A photo book as an experimental setup in which the medium informs itself and becomes a bibliophile object that explores photography as a collection and argumentation. The book is an examination of photography from the vantage point of its scientific preconditions and its apparatus-based structures on the one hand, and its uses and contexts on the other. Arrangements and comparisons of photographs explore the basic parameters of photography and photographic representation in both the analogue and the digital field; but also the conditions and impact of developments and standardisation of photographic technologies on the images of our imaginations, nourished by the images of our many different types of photographic apparatus.
