The rules of photography are constantly changing, if they ever really existed at all. Toying with these 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 color and a wave to graphic design, the abstract compositions in this book are accompanied by a sublime index of their component parts designed by Martin Venezky along with two informative essays by Matthew Kluk and Lisa Volpe.
