Matthew Kluk and Lisa Volpe.
