Inspired by the work of the Czech philosopher Vilém Flusser, Arjan de Nooy proposes a distinctive outlook on photography in 20 propositions. These are the opening moves of 'Photology', a photobook about photography played by the author. The title refers both to the study of the medium as to the logic of photography games. Using found photographs, postcards, online images, and photo simulations, De Nooy constructs a personal overview. Typical categories such as history, chance, style, information, genres such as the portrait, and various photo theorists are treated in a playful manner.
